100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft)100G QSFP28 to 1x 25G SFP28 Passive DAC
The 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) is a passive twinax direct attach copper cable with QSFP28 to SFP28, supporting 25Gbps links over a length of 1m (3ft). 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 QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by.

Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) provides a factory terminated 25Gbps link between QSFP28 to SFP28 ports. This unit is manufactured in 4 standard lengths from 1m (3ft) to 5m (16ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
Compliance: QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. 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.
Ordering Information
Part number of this model: QSFP-100G-1SPC01. Length options are 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 26AWG.
Logistics
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.
Quality Assurance
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.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
Factory Custom Capability
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.
