Applications
In 400G Ethernet data center and cloud network environments, the 400G QSFP112 to 400G QSFP-DD Active Optical AOC provides a factory terminated 400Gbps link between QSFP112 to QSFP-DD ports. This unit is supplied at 1m (3ft)~30m (98ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
This product is designed and tested to comply with QSFP112 MSA, QSFP-DD MSA, IEEE802.3ck, IEEE802.3bs, CMIS 5.1. It plugs into any standards-based QSFP112 to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
This model is supplied at 1m (3ft)~30m (98ft) under part number QSFP-400G-QDDAOxxx. Other lengths of the same assembly can be produced on request. Samples for testing can be arranged before bulk orders.
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.
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
