Ascent’s SFP28 25Gb/s transceiver is an integrated fiber optic transceiver that provides a high-speed serial link at signaling rates up to 25.78 Gb/s. It is a single- channel, pluggable, fiber-optic module for short-range data communication and interconnect Ethernet applications. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. It has a transmission distance of up to 300 m on OM3 and 400 m on OM4 multi-mode fibers. The optical interface uses duplex LC receptacle. This module incorporates proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service. The SFP28-25LP-85-03 module has the rate adaption and its operating temperature is ranging from 0°C~70°C for commercial usage and -40°C ~85°C for industrial usage.
