100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft)
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
The 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) connects QSFP28 to SFP28 ports at 25Gbps in 100G Ethernet, data center interconnect and 5G transport networks. This unit is made in 4 standard lengths from 1m (3ft) to 5m (16ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
This product is designed and tested to comply with QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. It plugs into any standards-based QSFP28 to SFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The part number for this assembly is QSFP-100G-1SPC01. We offer this cable in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Other lengths can be custom manufactured on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.
Tested Before Shipment
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.
Packaging Options
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.
OEM and Custom Orders
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.
Worldwide Delivery
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.
