QSFP+ to SFP+-40G-DAC-1M3FT 40G QSFP+ to 1 x 10G SFP+ Passive Copper Cable, 1m (3ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 1m (3ft) cable run. It corresponds to Generic QSFP+ to SFP+-40G-DAC-1M3FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

Product Highlights

• HT-manufactured DAC assembly in 1m (3ft)
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 1m (3ft), QSFP+ to SFP+-40G-DAC-1M3FT
• 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.

At 1m (3ft), QSFP+ to SFP+-40G-DAC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

QSFP+ to SFP+-40G-DAC-1M3FT occupies the middle of this family between QSFP+ to SFP+-40G-DAC-0.5M2FT at 0.5m (2ft) and QSFP+ to SFP+-40G-DAC-2M7FT at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 1m. 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 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.

The HT cable carries the compatibility configuration associated with QSFP+ to SFP+-40G-DAC-1M3FT, while its mechanical assembly remains the fixed 1m (3ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

Use part number QSFP+ to SFP+-40G-DAC-1M3FT for the 1m (3ft) 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.

Every QSFP+ to SFP+-40G-DAC-1M3FT compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1m (3ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
