40G QSFP+ to 1x 10G SFP+ Passive DAC

For short reach 40Gbps links in 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) offers a factory terminated passive twinax assembly with QSFP+ to SFP+ connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets SFF-8636, SFF-8472.

The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) 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 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.

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.

Part numbers vary by length, for instance QSFP-40G-1SPC005 for the shortest standard version. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Non-standard lengths can be produced on request. Wire gauge: 26AWG.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.
