QSFP+ to SFP+-40G-DAC-0.5M2FT 40G QSFP+ to 1 x 10G SFP+ Passive Copper Cable, 0.5m (2ft)

With a fixed 0.5m (2ft) cable and QSFP+ to SFP+, the QSFP+ to SFP+-40G-DAC-0.5M2FT compatible assembly simplifies 40G deployment. It is manufactured and tested by HT for multi-vendor equipment.

OEM Part Number: QSFP+ to SFP+-40G-DAC-0.5M2FTHT Part Number: QSFP+ to SFP+-40G-DAC-0.5M2FT

Product Highlights

• HT-manufactured DAC assembly in 0.5m (2ft)
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 0.5m (2ft), QSFP+ to SFP+-40G-DAC-0.5M2FT
• 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 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing QSFP+ to SFP+-40G-DAC-0.5M2FT; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

QSFP+ to SFP+-40G-DAC-0.5M2FT is the shortest of 6 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is QSFP+ to SFP+-40G-DAC-1M3FT at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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.

Compatibility is more than matching the QSFP+ to SFP+ shape. This assembly is prepared for hosts expecting QSFP+ to SFP+-40G-DAC-0.5M2FT and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as QSFP+ to SFP+-40G-DAC-0.5M2FT in 0.5m (2ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

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.
