10Gtek QSFP+ AOC is an assembly of 4 full-duplex lanes

enable deployment of additional ports for increased number of AOCs per system, resulting in more connectivity options and total system cost savings. Optical pluggable QSFP+ MTP? cable assemblies are available in 12-fiber 3.00mm round cable and a robust 4.50mm round cable. Loopbacks feature a compact housing compatible with module spacing and loop optical transmit ports to receive ports for testing, burn-in and field troubleshooting. QSFP+ AOC cables are available in  standard lengths up to 300m and  custom lengths up to 4km (2.49 miles)
for design flexibility QSFP active optical 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-SR4.10Gtek 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.The FCI QSFP+ FDR, 56Gb/s, Active Optical Cable series provides a cost effective, high performance, plug & play solution. The AOC features optical engines inside both cable connectors improving speed and distance versus traditional copper assemblies.3M’s new QSFP+ active optical cable assembly provides high-speed transmission over 100 meters of multimode fiber for high-performance computing and other ultra high-throughput networking environments.
