NVIDIA/Mellanox MMS4X50-NM Compatible 800G 2x FR4 OSFP PAM4 1310nm 2km Dual LC Duplex Finned Top SMF Transceiver
NVIDIA/Mellanox MMS4X50-NM Compatible OSFP 800G 2x FR4 OSFP PAM4 1310nm 2km DOM Two LC Duplex InfiniBand NDR Transceiver Module for SMF (Finned Top)
The 800G 2FR4 OSFP transceiver module is designed for use in 800 Gigabit Ethernet links over 2km singlemode fiber via dual LC Duplex connector. The module has 8 independent electrical input/output channels operating up to 106.25Gbps per channel, totally 850Gbps. 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 1310nm. The transmitter path of the module incorporates a bi-directional PAM4 re-timer ASIC integrated with EML Laser and two 4-channel modulator driver. On the receiver path, used 8 photodiodes and two 4-channel TIA arrays, along with the PAM4 re-timer.
