400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Breakout AOC

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. Standard lengths run from 1m (3ft) to 50m (164ft).

The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Breakout AOC, 30m connects QSFP-DD to 4x QSFP56 ports at 400Gbps in 400G Ethernet, data center interconnect and 5G transport networks. This unit is available 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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.

The standard part number of this assembly is QDD-400G-4QAO. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 25m (82ft), 30m (98ft) and 50m (164ft). Custom lengths beyond this range can also be produced on request. Samples for testing can be arranged before bulk orders.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
