Extreme Networks 10GB-4-C50-QSFP Compatible QSFP+ to 4SFP+ Passive Breakout 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 10GB-4-C50-QSFP and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: 10GB-4-C50-QSFPHT Part Number: 10GB-4-C50-QSFP

Product Highlights

• Compatible alternative to Extreme Networks 10GB-4-C50-QSFP
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 0.5m (2ft), 10GB-4-C50-QSFP
• Conductor specification: 30AWG
• Minimum bend radius: 21mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21mm. 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 QSFP+ to 4 SFP+ 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 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 10GB-4-C50-QSFP; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

10GB-4-C50-QSFP is the shortest of 6 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 10202 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, SFF-8431 and QSFP+ MSA. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with 10GB-4-C50-QSFP, while its mechanical assembly remains the fixed 0.5m (2ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Extreme Networks software can request a pre-order check.

Quote HT part number 10GB-4-C50-QSFP with the required quantity. The 0.5m (2ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

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, 10GB-4-C50-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.
