25G SFP28 Passive DAC

For short reach 25Gbps links in 25G Ethernet, data center interconnect and 5G transport networks, the 25G SFP28 Passive DAC, 0.5m (2ft) offers a factory terminated passive twinax assembly with SFP28 to SFP28 connectors and a length of 0.5m (1.64ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000.

The 25G SFP28 Passive DAC, 0.5m (2ft) is a 25Gbps direct attach copper cable for SFP28 to SFP28 connections in 25G Ethernet, data center interconnect and 5G transport networks. 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

Compliance: IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000. 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 SFP-25G-PC005 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), 4m (13ft) and 5m (16ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

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.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
