40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft)

The 40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft) provides a 40Gbps copper connection between QSFP+ to SFP+ ports with a cable length of 1m (3ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 40G Ethernet data center and enterprise network environments.

The 40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft) is a 40Gbps direct attach copper cable for QSFP+ to SFP+ connections in 40G Ethernet data center and enterprise network environments. This unit is available in 6 standard lengths from 0.5m (2ft) to 7m (23ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Compliance: SFF-8636, SFF-8472. 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.

The standard part number of this assembly is QSFP-40G-1SPC01-GENERIC-2. We supply this cable in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.

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.

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.

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.

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.
