Cisco QSFP-4 x 10G-AC7M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Copper Breakout Cable, 7m (23ft)

Use the QSFP-4 x 10G-AC7M compatible assembly where a 40G connection is required between compatible ports. This page covers the 7m (23ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: QSFP-4 x 10G-AC7MHT Part Number: QSFP-4 x 10G-AC7M

Product Highlights

• Compatible alternative to Cisco QSFP-4 x 10G-AC7M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 7m (23ft), QSFP-4 x 10G-AC7M
• Cable construction: Active Twinax
• Conductor specification: 26AWG
• Maximum power consumption: ≤1.8W
• Minimum bend radius: 44.5mm

The rated power consumption is ≤1.8W. 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.

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 44.5mm. 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-8431, SFF-8432, SFF-8472 SFP+ MSA, SFF-8436 QSFP+ MSA. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP+ to SFP+ configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

The extended 7m (23ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated ACC construction avoids a chain of separate modules and patch leads.

QSFP-4 x 10G-AC7M occupies the middle of this family between QSFP-4 x 10G-AC5M at 5m (16ft) and QSFP-4 x 10G-AC9M at 9m (29ft). 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.

The assembly is configured for equipment that recognizes QSFP-4 x 10G-AC7M. 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.

When ordering, specify QSFP-4 x 10G-AC7M, cable length 7m (23ft) 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.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
