Description
The F-tone Networks Technologies FTQ2-DxxHG-PSMLR4xx is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 PSM4 for 100G or 40 Ethernet Metro-Access over DWDM applications. The transceiver is a high performance module for data communication and interconne ctapplicatio ns. It integrates four data lanes in each direction with 104 Gbps bandwidth. Each lane can operate at 26Gbps up to 120km over G.652 SMF with external Mux/Demux, EDFA,CD compensation. The electrical interface uses a 38 contact edge type connector. The optical interface uses a 12 fiber MTP (MPO) connector. This module incorporates F-tone Networks Technologies proven circuit and Optical technology to provide reliable long life, high performance, and consistent service.
