25G SFP28 Passive DAC

The 25G SFP28 Passive DAC, 0.5m (2ft) provides a 25Gbps copper connection between SFP28 to SFP28 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 25G Ethernet, data center interconnect and 5G transport networks.

Product Highlights

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 provided 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

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.

The part number varies by length, e.g. SFP-25G-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), 4m (13ft) and 5m (16ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

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.

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.

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.
