400Gb/s QSFP-DD SR8, MPO-16/APC, 850nm 100m

10Gtek's QSFP-DD SR8 transceiver module is designed for use in 400 Gigabit Ethernet links over 70m OM3 or 100m OM4 fiber. The module has 8 independent electrical input/output channels operating at 53.125Gbps per channel. This transceiver consists of two transmitter/receiver units, with each operating on 850nm wavelength. 
The transmitter path of the module incorporates a PAM4 re-timer ASIC with two 4-channel modulator drivers and 8 modulated lasers. On the receiver path, it consists of 8 photodiodes and two 4-channel TIAs, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and compliant with QSFP-DD MSA.
