400G QSFP112 4x 100G PAM4 to QSFP-DD 8x 50G PAM4 AOC

The 400G QSFP112 4x 100G PAM4 to QSFP-DD 8x 50G PAM4 AOC connects QSFP112 to QSFP-DD ports at 400Gbps over AOC fiber at 850nm. Because the optics are built into the cable ends, installation is plug and play with no separate transceivers to manage, and airflow inside the rack stays unobstructed. It is well suited to 400G Ethernet data center and cloud network environments. Standard lengths run from 1m (3ft) to 30m (98ft).

The 400G QSFP112 4x 100G PAM4 to QSFP-DD 8x 50G PAM4 AOC is a 400Gbps active optical cable for QSFP112 to QSFP-DD connections in 400G Ethernet data center and cloud network environments. This unit is available in 10 standard lengths from 1m (3ft) to 30m (98ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs QSFP112-4x 100G-PAM4 QSFP-DD-8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards compliance covers QSFP112 MSA, QSFP-DD MSA, IEEE802.3ck, IEEE802.3bs, CMIS 5.1. The unit works in any equipment with a standard QSFP112 to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

The standard part number of this assembly is QSFP-400G-QDDAO. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft) and 30m (98ft). Custom lengths beyond this range can also be produced on request. Volume pricing is available for project quantities.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

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.
