Mellanox LinkX - 25GBase-AOC direct attach cable

These Mellanox SFP28 Active Optical Cables (AOC) are designed for use in 25GbE Ethernet systems. These AOCs incorporate Mellanox integrated circuit technology in order to provide high performance at low power.

The AOC offers high port density and configurability, and a much longer reach than passive copper cables in the data centers. Since the AOC is hot pluggable, it is easy to install and replace.

The AOC has a standard SFF-8402 compliant SFP28 port on the electrical side towards the host system. It contains one fiber optic transceiver per end, operating at data rates of up to 25Gb/s.

The AOC offers selectable retiming for both its optical transmitter and receiver for the 25Gb/s rate, but it also supports lower bit rates without retiming. The transmitter has programmable input equalizers and input squelch function, while the receiver has programmable output amplitude and pre-emphasis.
