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. The standard lineup covers lengths from 1m (3ft) to 50m (164ft).

Designed for 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Breakout AOC, 30m carries 400Gbps between QSFP-DD to 4x QSFP56 interfaces. This unit is manufactured in 10 standard lengths from 1m (3ft) to 50m (164ft). One port becomes 4x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs QSFP-DD-8x 50G-PAM4 QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Part number of this model: QDD-400G-4QAO. Length options are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 25m (82ft), 30m (98ft) and 50m (164ft). Our factory also produces custom lengths beyond these on request. Volume pricing is available for project quantities.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.
