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.

Product Highlights

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 available 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. 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. Volume pricing is available for project quantities.

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.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
