Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a single-fiber bidirectional optical module according to a first embodiment of the present invention. The bidirectional optical fiber module 10 includes an optical engine module 11 and a relay module 12. The optical engine module 11 comprises two sets of transceiving interfaces 111 and 112, the transceiving interface 111 comprises a receiving port 1111 and a transmitting port 1112, and the transceiving interface 112 comprises a receiving port 1121 and a transmitting port 1122. The relay module 12 is connected to the two sets of transceiving interfaces 111 and 112, and the relay module 12 includes two input/ output ports 121 and 122, where the input/output port 121 corresponds to the transceiving interface 111, and the input/output port 122 corresponds to the transceiving interface 112. The input/output port 121 is configured to transmit an internal signal sent by a transmitting port 1112 in the transceiving interface 111 to an external optical fiber, receive an external signal sent by the external optical fiber, and transmit the external signal to a receiving port 1111 of the transceiving interface 111. Similarly, the input/output port 122 is configured to transmit an internal signal sent by the transmitting port 1122 in the transceiving interface 112 to an external optical fiber, receive an external signal sent by the external optical fiber, and transmit the external signal to the receiving port 1121 of the transceiving interface 112.
In other implementation scenarios, the number of the optical engine modules 11 may be multiple, and the number of the input/output ports of the relay module 12 corresponds to the sum of the numbers of the transceiver interface sets of all the optical engine modules 11, for example, the number of the optical engine modules 11 is 2, each optical engine module 11 includes 2 transceiver interfaces, and the number of the input/output ports of the relay module 12 is 4.
In other implementation scenarios, the number of sets of transceiving interfaces included in the optical engine module 11 may be other numbers, and the number of input/output ports of the relay module 12 corresponds to the number of sets of transceiving interfaces of the optical engine, so that the input/output ports correspond to the transceiving interfaces one to one. For example, the optical engine module 11 includes 4 sets of transceiving interfaces, and the number of input/output ports of the relay module 12 is 4.
In a specific implementation scenario, the optical engine module 11 is an NGSFP/DSFP 100G SR2 module, the bidirectional optical fiber module is an SFP + module, and the number of optical interfaces required by the NGSFP/DSFP 100G SR2 module having 2 transmitting ports and 2 two receiving ports is reduced to 2 by setting the relay module 12, so as to match with 2 optical interface modules of the SFP + module. The size of the bidirectional optical fiber module 10 should be smaller than or equal to the space size of the SFP + module: 36mm 12mm 7mm, that is to say, the length of the single-fiber bidirectional optical module 10 is less than or equal to 36mm, the width is less than or equal to 12mm, and the height is less than or equal to 7 mm. Since the SFP + module further includes a PCBA (Printed Circuit Board Assembly), the size of the relay module 12 is less than or equal to 36mm 10mm 3mm, thereby leaving a space for the PCBA, that is, the length of the relay module 12 is less than or equal to 36mm, the width is less than or equal to 10mm, and the height is less than or equal to 3 mm.
In other implementation scenarios, the bidirectional optical fiber module can also be an NGSFP-DD/DSFP-DD 100G (2x50G) optical module or a 200G (2x100G), 400G (4x100G) SR4 multimode optical transceiver module.
