100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft)100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC
The 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) is a passive twinax direct attach copper cable with QSFP28 to SFP28, supporting 100Gbps links over a length of 0.5m (2ft). 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 100G Ethernet, data center interconnect and 5G transport networks, and complies with IEEE 802.3, QSFP28 MSA, SFF-8665.

Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) provides a factory terminated 100Gbps link between QSFP28 to SFP28 ports. This unit is stocked in 8 standard lengths from 0.5m (2ft) to 5m (16ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-4SFP25G-CU50CM directly.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3, QSFP28 MSA, SFF-8665. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-4SFP25G-CU50CM.
Ordering Information
The ordering code varies with length, such as QSFP-100G-4SPC005 for the shortest option. Standard supply covers 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 3.5m (11ft) and 5m (16ft). Custom length production is available for project requirements. Wire gauge: 30AWG. Volume pricing is available for project quantities.
Packing Details
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.
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.
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.
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.
