QSFP+ to SFP+-40G-DAC-3M10FT 40G QSFP+ to 1 x 10G SFP+ Passive Copper Cable, 3m (10ft)

This 3m (10ft) DAC cable is built for multi-vendor equipment requiring the QSFP+ to SFP+-40G-DAC-3M10FT interface. The 40Gbps link uses QSFP+ to SFP+ and is supplied as one complete tested assembly.

OEM Part Number: QSFP+ to SFP+-40G-DAC-3M10FTHT Part Number: QSFP+ to SFP+-40G-DAC-3M10FT

Product Highlights

• HT-manufactured DAC assembly in 3m (10ft)
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 3m (10ft), QSFP+ to SFP+-40G-DAC-3M10FT
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: 0.1W Per End
• Minimum bend radius: 28mm

The rated power consumption is 0.1W Per End. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8636, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

QSFP+ to SFP+-40G-DAC-3M10FT occupies the middle of this family between QSFP+ to SFP+-40G-DAC-2M7FT at 2m (7ft) and QSFP+ to SFP+-40G-DAC-5M16FT at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 28mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The assembly is configured for equipment that recognizes QSFP+ to SFP+-40G-DAC-3M10FT. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Use part number QSFP+ to SFP+-40G-DAC-3M10FT for the 3m (10ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
