400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC

The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m is an active optical cable assembly with QSFP-DD to 4x QSFP28, carrying 400Gbps over Breakout AOC 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 production lengths cover 1m (3ft) to 20m (66ft).

Designed for 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m carries 400Gbps between QSFP-DD to 4x QSFP28 interfaces. This unit is supplied in 8 standard lengths from 1m (3ft) to 20m (66ft). One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. 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 QSFP28-4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. 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.

This model carries part number QDD-400G-4Q4XNAO. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft) and 20m (66ft). Non-standard lengths can be produced 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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
