[0064] refer to Figure 1 to Figure 9 The active optical cable (Active Optical Cable) according to the first embodiment of the present invention will be described.
[0065] (Structure of Active Optical Cable)
[0066] refer to figure 1 The structure of the active optical cable 1 according to this embodiment will be described. figure 1 It is a block diagram showing the structure of the active optical cable 1 .
[0067] The active optical cable 1 is a cable for realizing two-way communication between two devices, and is equipped with a composite cable 10, a first connector 11, a second connector 12, and an auxiliary connector 13 ("the second connector in the claims") An example of an auxiliary connector"), and the auxiliary cable 14. In this embodiment, the active optical cable 1 is implemented as a USB (Universal Serial Bus: Universal Serial Bus) cable. Here, the device used to connect to the first connector 11 is referred to as a “host device” 51 , and the device used to ...
Deformed example 1
[0126] In addition, in this embodiment, only when the state at the start of the operation (when the first connector 11 or the auxiliary connector 13 is connected to the host device 51) is the state 5 or the state 6 shown in the above-mentioned Table 1 , the configuration for performing the fault check has been described, but the present invention is not limited thereto. For example, only when the state at the start of the action is State 2, State 4, or State 6 shown in Table 1 above, that is, when the second connector 12 is not connected at the start of the action, A structure that implements failure checking.
[0127] exist Image 6 A modified example of the first connector 11 suitable for such a structure is shown in . Image 6 It is a block diagram showing the internal structure of the first connector 11A according to this modification.
[0128] The first connector 11A according to this modified example is a pair of figure 2 The first connector 11 shown is a connector ...
Deformed example 2
[0132] In Modification 1 described above, the configuration in which the failure inspection is performed only when the second connector 12 is not connected at the start of the operation has been described. In this case, the active optical cable 1 does not necessarily have the auxiliary connector 13 and the auxiliary cable 14 . A modified example of the active optical cable 1 without the auxiliary connector 13 and the auxiliary cable 14 is referred to as the active optical cable 1B in Figure 7 shown in . In such a configuration, when the active optical cable 1B is connected to the first connector 11 but not connected to the second connector 12 , it is only necessary to perform a fault inspection.
[0133] Figure 8 It is a block diagram showing the internal structure of the first connector 11B included in the active optical cable 1B.
[0134] The first connector 11B involved in this modified example is a slave Image 6 The illustrated first connector 11A omits the structur...
