SFP-H25G-CU3M= is a Cisco 3-meter 25G SFP28 Passive Direct Attach Copper Twinax Cable (DAC). It is a high-speed, cost-effective solution for short-reach 25GBASE-CR1 connections within data center racks and between adjacent cabinets. Engineered for high-density environments, it delivers 25Gbps full-duplex transmission with zero power consumption, ultra-low latency, and superior signal integrity.
25Gbps High-Speed TransmissionFull-duplex 25.78125 Gbps, compliant with IEEE 802.3by 25GBASE-CR1 and SFP28 MSA standards.
Passive Copper DesignPassive twinax cable with 0W power consumption, maximizing energy efficiency. Lowest-cost, lowest-latency option for short-reach links.
Hot-Swappable SFP28Online Insertion and Removal (OIR) without network downtime, simplifying installation and maintenance.
High-Density & FlexibleLightweight 30AWG cable with a small bend radius (~30mm), ideal for high-density rack deployments.
Cisco Compatibility & QualityFully tested and certified for Cisco switches (Nexus 9000/3000, Catalyst 9300/9500 series).
