Description
The Veivot optical transceiver module VV-Q28-SR4 is a 4x25Gbps multimode fiber hot swappable optical transceiver. This module integrates four parallel channels, each with a data rate of 25.78Gbps. It can transmit 70 meters on fiber optic OM3 fiber or 100 meters on OM4 fiber with FEC. This transceiver is a high-performance module used for data communication and interconnection applications. It integrates four data channels in each direction with a bandwidth of 103.1Gbps.
This module is designed to operate on a multimode fiber system with a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses a 8 core or 12 core MPO connector.
