QSFP 112 to QSFP 112-400G-DAC-0.5M2FT 400G QSFP112 4 x 100G PAM4 Passive Copper Twinax Cable, 0.5m (2ft)

Use the QSFP 112 to QSFP 112-400G-DAC-0.5M2FT compatible assembly where a 400G connection is required between compatible ports. This page covers the 0.5m (2ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: QSFP 112 to QSFP 112-400G-DAC-0.5M2FTHT Part Number: QSFP 112 to QSFP 112-400G-DAC-0.5M2FT

Product Highlights

• HT-manufactured DAC assembly in 0.5m (2ft)
• 400G connectivity at 400Gbps
• Interface configuration: QSFP 112 to QSFP 112
• Fixed length and part number: 0.5m (2ft), QSFP 112 to QSFP 112-400G-DAC-0.5M2FT
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• 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.

The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing QSFP 112 to QSFP 112-400G-DAC-0.5M2FT; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

QSFP 112 to QSFP 112-400G-DAC-0.5M2FT is the shortest of 3 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is QSFP 112 to QSFP 112-400G-DAC-1M3FT at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

This assembly uses 30AWG 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.

For this Generic application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

This product is ordered as QSFP 112 to QSFP 112-400G-DAC-0.5M2FT in 0.5m (2ft). 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.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

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.
