Applications
In 400G Ethernet data center and cloud network environments, the NVIDIA InfiniBand Compatible 400G QSFP112 DR4 Optical Transceiver delivers 425Gbps (4x106.25Gb/s) transmission over SMF with a reach of 500m. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP112 MSA, CMIS 5.0, IEEE Std 802.3ck. It plugs into any standards-based QSFP112 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this product as QSFP112-DR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
