Description

The SFBD-1250xxxx series are 3.3V small

Form Factor Bi-Directional Transceiver Module

designed expressly for high-speed communication

applications that require rates of up to

1.25Gbit/sec. It is compliant with the Gigabit

Ethernet standards, as well as the SFF Multisource

Agreement (MSA).

The module consists multiple quantum well

laser, InGaAs PIN, Preamplifier and WDM filter in a

high-integrated optical sub-assembly, and it is

contained in a standard SFF package with a

9/125um SC receptacle connector.

Application
