Arista Networks CAB-SFP-SFP-2.5M Compatible 10G SFP+ Passive Copper Twinax Cable, 2.5m (8ft)

The CAB-SFP-SFP-2.5M cable offers a direct SFP+ to SFP+ connection at 10Gbps. Its 2.5m (8ft) length and DAC construction are intended for Arista Networks equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: CAB-SFP-SFP-2.5MHT Part Number: CAB-SFP-SFP-2.5M

Product Highlights

• Compatible alternative to Arista Networks CAB-SFP-SFP-2.5M
• 10G connectivity at 10Gbps
• Interface configuration: SFP+ to SFP+
• Fixed length and part number: 2.5m (8ft), CAB-SFP-SFP-2.5M
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• Maximum power consumption: ≤0.1W
• Minimum bend radius: 23mm

The rated power consumption is ≤0.1W. 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 10G Ethernet. Listed interface and protocol references include 1x InfiniBand QDR, DDR, SDR, 10 Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

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 CAB-SFP-SFP-2.5M reaches both ports without tension at either connector.

CAB-SFP-SFP-2.5M occupies the middle of this family between CAB-SFP-SFP-2M at 2m (7ft) and CAB-SFP-SFP-3M 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 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 23mm. 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.

Each CAB-SFP-SFP-2.5M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Arista Networks platform should be included with the order.

When ordering, specify CAB-SFP-SFP-2.5M, cable length 2.5m (8ft) 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, CAB-SFP-SFP-2.5M and the 2.5m (8ft) length for easier inventory control.

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.
