The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Breakout AOC, 30m is an active optical cable assembly with QSFP-DD to 4x QSFP56, carrying 400Gbps over OM3 at 850nm. Factory terminated and tested as a complete link, it offers a lighter and more flexible alternative to discrete transceivers with patch cords for 400G Ethernet, data center interconnect and 5G transport networks. We keep 10 standard lengths ready, running from 1m (3ft) to 50m (164ft).

Applications
The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Breakout AOC, 30m is a 400Gbps active optical cable for QSFP-DD to 4x QSFP56 connections in 400G Ethernet, data center interconnect and 5G transport networks. This unit is offered in 10 standard lengths from 1m (3ft) to 50m (164ft). By fanning one port out to 4x QSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs QSFP-DD-8x 50G-PAM4 QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. It plugs into any standards-based QSFP-DD to 4x QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this assembly under part number QDD-400G-4QAO. Available lengths are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 25m (82ft), 30m (98ft) and 50m (164ft). If you need a length outside this list, our factory can build it to order.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
Worldwide Delivery
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.
