The SFP transceiver supports dual data-rate of 1.25 Gbps/1.0625 Gbps and from 80km transmission distance with SMF or 550m with MMF.

 

The transceiver consists of two sections: The transmitter section incorporates a 1550 nm DFB laser. The receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements. The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault indicates that degradation of the laser. Loss of signal (LOS) output indicates the loss of an input optical signal of receiver.

 

The standard serial ID information compatible with SFP MSA and SFF-8472 describes the transceiver’s capabilities, standard interfaces, manufacturer and other information. The host equipment can access this information via the 2-wire serial bus. For more information, please refer to SFP Multi-Source Agreement (MSA).
