Product Description

1.25G STM-1/OC-3 Bi-directional SFP Transceiver


Product Description:

This SFP Transceiver Module is designed to meet the increasing demand for high capacity and high speed data transmission. It offers a high-performance, low-power 25G data link over a single mode fiber (SMF) with a transmission distance up to 15km. It adopts LC connector interface and supports hot-pluggable operation, making it easy for users to install and maintain. It is designed with a single 3.3V power supply and TTL logic interface, and is compliant to the SFP MSA standard and IEEE802.3. Furthermore, it is equipped with digital diagnostic monitoring interface (DDMI), which allows real-time monitoring of the module's operating parameters.
