The 200G QSFP-DD to 8 x 25G SFP28 Passive Copper Breakout DAC Cable is a passive breakout dac direct attach copper cable with QSFP-DD to 8x SFP28, supporting 200Gbps links over a length of 0.5m (2ft)~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 interconnect and 5G transport networks, and complies with QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, SFF-8472.

Applications
Designed for 200G Ethernet, data center interconnect and 5G transport networks, the 200G QSFP-DD to 8 x 25G SFP28 Passive Copper Breakout DAC Cable carries 200Gbps between QSFP-DD to 8x SFP28 interfaces. This unit is supplied at 0.5m (2ft)~3m (10ft). By fanning one port out to 8x SFP28, 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 QSFP-DD-8x 25G-NRZ SFP28-25G-NRZ modulation, which keeps it aligned with current 200G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, SFF-8472. 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
This model is supplied at 0.5m (2ft)~3m (10ft) under part number QDD-200G-8SPCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG. Volume pricing is available for project quantities.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
