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.

Product Highlights

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 supplied 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. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-4SFP25G-CU50CM.

Compliance: IEEE 802.3, QSFP28 MSA, SFF-8665. For projects standardized on Cisco hardware, this product replaces the QSFP-4SFP25G-CU50CM directly, with identical fit and function. 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 numbers vary by length, for instance QSFP-100G-4SPC005 for the shortest standard version. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 3.5m (11ft) and 5m (16ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.
