SFP transceiver
SFP transceiver,SFP modules
Product Name:SFP transceiver
The SFP transceiver supports dual data-rate of 1.25Gbps/1.0625Gbps and up to 120km transmission distance with single-mode fiber or 550m with multi-mode fiber.
The transceiver consists of two sections: The transmitter section incorporates a FP or 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 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)
