GIGALIGHT 25G SFP28 SR optical transceiver modules are used for short-distance interconnections between equipment within data centers or for 5G pre-transmission, and are compliant with the IEEE 802.3by 25GBASE-SR Ethernet transport protocol, with an optional dual-rate version compatible with CPRI Option 10 and 25GE. The series uses 1 pair of multimode fiber optic transmission with a central wavelength of 850nm for distances up to 70m (OM3) or 100m (OM4), with an optional industrial grade operating temperature range.
