ASCENT’s SFP+ transceiver SFPP-ATLP-31-40 is designed for use in 10-Gigabit Ethernet links up to 40km over single mode fiber. The module consists of 1310 DFB Laser, PIN and Preamplifier in a high-integrated optical sub- assembly. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF¬8472. The module data link up to 40km in 9/125um single mode fiber. The 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.

1. The transceivers provide serial ID memory contents and diagnostic information about the present
operating conditions by the 2-wire serial interface (SCL, SDA). The diagnostic information with internal
calibration or external calibration all are implemented, including received power monitoring, transmitted
power monitoring, bias current monitoring, supply voltage monitoring and temperature monitoring.
