Small Form Factor Pluggable Transceivers

Figure-1 SFP Transceivers

SUN Telecom’s SFP (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 are fully compliant with the SFP MSA (Multisource Agreement) specifications, and specially designed to support SONET, Ethernet, Fiber Channel, and other communications standards.

This transceiver supports dual data-rate of 1.25Gbps/1.0625Gbps and transmission distance up to 120km with SMF (Single-mode Fiber) or 550m with MMF (multi-mode fiber). The SFP Transceivers consist of two sections: The transmitter section incorporates a FP laser or a DFB laser, while the receiver section consists of a PIN photodiode integrated with a TIA (trans-impedance preamplifier ).

All modules in the SFP Transceivers 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.

The SFP Transceivers is compatible with Cisco, Huawei, Juniper, H3C, Broadcom, ZTE switch, etc.
