Description Review
Product Overview
The SFP-GQS-MPO400-SR4T is a Four-Channels, Pluggable, Parallel, Fiber-Optic QSFP form factor for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnection applications. It integrates four data lanes in each direction with 4x10.3125Gbps bandwidth. Each lane can operates at 10.3125Gbps up to 100 m using OM3 fiber or 150 m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The optical interface uses a 12 fiber MTP (MPO) connector. This module incorporates LYCOM Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service
