Product overview

The AddOn SFP-H25G-CU2M-AO is a Cisco-compatible 25GBase-CU SFP28 direct attach cable engineered for high-speed datacenter connectivity. This passive twinax copper cable delivers 25 Gbps performance over a maximum distance of 2 meters, supporting 25G Ethernet and backward-compatible with 10G Ethernet and 32G Fiber Channel applications. Featuring SFP28 connectors on both ends, the cable operates with minimal power consumption (1W per end) and maintains reliability with an MTBF of 1,000,000 hours. TAA and MSA compliant, it meets enterprise procurement standards and includes DDM/DOM support for enhanced network monitoring. The 30 AWG twinax construction ensures signal integrity across short-reach interconnects, making it ideal for top-of-rack switches, server connections, and storage area networks requiring cost-effective, low-latency performance.

Best for

Datacenter Switching
Connect 25G-capable switches in top-of-rack configurations with passive copper DACs, eliminating active transceiver costs while maintaining full 25 Gbps throughput over 2-meter distances.
Server-to-Switch Interconnects
Link servers equipped with SFP28 NICs directly to datacenter switches using this passive cable, supporting 25G Ethernet and backward-compatible 10G Ethernet for flexible network upgrades.
Storage Area Networks (SAN)
Deploy in SAN environments requiring 32G Fiber Channel support; the cable's 2-meter reach accommodates typical rack-level storage-to-switch connections with minimal latency.
High-Performance Computing (HPC)
Utilize in HPC clusters where low-latency, high-bandwidth interconnects between compute nodes and fabric switches are critical, leveraging the cable's 25 Gbps capacity and 1,000,000-hour MTBF.
Network Upgrades & Migrations
Replace older 10G infrastructure with 25G capability using this TAA-compliant, MSA-standard cable, ensuring compatibility with existing Cisco equipment and enterprise procurement requirements.

Frequently asked questions

What is the maximum distance this cable can reliably operate?

The SFP-H25G-CU2M-AO supports a maximum reach of 2 meters (6.6 feet) using passive twinax copper. This distance is optimized for top-of-rack and intra-rack datacenter connectivity. Beyond 2 meters, signal degradation may occur; active DACs or optical solutions are recommended for longer distances.

Is this cable compatible with non-Cisco equipment?

Yes. While designed as a Cisco SFP-H25G-CU2M compatible cable, it meets MSA (Multi-Source Agreement) standards and SFF-8402/SFF-8431 specifications, ensuring compatibility with any SFP28-equipped networking equipment from multiple vendors. MSA compliance guarantees interoperability across Cisco, Arista, Juniper, and other datacenter platforms.

What are the power consumption requirements?

This passive DAC consumes only 1W per end, totaling 2W maximum for the cable pair. This minimal power draw is a key advantage over active DACs, which typically consume 3-5W per end. The low power consumption reduces datacenter power budgets and cooling requirements.

Does this cable support monitoring and diagnostics?

Yes, the cable supports DDM/DOM (Digital Diagnostics Monitoring / Digital Optical Monitoring), enabling real-time monitoring of cable health, temperature, and performance metrics. This capability allows proactive detection of signal degradation and supports automated network management and troubleshooting in production environments.

What compliance certifications does this cable hold?

The SFP-H25G-CU2M-AO is TAA (Trade Agreements Act) compliant, MSA compliant, and certified for CE and RoHS standards. TAA compliance makes it eligible for U.S. government and regulated sector procurement. MSA certification ensures vendor-neutral interoperability, and RoHS compliance meets environmental regulations.

Can this cable be used for Fiber Channel applications?

Yes, the cable supports 32G Fiber Channel (28.05 Gbps) in addition to 25G Ethernet and backward-compatible 10G Ethernet. This multi-protocol capability makes it suitable for SAN (Storage Area Network) environments where Fiber Channel connectivity is required alongside Ethernet infrastructure.

What is the expected lifespan of this cable?

The cable has an MTBF (Mean Time Between Failures) rating of 1,000,000 hours, indicating long-term reliability in continuous-duty datacenter environments. This translates to approximately 114 years of continuous operation, supporting extended SLA commitments and reducing unplanned replacement costs.
