100GQSFP28有源光纜描述AOC，即ActiveOpticalFiber有源光纜

詳細(xì)介紹

100G QSFP28 有源光纜

描述

AOC，即Active Optical Fiber 有源光纜。通信過程中需要光收發(fā)器件，將電信號(hào)轉(zhuǎn)換為光信號(hào)，或?qū)⒐庑盘?hào)轉(zhuǎn)換為電信號(hào)的通信線纜，光纜兩端的光收發(fā)器提供光電轉(zhuǎn)換以及光傳輸功能。AOC主要由多模光纖、光收發(fā)器件、控制芯片、并行光模組成，傳輸速率高、傳輸距離長(zhǎng)、能耗低、使用方便，幫助通信設(shè)備享受到光傳輸?shù)木薮髢?yōu)勢(shì)。

Notes:

1. GND is the symbol for signal and supply (power) common for QSFP+ modules. All are common within the QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground plane.

2. VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown below. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP28 transceiver module in any combination. The connector pins are each rated for a maximum current of 500mA.
