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 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.

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 supplied 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. 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.

This product is designed and tested to comply with QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd. It plugs into any standards-based QSFP-DD to 4x QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model carries part number QDD-200G-4QPC. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Non-standard lengths can be produced on request. Wire gauge: 30 AWG. Samples for testing can be arranged before bulk orders.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

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.

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.

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.
