Ascent Communication Technology

10G SFP+ CWDM 2733 10 km

Ascent’s SFPP-AT-LP-XXXX-10 transceivers are designed expressly for high-speed communication applications that require rates up to 11.3 Gb/s. They are designed to be compliant with the SFF-8472 SFP+ MSA. The module is suitable for data links up to 10 km in distance over a 9/125 µm single mode fiber. ASCENT SFP+ transceivers provide a unique enhanced digital diagnostic monitoring interface which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags which alerts end users when particular operating parameters are outside of a factory set normal range.
