400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC

The 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC is an active optical cable assembly with QSFP-DD to 8x 50G SFP56, carrying 425Gbps (8x 53.125GGbps) 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 and cloud network environments. This assembly comes in standard lengths from 1m (3ft) to 70m (230ft).

The 400G QSFP-DD 8x 50G PAM4 to 8x 50G SFP56 50G PAM4 Breakout AOC connects QSFP-DD to 8x 50G SFP56 ports at 425Gbps (8x 53.125GGbps) in 400G Ethernet data center and cloud network environments. This unit is stocked in 12 standard lengths from 1m (3ft) to 70m (230ft). By fanning one port out to 8x 50G SFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards compliance covers QSFP-DD MSA, SFP56 MSA, IEEE 802.3cd. The unit works in any equipment with a standard QSFP-DD to 8x 50G SFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Order reference: part number QDD-400G-8SAO. Standard supply covers 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft), 50m (164ft) and 70m (230ft). Custom length production is available for project requirements. Samples for testing can be arranged before bulk orders.

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.

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.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
