Description Application

The SFBD-1250xxxx series are 3.3V small IEEE 802.3ah 1000BASE-BX10-U

Form Factor Bi-Directional Transceiver Module designed expressly for high-speed

GE-Media Converter communication applications that require rates of Gigabit Ethernet P2P Optical Network up to 1.25Gbit/sec. It is compliant with the

Gigabit Ethernet standards, as well as the SFF

Multisource Agreement (MSA).

FTTx WDM Broadband Access

The module consists 1310nm FP laser,

InGaAs PIN, Preamplifier and WDM filter in a SFBD-1250A4Q1R data link up to 10km in

9/125um single mode fiber. high-integrated optical sub-assembly, and it is contained in a standard SFF package with a

9/125um SC receptacle connector.
