Accelight’s OSFP transceiver module is designed for use in 800 Gigabit Ethernet links over 2km single mode fiber. The module has 8 independent electrical input/output channels operating up to 106.25Gbps per channel. This transceiver consists of two transmitter/receiver units, with each operating on a set of 4 wavelengths on the ITU G.694.2 CWDM grid near 1300nm. The transmitter path of the module incorporates a bi directional PAM4 re-timer ASIC integrated with an 8 channels modulator driver, 8 externally modulated lasers and two optical multiplexers. On the receiver path, two optical demultiplexers are coupled to 8 photodiodes and two 4 channel TIA arrays, 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 OSFP MSA.
