Accelight AAOCQP40C-xxx is a Quad Small Form-factor, hot-pluggable parallel AOC designed for use in 40 Gbps links. It is compliant with the industry standard SFF8636, QSFP+ MSA and IEEE 802.3bm 40GBASE-SR4. The module on each end incorporates 4 full-duplex lanes including 4 independent 850nm VCSEL based transmitters and 4 independent receivers using PIN photo detectors inside. Each lane can operate up to 11.1 Gbps. The cable length is available up to 150m using OM4 fibers. The AOC module uses a 38-contact electrical edge connector. Integrated with digital diagnostic monitors accessible via a Two Wire Serial interface (I2C), it is suitable for high speed short-reach data center and cloud computing interconnects.
