The SFP bidirectional fiber optic transceiver

The SFP bidirectional fiber optic transceiver. The Sopto SPT-PB series of Bi-Di fiber optic transceivers is a signal converter to convert the electrical signal into the optical signal in the computer network.

 

The biggest benefit of bidirectional fiber optic transceiver is to use only one (core) fiber to transmit and receive the optical signals simultaneously, which is less than the double fiber optical transceiver with a fiber so that it improves the amount of the existing fiber information transmission.

 

The SPT-PB 155M/1.25G series of adaptive bidirectional fiber optical transceiver is fully compatible with the IEEE802.3 10BaseT, IEEE802.3u 100BaseTX and 100Base-FX standards. And it has passed the test of the Ministry of Information Industry. All the technical indicators meet the network standards.

 

Since the different transmission wavelength and reception wavelength (1310nm/1550nm) of BI-DI fiber optical transceiver, it must be used in pairs. Otherwise, it will not work.

Single mode fiber and multi-mode fiber introduction

Single mode fibers do exhibit modal dispersion resulting from multiple spatial modes but with narrower modal dispersion. Single mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers. For these reasons, single-mode fibers can have a higher bandwidth than multi-mode fibers. Equipment for single mode fiber is more expensive than equipment for multi-mode optical fiber, but the single mode fiber itself is usually cheaper in bulk. A typical single mode optical fiber has a core diameter between 8 and 10.5 µm[2] and a cladding diameter of 125 µm. There are a number of special types of single-mode optical fiber which have been

Other type of fiber optic transceiver

For other features, the fiber optic transceiver also can be divided into other different class.  Some fiber optic transceiver modules are designed with DDM function, but some not. Some is used in CWDM, but some is used in DWDM or bi-direction (WDM). Most fiber optic transceiver modules supplied by SOPTO support DDMAdditionally, there is copper fiber optic transceiver. Most fiber optic transceivers supplied by SOPTO support Fibre Channel, LTE, SDH/SONET, CPRI and OBSAI applications.
