Applications
The 400G OSFP 4x 100G PAM4 to QSFP-DD 8x 50G PAM4 AOC, 30m is a 400Gbps active optical cable for OSFP (RHS/Flat Top) to QSFP-DD connections in 400G Ethernet data centers, HPC and machine learning clusters. This unit is produced in 10 standard lengths from 1m (3ft) to 30m (98ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, QSFP-DD MSA, CMIS 4.0, IEEE 802.3ck-400GAUI-4, IEEE 802.3bs-400GAUI-8. It plugs into any standards-based OSFP (RHS/Flat Top) to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The factory part number is QDD56-400G-O112RAO. This cable is available in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft) and 30m (98ft). Lengths outside the standard range are made to order in our factory. Volume pricing is available for project quantities.
Quality Assurance
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.
Package
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.
OEM and Custom Orders
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.
Shipping and Lead Time
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.
