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

The 40G QSFP+ Passive DAC, 1m (3ft) provides a 40Gbps copper connection between QSFP+ to QSFP+ ports with a cable length of 1m (3.28ft). 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.

Product Highlights

• QSFP+ to QSFP+
• Data rate: 40Gbps
• Length: 7 standard options from 0.5m (2ft) to 7m (23ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Passive DAC, 1m (3ft) carries 40Gbps between QSFP+ to QSFP+ interfaces. This unit is available in 7 standard lengths from 0.5m (2ft) to 7m (23ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-H40G-CU1M directly.

This product is designed and tested to comply with SFF-8436, QSFP+ MSA and IEEE 802.3ba. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-H40G-CU1M.

The standard part number of this assembly is QSFP-40G-PC01. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

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.

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.

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.
