Applications
The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Passive Breakout DAC Cable, 2m is a 400Gbps direct attach copper cable for QSFP-DD to 4x QSFP56 connections in 400G Ethernet data center and cloud network environments. This unit is delivered in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 4x QSFP56, 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.
Standards and Compatibility
This product is designed and tested to comply with SFF-8665, QSFP-DD MSA, IEEE802.3bj, IEEE802.3 cd. It plugs into any standards-based QSFP-DD to 4x QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The ordering part number is QDD-400G-4QPC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
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.
