SUN Telecom’s SFP Transceiver (small form-factor pluggable) or mini-GBIC input/output transceivers are compact and hot-pluggable for converting optical and electrical media; it is widely used for both data communication and telecommunication applications. Moreover, this SFP Transceiver are fully compliant with the SFP MSA (Multisource Agreement) specifications, and specially designed to support SONET, Ethernet, Fiber Channel, and other communications standards. SUNTelecom’s SFP Transceiver supports dual data-rate of 1.25Gbps/1.0625Gbps and transmission distance of 80km with SMF (Single-mode Fiber). The SFP Transceiver consist of two sections: The transmitter section incorporates a FP laser, while the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All modules in the SFP Transceiver are satisfying 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.
