The 40G QSFP+ to 4x10G SFP+ Active Breakout DAC, 1m (3ft) is a 40Gbps active copper cable for QSFP+ to SFP+ connections in 40G Ethernet data center and enterprise network environments. This unit is available in 5 standard lengths from 1m (3ft) to 9m (29ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-4X10G-AC1M directly.

Compliance: SFF-8431, SFF-8432, SFF-8472 SFP+ MSA, SFF-8436 QSFP+ MSA. For projects standardized on Cisco hardware, this product replaces the QSFP-4X10G-AC1M 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.

The standard part number of this assembly is QSFP-40G-4SAC01. We supply this cable in 1m (3ft), 3m (10ft), 5m (16ft), 7m (23ft) and 9m (29ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk 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.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
