Specifications

Power and Thermal Planning

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.

Length Selection and Installation Planning

With 7m (23ft) available, the installer has more routing freedom but also more cable to control. Determine where any remaining service loop will be stored, preserve the stated bend radius and keep the loop away from sharp edges and hot exhaust. The complete copper assembly and both connector housings should remain accessible for inspection and removal. Within this family, QSFP-4 x 10G-AC5M is shorter at 5m (16ft), while QSFP-4 x 10G-AC9M is the next longer choice at 9m (29ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

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.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 44.5mm; the stated power consumption is ≤1.8W; the jacket material is PVC (OFNR).

Cable Construction and Routing

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.

Network and Protocol Considerations

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.

Breakout Port Mapping

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.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Neutral packaging and customer-specific packing documentation are available on request.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. Keep QSFP-4 x 10G-AC7M associated with 7m (23ft) throughout the order and receiving record.

Cisco Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
