400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC

The 400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC 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. Cable length: Customized.

In 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC provides a factory terminated 400Gbps link between QSFP-DD to 4x QSFP56 ports. Ordered in customized lengths, it matches the actual rack geometry without slack. 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.

Standards compliance covers IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. The unit works in any equipment with a standard QSFP-DD to 4x QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This cable is built to order in customized lengths. Our part number QDD-400G-4QAOxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements.

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.

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.

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.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
