SFP transceiver

D/T is datacom/telcom. Data communication mainly includes computer video, data communication and so on. Telcom mainly includes wireless voice communication and so on.

Such products are often used in backbone networks in fiber-optic networks.

PON: PON: passive optical network. Such products are mainly used in the access network of optical network system. One of the triplex products can transmit fiber optic signals as well as analog signals.

Optical modules are mainly divided into GBIC, SFP, SFP+, XFP, SFF, CFP, etc. Optical interface types include SC and LC, etc. But now commonly used is SFP, SFP+, XFP, rather than GBIC. The reason is that GBIC is large and easy to break down. The SFPS commonly used today are smaller and cheaper.

Type: single-mode optical module is suitable for long-distance transmission; Multimode optical module is suitable for short distance transmission.

Function: optical module is used as the carrier of transmission between switch and equipment, which is more efficient and safer than transceiver.
