| The LWFTR-SFP1.25G-3012L series SFP transceiver is high performance, cost effective module supporting dual data-rateof1.25Gbps/1.0625Gbps and from 10km to 20km transmission distance with SMF.
The transceiver consists of two sections: The transmitter section incorporates a FP laser. And
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 is
provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to
indicate the loss of an input optical signal of receiver.
The standard serial ID information compatible with SFP MSA describes the transceiver’s
capabilities, standard interfaces, manufacturer and other information. The host equipment can
access this information via the 2-wire serial CMOS EEPROM protocol. For further information,
please refer to SFP Multi-Source Agreement (MSA).
The SFP transceivers are compatible with RoHS.
