25G Ethernet, or 25Gigabit Ethernet (25GbE), is developed by IEEE 802.3 Task Force P802.3by. The IEEE 802.3by standard uses technology defined for 100Gigabit Ethernet implemented as four 25Gbps lanes (IEEE 802.3bj). Actually, 40G and 100G have already existed before the emergence of 25G. However, 25G Ethernet can provide a more convenient path to Ethernet speeds of 50G, 100G and beyond. With 25G, network operators are no longer to use 40G Ethernet (using four lanes of 10G) to migrate to 100G but using 4 lanes of 25G. The article introduces low-cost 25G AOC.
The 25G AOC consists of optical transceiver devices at both ends and composed of different length of OM3 or OM4 multimode optical fibers. The transceiver devices at both ends can provide the function of photoelectric conversion and optical transmission. This function ensures data transmission stability and application flexibility.
The 25G SFP28 AOC is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20-contact edge type connector.

What Is A 25G AOC?
25G AOC can be overcome the bandwidth limitation of traditional high-speed cable, and the 25G AOC can provide an ideal alternative solution for high-speed cable and short-distance SFP28 optical transceiver, and the signal is more complete and higher performance. It is widely used in high-speed, high-density, and low-power data center networks.The 25G AOC consists of optical transceiver devices at both ends and composed of different length of OM3 or OM4 multimode optical fibers. The transceiver devices at both ends can provide the function of photoelectric conversion and optical transmission. This function ensures data transmission stability and application flexibility.
