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 supplied 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 model carries part number QSFP-40G-1SPC01-GENERIC-2. You can order this assembly in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Non-standard lengths can be produced on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

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.

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.
