200G QSFP56 4x 50G PAM4 to 4x 50G SFP56 50G PAM4 Passive Breakout DAC Cable

The 200G QSFP56 4x 50G PAM4 to 4x 50G SFP56 50G PAM4 Passive Breakout DAC Cable, 3m is a passive breakout dac direct attach copper cable with QSFP56 to 4x SFP56, supporting 200Gbps links over a length of 3m (10ft). 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 switch to switch and switch to server links within racks and across adjacent racks, and complies with SFF-8661, SFF-8432, IEEE 802.3bs-200GAUI-4, IEEE802.3cd-50GAUI-1, SFP-8636, SFF-8472.

Product Highlights

• QSFP56 to 4x SFP56
• Data rate: 200Gbps
• Cable type: Passive Breakout DAC

This passive breakout DAC splits one 200G QSFP56 port into four 50G SFP56 links over twinax copper, here at 3m. It connects 200G aggregation ports directly to 50G server and storage endpoints within a row, with no optics and no additional power draw.

This product is designed and tested to comply with SFF-8661, SFF-8432, IEEE 802.3bs-200GAUI-4, IEEE802.3cd-50GAUI-1, SFP-8636, SFF-8472. It plugs into any standards-based QSFP56 to 4x SFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

The standard part number of this assembly is QSFP-200G-4SPC. We supply this cable in 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG. 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.

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.

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.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
