The 200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable, 0.5m is a twinax direct attach copper cable with QSFP-DD to 4x QSFP28, supporting 200G 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 200G Ethernet data center and cloud network environments, and complies with QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd.

Applications
Designed for 200G Ethernet data center and cloud network environments, the 200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable, 0.5m carries 200G between QSFP-DD to 4x QSFP28 interfaces. This unit is offered in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 4x QSFP28, 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. The link runs NRZ modulation, which keeps it aligned with current 200G switch silicon.
Standards and Compatibility
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.
Ordering Information
Order this assembly under part number QDD-200G-4QPC. Available lengths are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). If you need a length outside this list, our factory can build it to order. Wire gauge: 30 AWG. Volume pricing is available for project quantities.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Tested Before Shipment
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.
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
