Arista Networks CAB-SFP-SFP-4M Compatible 10G SFP+ Passive Copper Twinax Cable, 4m (13ft)

The HT-manufactured CAB-SFP-SFP-4M compatible cable provides 10G connectivity for Arista Networks equipment. This 4m (13ft) 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: CAB-SFP-SFP-4MHT Part Number: CAB-SFP-SFP-4M

Product Highlights

• Compatible alternative to Arista Networks CAB-SFP-SFP-4M
• 10G connectivity at 10Gbps
• Interface configuration: SFP+ to SFP+
• Fixed length and part number: 4m (13ft), CAB-SFP-SFP-4M
• Cable construction: Passive Twinax
• Conductor specification: 24AWG
• 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 4m (13ft) length gives CAB-SFP-SFP-4M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

CAB-SFP-SFP-4M occupies the middle of this family between CAB-SFP-SFP-3M at 3m (10ft) and CAB-SFP-SFP-5M at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. 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 24AWG 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.

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.

For this Arista Networks 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 CAB-SFP-SFP-4M in 4m (13ft). 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.

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.
