Applications
The 400G QSFP-DD QDD PC Passive DAC, 0.5m is a 400Gbps direct attach copper cable for QSFP-DD to QSFP-DD connections in 400G Ethernet data center and cloud network environments. This unit is made in 6 standard lengths from 0.5m (2ft) to 3m (10ft). 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. The link runs 8x 50Gbps PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0. 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.
Ordering Information
The part number for this assembly is QDD-400G-PC. We offer this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Other lengths can be custom manufactured on request. Wire gauge: 30AWG.
Packing Details
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.
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.
Worldwide Delivery
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
