Cisco QSFP-4 x 10G-AC5M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Copper Breakout Cable, 5m (16ft)

For short, high-density connections, this ACC cable combines 40G performance with a fixed 5m (16ft) cable run. It corresponds to Cisco QSFP-4 x 10G-AC5M and uses an actively conditioned copper link for the stated high-speed interface.

OEM Part Number: QSFP-4 x 10G-AC5MHT Part Number: QSFP-4 x 10G-AC5M

Product Highlights

• Compatible alternative to Cisco QSFP-4 x 10G-AC5M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to SFP+
• Fixed length and part number: 5m (16ft), QSFP-4 x 10G-AC5M
• Cable construction: Active Twinax
• Conductor specification: 28AWG
• Maximum power consumption: ≤1.8W
• Minimum bend radius: 40mm

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.

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 5m (16ft) length gives QSFP-4 x 10G-AC5M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.

QSFP-4 x 10G-AC5M occupies the middle of this family between QSFP-4 x 10G-AC3M at 3m (10ft) and QSFP-4 x 10G-AC7M 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 28AWG conductors, PVC (OFNR) jacket, minimum bend radius 40mm. 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.

For this Cisco application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Quote HT part number QSFP-4 x 10G-AC5M with the required quantity. The 5m (16ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

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.
