Cisco QSFP-4SFP10G-CU1M Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 1m (3ft)

The HT-manufactured QSFP-4SFP10G-CU1M compatible cable provides 40G connectivity for Cisco equipment. This 1m (3ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

OEM Part Number: QSFP-4SFP10G-CU1MHT Part Number: QSFP-4SFP10G-CU1M

Product Highlights

• Compatible alternative to Cisco QSFP-4SFP10G-CU1M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 1m (3ft), QSFP-4SFP10G-CU1M
• 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.

QSFP-4SFP10G-CU1M occupies the middle of this family between QSFP-4SFP10G-CU50CM at 0.5m (2ft) and QSFP-4SFP10G-CU2M at 2m (7ft). It adds 0.5m 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.

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.

At 1m (3ft), QSFP-4SFP10G-CU1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

Our compatibility setup for Cisco QSFP-4SFP10G-CU1M is checked together with the physical 1m (3ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Quote HT part number QSFP-4SFP10G-CU1M with the required quantity. The 1m (3ft) 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-CU1M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1m (3ft) 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.
