Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x10G SFP+ Passive DAC, 1m (3ft) provides a factory terminated 40Gbps link between QSFP+ to SFP+ ports. This unit is delivered in 6 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
This product is designed and tested to comply with SFF-8636, SFF-8472. It plugs into any standards-based QSFP+ to SFP+ port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The ordering part number is QSFP-40G-1SPC01-GENERIC-2. We make this cable in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Special lengths outside this range can be produced to order. Wire gauge: 26AWG. Volume pricing is available for project quantities.
OEM and Custom Orders
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.
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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
