QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT 200G QSFP56 4 x 50G PAM4 to 2 x 100G QSFP56 2 x 50G PAM4 Passive Copper Breakout Cable, 2.5m (8ft)

Use the QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT compatible assembly where a 200G connection is required between compatible ports. This page covers the 2.5m (8ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: QSFP56 to 2x QSFP56-200G-DAC-2.5M8FTHT Part Number: QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT

Product Highlights

• HT-manufactured DAC assembly in 2.5m (8ft)
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to 2x QSFP56
• Fixed length and part number: 2.5m (8ft), QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: 0.1W (200G End) 0.1W (100G Per End)
• Minimum bend radius: 30mm

The rated power consumption is 0.1W (200G End) 0.1W (100G 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 intended application is determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd, SFF-8665, QSFP56 MSA. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP56 to 2x QSFP56 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.

The 2.5m (8ft) version is useful when a two-metre run would leave insufficient working slack. Before installation, check the complete horizontal and vertical path so that QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT reaches both ports without tension at either connector.

QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT occupies the middle of this family between QSFP56 to 2x QSFP56-200G-DAC-2M7FT at 2m (7ft) and QSFP56 to 2x QSFP56-200G-DAC-3M10FT at 3m (10ft). 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 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 30mm. 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.

Our compatibility setup for Generic QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT is checked together with the physical 2.5m (8ft) 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.

This product is ordered as QSFP56 to 2x QSFP56-200G-DAC-2.5M8FT in 2.5m (8ft). 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.

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.
