Description

NVIDIA/Mellanox Compatible 1.6T 2xDR4/DR8 InfiniBand XDR Silicon Photonics Optical Transceiver Module(Twin-port OSFP, 1310nm, 500m (OS2) , Dual MPO-12/APC, DOM, for SMF, Finned Top)

NADDOD OSFP-1.6T-2xDR4H Optical Transceiver Module is an InfiniBand and Ethernet 1.6Tb/s 2x800Gb/s Twin-port OSFP, 2xDR4/DR8 single mode, Silicon photonics-based, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 800Gb /s each. The parallel single mode, data center reach 8-channel (2xDR4/DR8) design uses 200G-PAM4 modulation and has a maximum fiberreach of 500-meters using 8 single mode fibers. The main application for OSFP-1.6T-2xDR4H is linking two switches together with up to 500 meters.

Questions & Answers

Ask a Question

Is the IB 1.6T 2xDR4 optical module compatible with the NVIDIA QM9700 switch?

No, because there is a mismatch in the serdes rates. The QM9700 has an 8x100G serdes, where as the 1.6T 2xDR4 module has an 8x212G serdes, making it incompatible for use.

I am using a 1.6T module on the Quantum-X800 Q3400 device, connected to an 800G 2xDR4 on the QM9700 switch with 1:2 MPO-12/APC SMF single-mode patch cable, to achieve 1.6T-2x800G rate interconnection. Is this possible?

No, the 800G 2xDR4 optical module uses 100G-PAM4/lane, while the 1.6T 2xDR4 optical module use 200G-PAM4/lane. The channel signal rates are mismatched,they cannot be interconnected.

What are the main applications of high-speed 1.6T optical modules?

They are used to expand AI clusters in data centers, promoting the industry's transition to a network architecture of 51.2Tbps per RU.
