Cisco SFP-H25G-CU3M Compatible 25G SFP28 Passive Copper Twinax Cable, 3m (10ft)

Designed for hosts that recognize SFP-H25G-CU3M, this SFP28 to SFP28 cable delivers 25G transmission over a fixed 3m (10ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: SFP-H25G-CU3MHT Part Number: SFP-H25G-CU3M

Product Highlights

• Compatible alternative to Cisco SFP-H25G-CU3M
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 3m (10ft), SFP-H25G-CU3M
• Conductor specification: 30AWG
• Minimum bend radius: 21.25mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21.25mm. 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.

SFP-H25G-CU3M occupies the middle of this family between SFP-H25G-CU2.5M at 2.5m (8ft) and SFP-H25G-CU4M at 4m (13ft). It adds 0.5m 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.

The intended application is 25G Ethernet, Data Center, 5G Wireless. Listed interface and protocol references include IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000. 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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

Compatibility is more than matching the SFP28 to SFP28 shape. This assembly is prepared for hosts expecting SFP-H25G-CU3M and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as SFP-H25G-CU3M in 3m (10ft). 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.

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, SFP-H25G-CU3M and the 3m (10ft) 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.
