1.25Gbps CWDM SFP Optical LC 120km Transceiver/With Digital Diagnostic Monitoring

Specifications

    1.25G CWDM SFP Optical Transceiver, 120km Reach

Description

The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps

and 120km transmission distance with SMF.

The transceiver consists of three sections: an uncooled CWDM DFB laser transmitter, a APD

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 SFP Multi-Source Agreement (MSA) and SFF-8472. For further
information, please refer to SFP MSA.

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.
