Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) provides a factory terminated 40Gbps link between QSFP+ to SFP+ ports. This unit is made in 5 standard lengths from 1m (3ft) to 7m (23ft). 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 and Compatibility
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.
Ordering Information
Part numbers differ by length, for example QSFP-40G-1SPC005 at the shortest length. We offer this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Other lengths can be custom manufactured on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.
Factory Custom Capability
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.
Delivery
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.
Tested Before Shipment
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.
Packaging Options
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.
