Specifications

            4.25G CWDM SFP Optical Transceiver, 40km Reach

Description

 The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated
with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser
safety requirements.
The transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement
(MSA)1. They are compatible with Fibre Channel per FC-PI-2 Rev. 10.0. also simultaneously
compatible with Gigabit Ethernet as specified in IEEE Std 802.3.

Digital Diagnostic Memory Map
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.
The digital diagnostic memory map specific data field defines as following.
