Can QDD-800G-2xDR4 module be interconnected with single port 800G DR8 module?

No. DR8 is a single 8x100G link (usually using MPO-16), the physical interface structure is not the same and cannot be interconnected.

Description

NVIDIA/Mellanox Compatible 800GBASE-2xDR4 PAM4 1310nm 500m Dual MTP/MPO-12 APC SMF Finned Top Optical Transceiver Module

NADDOD NVIDIA/Mellanox compatible QDD-800G-2xDR4 is an 800G QSFP-DD optical transceiver based on PAM4 modulation, integrating two independent 400G DR4 optical channels within a single module. Each 400G channel delivers 4×100G PAM4 transmission over an MPO-12 interface, enabling an aggregate throughput of 800Gb/s.

Designed for switches with 800G QSFP-DD ports, the QDD-800G-2xDR4 supports flexible connectivity to either a native 800G optical module or two 400G DR4 QSFP-DD modules using MPO-12 APC fiber cabling, making it well suited for high-density data center and AI network deployments.

Questions & Answers

Ask a Question

Is this module compatible with OSFP optical modules?

Yes, it can be compatible with OSFP-800G-2xDR4 module to achieve 800G transmission, and two MPO-12 APC patch cords can be used with OSFP-400G-DR4 module to interconnect 800G and 400G devices.

Does the module support one-part-two applications? How to realize it?

Yes, each MPO-12 port is connected to one 400G DR4 module, which can realize the connection of one 800G device to two 400G devices.

If only one of the MPO-12 ports is used, will it affect the module operation?

No, the module can support part of the channel work, it is feasible to connect only one of the MPO-12 ports (a 400G DR4 link), but the total rate will be reduced to 400G.

We purchased four 800G modules for a new project test. Within a 200m transmission distance, all indicators are within reasonable ranges. We plan to test longer distances next and anticipate no issues.
