100GBASE-SR4 100m 带/不带 FEC or 300m 带FEC QSFP28光模块 - 北亿纤通|F-tone Networks-全球光芯片光器件光模块光通信系统产品领导者!

Description
The F-tone Networks FTQ2-HG-SR4 is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 SR4 for 100 or 40 Gigabit Ethernet and Infiniband FDR/EDR Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. Each lane can operate at 25.78125Gbps up to 70 m using OM3 fiber 100m using OM4 fiber w/o FEC or 300m OM4 MMF with KR-FEC. 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.

Features
● Hot-pluggable QSFP28 form factor
● 4 channels full-duplex transceiver module
● Supports 4*25.78125Gb/s bit rate
● 4 channels 850nm VCSEL array
● 4 channels PIN photo-detector array
● Internal CDR circuits on both receiver and transmitter channels
