Description
The SFP transceivers are high performance, cost effective modules supporting data-rate of 1250 Mbps and 10km transmission distance on 9/125μm SMF.
The transceiver consists of three sections: a laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and DDMI control unit. All modules satisfy class I laser safety requirements.
The transceivers are compliant with the Small Form-Factor Pluggable (SFP) Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
