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.
