Description
QSFP active optic cables are a high performance, low power consumption, long reach interconnect solution supporting 40G Ethernet, fiber channel and PCIe. It is compliant with the QSFP MSA and IEEE P802.3ba 40GBASE-SR4. FEMRICE QSFP AOC is an assembly of 4 full-duplex lanes, where each lane is capable of transmitting data at rates up to 10Gb/s, providing an aggregated rate of 40Gb/s.
AOC is one kind of parallel transceiver. VCSEL and PIN array package is key technique, through I2C system can contact with module. Absolute Maximum Ratings
