40G QSFP+ to 1x10G SFP+ Passive DAC

The 40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft) is a passive twinax direct attach copper cable with QSFP+ to SFP+, supporting 40Gbps 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 40G Ethernet data center and enterprise network environments, and complies with SFF-8636, SFF-8472.

The 40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft) connects QSFP+ to SFP+ ports at 40Gbps in 40G Ethernet data center and enterprise network environments. This unit is provided in 6 standard lengths from 0.5m (2ft) to 7m (23ft). 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 compliance covers SFF-8636, SFF-8472. The unit works in any equipment with a standard QSFP+ to SFP+ interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This assembly is listed under part number QSFP-40G-1SPC01-GENERIC-2. The cable is supplied in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond the standard range are available on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.

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.

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.

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.

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.
