Description
The F-tone Networks FTCQ-4X-SR4xx is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40 Gbps bandwidth. Each lane can operate at 11.3 Gbps up to 300 m using OM3 fiber or 400 m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO) connector. This module incorporates F-tone Networks proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
