Cisco SFP-H25G-CU1.5M Compatible 25G SFP28 Passive Copper Twinax Cable, 1.5m (5ft)

For short, high-density connections, this DAC cable combines 25G performance with a fixed 1.5m (5ft) cable run. It corresponds to Cisco SFP-H25G-CU1.5M and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: SFP-H25G-CU1.5MHT Part Number: SFP-H25G-CU1.5M

Product Highlights

• Compatible alternative to Cisco SFP-H25G-CU1.5M
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 1.5m (5ft), SFP-H25G-CU1.5M
• 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.

The additional half metre beyond a one-metre assembly gives SFP-H25G-CU1.5M useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

SFP-H25G-CU1.5M occupies the middle of this family between SFP-H25G-CU1M at 1m (3ft) and SFP-H25G-CU2M at 2m (7ft). 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.

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.

Each SFP-H25G-CU1.5M 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 Cisco platform should be included with the order.

This product is ordered as SFP-H25G-CU1.5M in 1.5m (5ft). 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.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

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.
