Cisco QSFP-H40G-CU1.5M Compatible 40G QSFP+ Passive Copper Cable, 1.5m (5ft)

This HT cable matches the QSFP-H40G-CU1.5M requirement for Cisco equipment. The 1.5m (5ft) assembly supports 40G operation and provides a factory-terminated passive copper link without separate optical modules or patch cords; its complete electrical and mechanical details are listed below.

OEM Part Number: QSFP-H40G-CU1.5MHT Part Number: QSFP-H40G-CU1.5M

Product Highlights

• Compatible alternative to Cisco QSFP-H40G-CU1.5M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 1.5m (5ft), QSFP-H40G-CU1.5M
• Conductor specification: 30AWG
• Minimum bend radius: 35mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 35mm. 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-8436, QSFP+ MSA and IEEE 802.3ba. 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 additional half metre beyond a one-metre assembly gives QSFP-H40G-CU1.5M useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

QSFP-H40G-CU1.5M occupies the middle of this family between QSFP-H40G-CU1M at 1m (3ft) and QSFP-H40G-CU2M at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Compatibility is more than matching the QSFP+ to QSFP+ shape. This assembly is prepared for hosts expecting QSFP-H40G-CU1.5M 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.

When ordering, specify QSFP-H40G-CU1.5M, cable length 1.5m (5ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
