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.

Product Highlights

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 provided 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. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-CU0.5M directly. The link runs 4x 25G-NRZ to 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

This product is designed and tested to comply with QSFP28 MSA, SFF-8662, IEEE 802.3. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-CU0.5M.

The part number varies by length, e.g. QSFP-100G-PC005 at the shortest standard option. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft) and 5m (16ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
