Cisco Q56-200-CU150CM Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 1.5m (5ft)

This 1.5m (5ft) DAC cable is built for Cisco equipment requiring the Q56-200-CU150CM interface. The 200Gbps link uses QSFP56 to QSFP56 and is supplied as one complete tested assembly.

OEM Part Number: Q56-200-CU150CMHT Part Number: Q56-200-CU150CM

Product Highlights

• Compatible alternative to Cisco Q56-200-CU150CM
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 1.5m (5ft), Q56-200-CU150CM
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• Maximum power consumption: 0.03W Per End
• Minimum bend radius: 39mm

The rated power consumption is 0.03W Per End. 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 additional half metre beyond a one-metre assembly gives Q56-200-CU150CM useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

Q56-200-CU150CM occupies the middle of this family between Q56-200-CU1M at 1m (3ft) and Q56-200-CU2M at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. 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 30AWG conductors, PVC jacket, minimum bend radius 39mm. 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 IEEE802.3cd, SFF-8436. Confirm that the host firmware and port configuration support the same operating mode.

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.

The HT cable carries the compatibility configuration associated with Q56-200-CU150CM, while its mechanical assembly remains the fixed 1.5m (5ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Cisco software can request a pre-order check.

This product is ordered as Q56-200-CU150CM in 1.5m (5ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
