100G QSFP28 to 25G SFP28 AOC active optical cables are used for 100G (100GBASE-SR4) to 4-way 25G (25GBASE-SR) Ethernet branch links in data centers. At the same time, they are 100% perfectly compatible with a full range of branded servers, switches, routers, PDH/SDH transmission equipment, EPON, GPON, WDM PON base stations, and other equipment. Through OM3 multimode fiber (MMF), interconnections up to 100m can be achieved, with high reliability, low cost, and low power advantages.
