200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable

For short reach 200G links in switch to switch and switch to server links within racks and across adjacent racks, the 200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable, 0.5m offers a factory terminated twinax assembly with QSFP-DD to 4x QSFP28 connectors and a length of 3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd.

Product Highlights

• QSFP-DD to 4x QSFP28
• Data rate: 200G
• Length: 6 standard options from 0.5m (2ft) to 3m (10ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

This passive breakout DAC fans one 200G QSFP-DD port out to four 50G QSFP28 ports over twinax copper, with this model at 0.5m for in-rack use. It suits dense server access where one high-radix port feeds four 50G endpoints without any optical components.

Standards compliance covers QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd. The unit works in any equipment with a standard QSFP-DD to 4x QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

The standard part number of this assembly is QDD-200G-4QPC. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30 AWG. Volume pricing is available for project quantities.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
