SFP 1,25 Giga dual fibre, distance 120Km, avec fonction de diagnostique digital DDM
SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 120km transmission distance with SMF.
The transceiver consists of three sections: a 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.

What the DDM use for? DDM is Digital-diagnostic-monitoring which provides a user with critical information concerning the status of the transmitted and received signals.
This approach allows for better fault isolation and error detection.
