800G QSFP-DD DAC enables high-bandwidth 800G links and supports 800G Ethernet rate. The QSFP-DD800 (Double Density) passive Direct Attach Copper cable contains 16 high-speed copper pairs, features 8 transmitting and 8 receiving 100Gbps PAM4 channels. It is suitable for very short range and high speed interconnections and offer a cost-effective and power-efficient way to establish a 800-Gigabit link between QSFP-DD 800G ports of switches/routers within racks and across adjacent racks. They enable higher port bandwidth, density and configurability at low cost and reduced power requirement in the data centers.

The 800G OSFP AOC is an 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 OSFP800 MSA, IEE802.3ck standards, and support CMIS4.0 The module supports eight electrical interface lanes which operate in 106.25G/s,with an overall aggregate bandwidth up to 850Gb/s. These modules are designed to operate over multi-mode fiber systems using a nominal wavelength of 850nm.
