2x100GBASE-SR4 QSFP-DD光模块

Description
The F-tone Networks Technologies FTQD-2H-SR4xx is a Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP Double Density for 2×100 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates eight data lanes in each direction with 8×25.78125Gbps bandwidth. Each lane can operate at 25.78125Gbps up to 70 m using OM3 fiber or 100 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 76 contact edge type connector. The optical interface uses an 24 fiber MTP (MPO) connector. This module incorporates F-tone Networks Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
