Cisco Compatible Fiber Optic Cable 25G SFP28 AOC Active Optical Cable
Description
Cisco Compatible 1 to 100 Meters 25G SFP28 AOC Active Optical Cable manufactured by ANC International Co., Limited is direct-attach fiber assemblies with SFP28 connectors. They are suitable for very short distances and offer a cost-effective way to connect within racks and across adjacent racks.
The 25G SFP28 AOC cable is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25 Gigabit Ethernet and Infiniband EDR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector.
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. Rigorous production testing ensures the best out-of-the-box installation experience, performance, and durability.
