Today to talk about the type of optical module interface
The optical device is an optical module may transmit and receive an analog signal. Electrical signal by the transmitting end of the optical module into an optical signal, and then through the receiving end converts the optical signals into electrical signals in order to achieve a photoelectric conversion.
To get them to realize the exchange of information, it is necessary to connect the two modules light up, then you need a matching interface.
Shown, an optical module 40G QSFP 10G SFP optical module 4 is connected as shown below, to be connected with the MPO-4DLC fiber jumpers.
Interface Type
MPO optical module describes the interfaces, the interface duplex LC, LC single core, and RJ-45 interface.
MPO optical module Interface
MPO optical module has an interface QSFP28 optical module, the optical module of CFP2, QSFP + optical module using MPO / M (female) connector, as shown below:
LC duplex optical module Interface
The interface module has an optical LC duplex optical module QSFP28, the CFP optical module, the optical module of CFP2, QSFP + optical module, SFP28 optical module, SFP + optical module, SFP optical module using LC duplex connector, as shown below:
LC connector single-core optical module
LC Interface for the single-core optical module BIDI optical module is worth one BIDI optical module must be used in pairs. LC single core connector as shown below:
RJ-45 interface optical module
RJ-45 interface optical module is the optical module electrical interface, connector using twisted pair, as compared to optical transmission, a twisted pair transmission distance is small, only applicable to small-sized networks.
