A pluggable SFP28 optical transceiver is designed for use in 25GbE Ethernet. It incorporates Mellanox integrated circuit technology in order to provide high performance at low power. The transceiver operates over a pair of multi-mode fibers (MMF), using a nominal wavelength of 850nm, and is SFF-8402 compliant.
Standard SFP28 connector on the electrical side towards the host system supporting IEEE 802.3bm. The optical interface is composed of two optical channels/fibers, one in each direction, intended for a multi-mode optical cable connected via standard LC connectors. Each channel/fiber operates at signaling rates up to 25.78125GBd.
The transceiver offers selectable retiming for both its optical transmitter and receiver for the 25Gb/s rate, and it also supports lower bit rates without. The transmitter has programmable input equalizers and input squelch function, while the receiver has programmable output amplitude and pre-emphasis. Rigorous production testing ensures the best out-of-the-box installation experience, performance, and
durability.
