Cisco QSFP-4SFP10G-CU2M Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 2m (7ft)

With a fixed 2m (7ft) cable and QSFP+ to 4 SFP+, the QSFP-4SFP10G-CU2M compatible assembly simplifies 40G deployment. It is manufactured and tested by HT for Cisco equipment.

OEM Part Number: QSFP-4SFP10G-CU2MHT Part Number: QSFP-4SFP10G-CU2M

Product Highlights

• Compatible alternative to Cisco QSFP-4SFP10G-CU2M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 2m (7ft), QSFP-4SFP10G-CU2M
• Conductor specification: 30AWG
• Minimum bend radius: 21mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21mm. 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, SFF-8431 and QSFP+ MSA. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP+ to 4 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.

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.

QSFP-4SFP10G-CU2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

QSFP-4SFP10G-CU2M occupies the middle of this family between QSFP-4SFP10G-CU1M at 1m (3ft) and QSFP-4SFP10G-CU3M at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. 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 4 SFP+ shape. This assembly is prepared for hosts expecting QSFP-4SFP10G-CU2M 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.

Quote HT part number QSFP-4SFP10G-CU2M with the required quantity. The 2m (7ft) 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.

Every QSFP-4SFP10G-CU2M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 2m (7ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.
