The 40G QSFP+ Passive DAC, 1m (3ft) is a twinax direct attach copper cable with QSFP+ to QSFP+, supporting 40Gbps links over a length of 1m (3.28ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 40G Ethernet data center and enterprise network environments, and complies with SFF-8436, QSFP+ MSA and IEEE 802.3ba.

Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Passive DAC, 1m (3ft) provides a factory terminated 40Gbps link between QSFP+ to QSFP+ ports. This unit is offered in 7 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. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-H40G-CU1M directly.
Standards and Compatibility
Compliance: SFF-8436, QSFP+ MSA and IEEE 802.3ba. For projects standardized on Cisco hardware, this product replaces the QSFP-H40G-CU1M directly, with identical fit and function. 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.
Ordering Information
Order this assembly under part number QSFP-40G-PC01. Available lengths are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). If you need a length outside this list, our factory can build it to order. Wire gauge: 30AWG.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Packaging
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.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
