The 800G QSFP-DD AOC (active optical cable) is a 800 Gb/s parallel active optical cable, which transmits parallel 8×100 Gb/s PAM4 signals over multi-mode fiber (MMF) cables up to 30m.It is compliant with QSFP112-DD MSA. The 800G QSFP-DD AOC cables supports eight electrical interface lanes, each of which operate in the data rate of 106.25G/s, with an overall aggregate bandwidth up to 850Gb/s. These modules of cables are designed to operate over multi-mode fiber systems using a nominal wavelength of 850nm. AscentOptics provide high performance, high density and low power 800G QSFP-DD active optical cables (AOC), which is suitable for short-range interconnection in data center, high- performance computing networks, enterprise core and distribution layers, and service provider applications.
