100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft)

For short reach 25Gbps links in 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) offers a factory terminated passive twinax assembly with QSFP28 to SFP28 connectors and a length of 1m (3ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by.

Designed for 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) carries 25Gbps between QSFP28 to SFP28 interfaces. This unit is available in 4 standard lengths from 1m (3ft) to 5m (16ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

Standards compliance covers QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. The unit works in any equipment with a standard QSFP28 to SFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

The standard part number of this assembly is QSFP-100G-1SPC01. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.

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.
