InfiniBand Optics and Cables
800G/400G NDR and XDR-class InfiniBand optical modules, AOC and DAC cables — validated connectivity in GPU cluster interconnects.
InfiniBand optical modules, AOC and DAC cables complete the fabric interconnect between switches and NICs in GPU clusters. QSFP-DD and OSFP form factors in NDR 400G and XDR 800G classes deliver lossless, low-power connectivity.
Product Categories
- OSFP / QSFP-DD optical modules — 400G DR4/FR4 and 800G-class; MPO-16/MPO-8 interfaces
- AOC (Active Optical Cable) — integrated optics; simple and reliable over long distances
- DAC (Direct Attach Copper) — low-power copper for short in-rack links
- MPO/MTP trunk cables — ready-made trunks for high-density fabric cabling
Why Correct Interconnect Matters
An incorrect optic/DAC choice leads to higher power consumption, increased packet errors and bottlenecks. Correctly sized interconnect guarantees lossless fabric operation and predictable performance on NCCL/MPI traffic.
Compatibility and Procurement
Optic and cable selection is based on switch model, NIC model, distance and budget. Mevasis builds a compatibility matrix and validates link health (link flapping, FEC, PCS errors) during deployment.
