5. Variation of this embodiment
[0015]
1. The structure of the optical fiber system
　First, referring to FIG. 1, the configuration of an optical fiber system 1000 according to an embodiment of the present disclosure. As shown in FIG. 1, the system according to this embodiment includes an optical transceiver 100 and an optical transceiver 200. Optical transceiver 100 includes a connector portion 102, the optical transceiver 200 includes a connector portion 202. A connector portion 202 of the connector portion 102 and the light receiving device 200 of the optical transceiver 100 is connected by optical cable 300.
[0016]
Further, the optical transceiver 100, the light emitting portion 110 of the optical data, a lens 120, the light-emitting end 130, has a receiving end 140, the lens 150 and the light receiving unit 160 of the optical data. Similarly, the optical transceiver 200 includes a receiving end 210, a lens 220, the light receiving portion 230, the light-emitting end 240, lens 250 and light emitting portion 260 of the optical data.
[0017]
　In Figure 1, corresponding to the optical cable 300 having one optical transmission path, the optical transmitter-receiver 100 and optical transceiver 200 has one light emitting portion, one lens, although the configuration including one light-emitting end, the optical cable 300 due to the provision of a plurality of optical transmission line (optical fiber 400), the light emitting portion of the optical transceiver 100 and the optical transceiver 200, a lens and a light emitting end, corresponding to the number of optical transmission lines (number of channels) It is plurality. Similarly, in FIG. 1, corresponding to the optical cable 300 having one optical transmission path, the optical transmitter-receiver 100 and optical transceiver 200, one receiving end, one lens, the configuration including one light receiving portion showed, since the optical cable 300 is provided with a plurality of optical transmission lines, the light receiving end of the optical transceiver 100 and the optical transceiver 200, the lens and the light receiving portion are a plurality provided corresponding to the number of optical transmission paths.
[0018]
　Further, in FIG. 1, the lens 120 of the position of the light-emitting end 130, lens 250 may be disposed at the position of the light-emitting end 240. Emitting end 130, the light emitting end 240 indicates the interface through which light emission toward the connector 102, 202. The lens 150 is in the position of the receiving end 140, the lens 220 may be disposed at the position of the light receiving end 210. Receiving end 140, the light receiving end 210 represents an interface for receiving light incident from the connector portion 102, 202.
[0019]
2. Light loss of the transmission path
　Figure 2 shows an example of an optical loss in the transmission path in an optical fiber system 1000 (light-emitting unit 110 → the lens 120 → the light emitting end 130 → optical cable 300 → receiving end 210 → lens 220 → the light receiving portion 230) . The light energy of the light emitting section 110 of the optical data is attenuated by the lens unit 120 and the light emitting end 130 of the optical transceiver 100. Furthermore, light energy, even in the optical cable 300 is attenuated in proportion to its length. Furthermore, light energy, also attenuated by the light-receiving end 210 and the lens 220 of the optical transceiver 200, the energy which has reached attenuated the light receiving portion 230 is converted opto-electric, desired data signal is generated. Further, the optical loss in the transmission path from the optical transmitting and receiving device 200 via the optical cable 300 reaches the optical transceiver 100 is similar.
[0020]
　Light audiovisual data transmitted in the cable system and other data for bit error rate (BER) is 10 -10 to 10 -12 it is desirable to be less. In the light receiving portion 230 of the optical transceiver 200, to the light energy having a margin above the minimum value of light energy to satisfy the BER value it is necessary to increase the optical energy of the light emitting section 110 of the optical transceiver 100 shall.
[0021]
　However, if or optical cable 300 from the connector portion 202 of the connector portion 102 and the optical transceiver 200 of the optical transceiver 100 is disengaged, the optical cable 300 itself is disconnected is assumed. Increasing the optical energy of the light emitting section 110, in such a case, light energy body, especially not deny the possibility of harm to the retina of the eye.
[0022]
3. Safety standards relating to laser products
　Therefore, for the purpose of preventing failure to the user by the laser products, the laser safety standards, "JIS C6802: Laser Safety Standards Product" and "JIS C6803: Laser Product Safety - optical fiber of the communication system safety "is defined. In the JIS C6802, for the purpose of representing a risk during device operation equipped with laser light sources, it is defined by dividing the "class" determined by the laser exposure amount during device itself used to seven.
[0023]
　An optical fiber system for use in consumer, among the "class" must correspond to "Class 1" (Hazard Level 1) or "Class 1M" (hazard level 1M). The risk of "Class 1", also continues to look without blinking for 100 seconds laser light, a retina damage is not level, "Class 1M" is the same as "Class 1", the magnifying glass, etc. when using an auxiliary optical system, there is a possibility that a risk, it is necessary to display the reminder.
[0024]
　In each class, the output regulation value of light energy is subdivided by the maximum interruption time of the wavelength of the laser beam and the laser beam. Figure 3 is a schematic diagram showing the relationship between the optical energy of the maximum cut-off time and the laser beam in an automatic power attenuation function to function during loss when the cable is cut and the optical connector (Automatic Power Reduction, henceforth referred to as APR function).
[0025]
　Here, the automatic power attenuation function, if the omission of the cut cable and optical connectors has occurred, a function also attenuate the light output from the normal data transmission period within the maximum cut-off time, equipped with this feature Re if data transmission at high optical power than class 1 is permitted by the standard (JIS C6803, IEC60825).
[0026]
　In Figure 3, it shows a case of the largest cut-off time is short APR function, maximum cut-off time is a case 2 long APR function from the case 1. In Class 1, the light output at a normal data transmission period is limited to P1 below. The case 1, the case 2, the cable cut at time t0, or when the optical connector disconnection occurs, the power of light emitted to the outside is defined to be equal to or less than a predetermined value. Case 1, Case 2, both the optical output after the lapse of the maximum cut-off time is reduced to P4. Maximum breaking time T1 of the case 1 is set to be shorter than the maximum cut-off time T2 of the case 2. When the power of the light emitted after time t0 to the environment or less constant value, the light output in the normal data transmission period is greater than the long casing 2 of the maximum breaking time T1 is more of a short case 1 of up breaking time T1 can do.
[0027]
　In Case 1, since the maximum interruption time T1 is short, it is possible to increase the output P3 of the laser beam normal data transmission period and will, it is possible to increase the margin for satisfying BER values ​​described above. On the other hand, to achieve short maximum interruption time T1, it required a great deal of cost to build a circuit for sufficiently attenuate the output of the laser light within that time.
[0028]
　Moreover, in Case 2, since the maximum interruption time T2 is long, it is necessary to reduce the output P2 of the laser beam normal data transmission period, it is also reduced margin for satisfying BER values ​​described above. On the other hand, the cost of the circuit for realizing the attenuation of the laser light output in the maximum interruption time T2 is low.
[0029]
　Further, (referred to as Accessible Emission Limit, hereinafter AEL) "Class 1" and the prescribed value of the output of the laser beam in the "Class 1M", when a light of a wavelength of 700 nm ~ 1050 nm and an extended source, calculated by Equation 1 below It is. Note that Equation 2 to Equation 4, C in Formula 1 4 , C 6 , T 2 is a calculation formula of.

[0031]
　In Expression 1, lambda is the wavelength of light source used for transmission. Further, as shown in FIG. 4, A is the source size is a light emitting end face dimension of the optical connector 300, a viewing angle α is determined by measuring the distance D (70mm / 100mm / 2000mm) and source size A.
[0032]
　According to Equation 1, in order to increase the output P of the laser light depends on the length and the source size A of the wavelength lambda. When a fixed wavelength, a method of increasing the source size is the most effective. Here, the light source diameter A is, if multiple light sources are arranged in a dispersed, an average value of the aspect.
[0033]
　Figure 5 is a schematic diagram showing for each of the two arrangement example of a transmission channel Tx and the reception channel Rx of the defined range of the "Class 1" of the laser beam obtained from Equation 1, the end portion of the optical connector 300. Here, as an example, a light of a wavelength 850 nm, the optical path diameter of 0.18 mm, transmission channel 12ch, receive channel 12ch, the optical path length 100 mm, assuming an optical fiber transmission line interruption time 0.01 seconds, the connector unit 102 and connector transmission channel (Tx) and 0.25mm pitch reception channel (Rx) in the transverse direction in the part 202 shows a case in which are arranged at 1mm pitch in the vertical direction. It is not limited to the optical fiber 400 as an optical transmission line may be one which transmits light in other configurations.
[0034]
　Also shows a case where the measured distance D = 100 mm, as an arrangement of a receiving channel Rx and the transmission channel Tx, and when is densely in the central transmission channel (Tx) of (1), transmission (2) It shows when dispersed channel (Tx) in the transverse direction.
[0035]
　5, each optical fiber 400 constituting a transmission channel (Tx) and receive channel (Rx), a glass material for transmitting light is composed are coated with a resin film. As an example, the optical fiber 400 is the outermost diameter of 0.25mm, in the transverse direction are arranged in 0.25mm pitch by outermost coating is disposed in close contact with each other. Although the vertical direction is set to 1mm pitch, it may be arranged at 0.25mm pitch in the vertical direction.
[0036]
　As described above, the light source diameter A is, if multiple light sources are arranged in a dispersed, since the average value of the aspect, it was distributed transmission channel (Tx) is the source size A is increased, since the visual angle α increases, it is possible to increase the light output.
[0037]
　Therefore, as shown in FIG. 5, towards the case of a transmission channel shown in (2) (Tx) is dispersed in the lateral direction, since the source size A is increased, the output of the laser light (specified value) larger can do. Thus, the margin can be increased as shown in FIG. 2, good transmission can be performed. Specifically, if the transmission channel (2) (Tx) was dispersed in the lateral direction, when applying the above-described conditions to Formula 1, the output of the laser beam (0.6 mW). On the other hand, (1 transmitting channel (Tx) of) If is clustered in the central, the output of the laser light becomes (0.4 mW). The maximum output in the data transmission period in the case of maximum breaking time was a 0.01 [sec], if dispersed in the lateral direction transmission channel (Tx) of (2), (3.7mW), and the on the other hand, if it is clustered in the central transmission channel (Tx) of (1), and (2.5 mW).
[0038]
　Based on the above results, in the present embodiment, in the arrangement of the optical cable of the connector portion 102 and 202, by distributed transmission channel (Tx) in the lateral direction to increase the output. Thus, the margin can be increased as shown in FIG. 2, good transmission can be performed. Further, by using the APR function, it is possible to increase the output of the laser beam normal data transmission period, it is possible to increase the further margin for satisfying BER value.
[0039]
4. Channel arrangement of the connector portion
　6 are transmission channel 12ch, arrangement of the reception channel 12ch, in the connector unit 102 and connector unit 202 having an optical path of total 24ch, optical fiber 400 of the transmission channel (Tx) and receive channel (Rx) It is shown. The connector of consumer applications, in order to be mounted on devices such as mobile terminals, it is required that the size is small. In the arrangement example, in the terminal arrangement of the total 24ch, 12 pieces in the transverse direction (N = 12), by a sequence of longitudinal in two stages (M = 2), the longitudinal direction of the thickness is as thin as possible. Further, in this arrangement example, by contacting the respective outermost coating between the optical fiber 400, and the size of the connector portion 102, 202 was minimized. Here, N is the transverse direction of the number of terminals (the number of optical fibers 400), M is the longitudinal direction of the number of terminals (the number of optical fibers 400).
[0040]
　In such arrangement, in order to further free the upper and lower insertion direction of the longitudinal direction, the transmission channel (Tx) and receive channel (Rx) are arranged in point symmetry in the arrangement is a predetermined region. Thus, the optical cable 300 to the connector portion 102 and 202 (if inserted rotated 180 °) when inserted in the upside down it becomes possible to connect. As described above, in order to maximize the output of the laser light source in Equation 1, the arrangement length in the horizontal direction is set to be larger of the transmission channel (Tx), be distributed transmission channel (Tx) desirable.
[0041]
　6, when the lateral direction of the terminal number N has an even (= 12) shows a case that has densely transmit channel (Tx) in the center. Horizontal alignment length output as large transmission channels as described above (Tx) becomes large. Arrangement example shown in FIG. 6, in the arrangement of N = 12, M = 2, for placement length D in the lateral direction of the transmission channel (Tx) is the minimum, the output is the smallest arrangement of the transmission channel (Tx) is there.
[0042]
　7 to 10, in view of the above conditions, if the number of terminals transverse to an even (N = 12) (FIG. 7, FIG. 8) when the odd (N = 13) (FIG. 9, FIG. for 10), an optical fiber 400 of the transmission channel (Tx) indicates the sequence of point symmetry. 7 to 10 are each transmission channel (Tx) becomes symmetrical with respect to the center point C in the figure, the horizontal direction of the array length D of the transmission channel (Tx) is arranged to be a maximum.
[0043]
　Figure 7 shows an example of a case of performing a centralized arrangement on the left upper and right lower halves of the transmission channel (Tx). 8, the transmission channel (Tx) and receive channel (Rx) arranged laterally even number alternately shows an example of a case of performing zigzag arrangement in the upper and lower. 7 and 8 for sequence length D in the lateral direction is the same, it is possible to obtain the same light output.
[0044]
　9, the transmission channel (Tx) and receive channel (Rx) arranged transversely alternately, the vertical direction indicates an example of a case of performing the arrangement of upper and lower the same channel. In this case also the sequence length D in the lateral direction can be maximally secured. For Figure 9, the number of terminals transverse to the odd transmission channel (Tx) is the required number (in this case, 12) but are arranged two more than the arrangement length D of the transmission channel 7 and 8 longer than the case of. For Figure 9, even if obtained by reversing the sequence of the transmission channel (Tx) and receive channel (Rx), it can be arranged in the same manner, in this case, when the arrangement length D of the transmission channel (Tx) of FIG. 9 slightly shorter than the.
[0045]
　Figure 10 is a transmission channel (Tx) and receive channel (Rx) arranged transversely alternately, if the vertical direction is subjected to arrangement of the upper and lower the same channel, the arrangement of the outermost placed only vertical stage different channels It shows an example in the case of performing. For Figure 10, the receiving channel number required (in this case, 12) but are arranged two more than the arrangement length D of the transmission channel (Tx) is longer than the case of FIGS.
[0046]
　Incidentally, in the sequence of N = 12 or N = 13, M = 2, may be exemplary arrangement shown in FIGS. 7 to 10 is the longest placement length D of the transmission channel (Tx), the arrangement shown in FIG. 6 if the sequence of a long arrangement length than the length D, can be enhanced reliably light output than the arrangement shown in FIG.
[0047]
　Therefore, according to this embodiment, the user optical transceiver 100 without considering the top and bottom direction of the optical connector portion 102, 202 can be connected to the optical transceiver 200. Further, according to this embodiment, it is possible to increase the output level of the laser light source (specified value specified in the laser safety standard), it is possible to provide a large margin for the bit error rate of a transmission signal, improving the transmission quality to, can greatly increase the convenience of the user.
[0048]
5. Modification of the embodiment
　11 show a modification of the terminal arrangement of the connector portion 102, 202 of the present embodiment. In the optical fiber system 1000 of FIG. 1, as the data transmitted from the optical transceiver 100 to the optical transceiver 200, for example, video and audio data uncompressed is assumed. In this case, the transmission rate of the return channel from the optical transmitting and receiving apparatus 200 to the optical transceiver 100 is that the data transmission is performed at an extremely low transmission rate than the non-compressed video and audio data described above is envisaged. In the system of the transmission rate to be asymmetrical by such transmission direction, it becomes possible to realize the terminal arrangement shown in FIG. 11. Wherein the sequence shown on the left side of FIG. 11 is similar to FIG. 6, the sequence shown in the right side of FIG. 11 are disposed at both ends of the transmission channel (Tx) to the sequence of FIG. At this time, the transmission channel of the optical transceiver 100 arranged at both ends of the terminal (Tx) is to increase the output of the laser light source, and a margin of uncompressed video and audio data described above, arranged in the center of the terminal it may be low output of the laser light source for the return channel of the optical transceiver 200 corresponding to the reception channel (Rx).
[0049]
　According to the present embodiment as described above, the user optical transceiver 100 without considering the top and bottom direction of the optical connector portion 102, 202 can be connected to the optical transceiver 200. Further, according to this embodiment, it is possible to increase the output level of the laser light source (specified value specified in the laser safety standard), it is possible to provide a large margin for the bit error rate of a transmission signal, improving the transmission quality to, can greatly increase the convenience of the user. Thus, the connection between devices for optical transmission, the connection be changed orientation of the connector can be the result, and provides the terminal arrangement of the improvement possible connector terminal transmission quality in a safety standard regulations value required for the laser beam be able to.
