CFP Transceiver models and modifications

The optical parameters of the media converter are determined by the parameters of the SFP modules installed in the corresponding slot of the media converter. The media converter supports working with various SFP modules with a supply voltage of 3.3 V and a data transfer rate of up to 1250 Mbit/s, that allows you to organize data transmission at distances from 0.5 to 120 km, both over multimode and single-mode fiber in two- or single-fiber communication lines. The analogue of this media converter for the SFP module is Planet GT-805A.
