400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable

The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable, 2m is a passive twinax direct attach copper cable with QSFP-DD to 2x QSFP56, supporting 400Gbps links over a length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636.

The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable, 2m is a 400Gbps direct attach copper cable for QSFP-DD to 2x QSFP56 connections in 400G Ethernet data center and cloud network environments. This unit is manufactured in 6 standard lengths from 0.5m (2ft) to 3m (10ft). The breakout design lets one high speed port feed 2x QSFP56, which raises port utilization and simplifies cabling in dense rows. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

Standards compliance covers IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. The unit works in any equipment with a standard QSFP-DD to 2x QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Part number of this model: QDD-400G-2QPC. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 28AWG. Volume pricing is available for project quantities.

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.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.
