100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft)100G QSFP28 4x 25G NRZ Passive DAC
The 100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft) provides a 100Gbps copper connection between QSFP28 to QSFP28 ports with a cable length of 0.5m (1.64ft). 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 100G Ethernet, data center interconnect and 5G transport networks.

Applications
The 100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft) is a 100Gbps direct attach copper cable for QSFP28 to QSFP28 connections in 100G Ethernet, data center interconnect and 5G transport networks. This unit is manufactured in 7 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-100G-CU0.5M.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-CU0.5M and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8662, IEEE 802.3.
Ordering Information
The part number is length dependent, such as QSFP-100G-PC005 for the shortest option. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft) and 5m (16ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
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.
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.
