800G QSFP-DD AOC Cable

Teosco 800G QSFP-DD Active Optical Cable (AOC) is a high-quality optical cable designed for utilization in 800 Gigabit Ethernet links over 50 meters on OM4 MMF. Each end of AOC modules features 8 independent electrical input/output channels operating at 106.25Gbps per channel. Each of AOC modules consists of two transmitter/receiver units. The transmitter path of the module incorporates a bi-directional PAM4 re-timer ASIC integrated with two 4-channel drivers, 8 externally modulated lasers. On the receiver path,8 photodiodes and two 4-channel TIAs are used, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 800GAUI-8 interface as defined by IEEE 802.3ck, and compliant with QSFP-DD800 MSA. It features low latency, superior signal integrity and energy efficiency, making them ideal for applications of high-density, high-performance data centers and cloud computing.
