QSFP+ to SFP+-40G-DAC-5M16FT 40G QSFP+ to 1 x 10G SFP+ Passive Copper Cable, 5m (16ft)

Designed for hosts that recognize QSFP+ to SFP+-40G-DAC-5M16FT, this QSFP+ to SFP+ cable delivers 40G transmission over a fixed 5m (16ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

Product Highlights

• HT-manufactured DAC assembly in 5m (16ft)
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 5m (16ft), QSFP+ to SFP+-40G-DAC-5M16FT
• 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.

QSFP+ to SFP+-40G-DAC-5M16FT occupies the middle of this family between QSFP+ to SFP+-40G-DAC-3M10FT at 3m (10ft) and QSFP+ to SFP+-40G-DAC-7M23FT at 7m (23ft). It adds 2m 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 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 5m (16ft) length gives QSFP+ to SFP+-40G-DAC-5M16FT more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

Each QSFP+ to SFP+-40G-DAC-5M16FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

When ordering, specify QSFP+ to SFP+-40G-DAC-5M16FT, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
