The 200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable, 0.5m provides a 200G copper connection between QSFP-DD to 4x QSFP28 ports with a cable length of 3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 200G Ethernet data center and cloud network environments.

Applications
The 200G QSFP-DD 8x 25G NRZ to 4x 50G QSFP28 2x 25G NRZ Passive Breakout DAC Cable, 0.5m is a 200G direct attach copper cable for QSFP-DD to 4x QSFP28 connections in 200G Ethernet data center and cloud network environments. This unit is produced in 6 standard lengths from 0.5m (2ft) to 3m (10ft). One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. 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
Compliance: QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
The factory part number is QDD-200G-4QPC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 30 AWG. Volume pricing is available for project quantities.
Built to Your Spec
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.
Shipping and Lead Time
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.
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
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
