Applications
Description
QSFP active optic cables are a high performance, low power consumption, long reach interconnect solution supporting InfiniBand FDR/QDR/DDR/SDR,16G/10G/8G/4G/2G fiber channel , PCIe and SAS. It is compliant with the QSFP MSA and IEEE P802.3ba 40GBASE-SR4. F-toneQSFP AOC is an assembly of 4 full-duplex lanes, where each lane is capable of transmitting data at rates up to 14.025Gb/s, providing an aggregated rate of 56Gb/s.
AOC is one kind of parallel transceiver. VCSEL and PIN array package is key technique, through I2C system can contact with module.
