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

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.

Product Highlights

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

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 manufactured in 6 standard lengths from 0.5m (2ft) to 3m (10ft). The breakout design lets one high speed port feed 4x QSFP28, which raises port utilization and simplifies cabling in dense rows. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs NRZ modulation, which keeps it aligned with current 200G switch silicon.

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.

Part number of this model: QDD-200G-4QPC. 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: 30 AWG. Volume pricing is available for project quantities.

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.

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.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
