155Mbps 40KM SFP Optical Transceiver

Specifications

    155Mbps SFP Optical Transceiver, 40km Reach

Description

The SFP transceivers are high performance, cost effective modules supporting 155Mbps data-rate and 40km transmission distance with SMF.  

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 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.
