Extreme Networks 40GB-C0.5-QSFP Compatible 40G QSFP+ Passive Copper Cable, 0.5m (2ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 0.5m (2ft) cable run. It corresponds to Extreme Networks 40GB-C0.5-QSFP and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: 40GB-C0.5-QSFPHT Part Number: 40GB-C0.5-QSFP

Product Highlights

• Compatible alternative to Extreme Networks 40GB-C0.5-QSFP
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 0.5m (2ft), 40GB-C0.5-QSFP
• Conductor specification: 30AWG
• Minimum bend radius: 35mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 35mm. 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.

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 40GB-C0.5-QSFP; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

40GB-C0.5-QSFP is the shortest of 7 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 10312 at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, QSFP+ MSA and IEEE 802.3ba. Confirm that the host firmware and port configuration support the same operating mode.

The assembly is configured for equipment that recognizes 40GB-C0.5-QSFP. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

When ordering, specify 40GB-C0.5-QSFP, cable length 0.5m (2ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, 40GB-C0.5-QSFP and the 0.5m (2ft) length for easier inventory control.

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.
