QSFP 112 to QSFP 112-400G-DAC-1M3FT 400G QSFP112 4 x 100G PAM4 Passive Copper Twinax Cable, 1m (3ft)

The HT-manufactured QSFP 112 to QSFP 112-400G-DAC-1M3FT compatible cable provides 400G connectivity for multi-vendor 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 112 to QSFP 112-400G-DAC-1M3FTHT Part Number: QSFP 112 to QSFP 112-400G-DAC-1M3FT

Product Highlights

• HT-manufactured DAC assembly in 1m (3ft)
• 400G connectivity at 400Gbps
• Interface configuration: QSFP 112 to QSFP 112
• Fixed length and part number: 1m (3ft), QSFP 112 to QSFP 112-400G-DAC-1M3FT
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: 0.1W Per End
• Minimum bend radius: 46mm

The rated power consumption is 0.1W 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 400G Ethernet.

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 112 to QSFP 112-400G-DAC-1M3FT 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.

QSFP 112 to QSFP 112-400G-DAC-1M3FT occupies the middle of this family between QSFP 112 to QSFP 112-400G-DAC-0.5M2FT at 0.5m (2ft) and QSFP 112 to QSFP 112-400G-DAC-1.5M5FT at 1.5m (5ft). 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, PET jacket, minimum bend radius 46mm. 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 QSFP 112 to QSFP 112-400G-DAC-1M3FT 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.

Use part number QSFP 112 to QSFP 112-400G-DAC-1M3FT for the 1m (3ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
