25Gbps SFP28 Transceiver, Multi Mode, 100m Reach - 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 SFP28 transceivers are high performance, cost effective modules supporting data rate of 25.78Gbps over multimode fiber.The transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.
