Single-fiber transceivers and Dual-fiber transceivers

Single-fiber transceivers and Dual-fiber transceivers

 

With the rapid development of the Internet, the transmission distance of the twisted pair and the influence of electromagnetic interference are limited, which restricts the development of the network. Therefore, the optical transceiver has emerged.

The use of fiber optic transceivers replaces the connection medium in the Ethernet with fiber.

A fiber optic transceiver is a photoelectric conversion device that converts an Ethernet electrical signal and an optical signal to each other.

By converting an electrical signal into an optical signal and transmitting it on a multimode or single mode fiber, the optical cable has a short transmission distance limit,

so that the Ethernet Under the premise of ensuring high-bandwidth transmission, the network uses fiber-optic media to achieve long-distance transmission of several kilometers or even hundreds of kilometers.

When the optical transceiver is embedded in the optical transceiver, the optical transceiver is divided into a single-fiber transceiver and a dual-fiber transceiver according to the number of cores of the connected optical fiber jumpers.

The linearity of the fiber jumper connected to the single-fiber transceiver is a core, which is responsible for transmitting data and receiving data;

and the fiber jumper connected to the dual-fiber transceiver has two cores, wherein One core is responsible for transmitting data and the other core is responsible for receiving data.

When the optical transceiver does not have an embedded optical module, it needs to distinguish whether it is a single-fiber transceiver or a dual-fiber transceiver according to the inserted optical module.

When a single-fiber bidirectional optical module is inserted into the optical transceiver, that is, the interface is a simplex type, the optical transceiver is a single-fiber transceiver; when the optical transceiver is inserted into a dual-fiber bidirectional optical module, the interface is dual This type of transceiver is a dual-fiber transceiver.
