EXTREME NETWORKS 25G-DACP-SFPZ5M - Direct Attach Copper Cable

Overview

The EXTREME NETWORKS 25G-DACP-SFPZ5M is an enterprise-grade, passive direct attach copper (DAC) twinaxial cable assembly custom-engineered for ultra-short range, high-density server-to-switch and switch-to-switch interconnect topologies. This high-velocity 25 Gigabit interconnect resolves structural power budgets and thermal dissipation issues within high-density computing racks by providing an electrical signaling pathway that draws zero operating power from the host system. It establishes immediate, line-rate link optimization without the hardware costs or architectural complexities associated with optical fiber transceivers.

The cable architecture features a premium twinaxial shielded copper core factory-terminated with hot-pluggable Small Form-factor Pluggable 28 (SFP28) housings on both endpoints. Operating over a single multi-gigabit serial data channel, the interconnect sustains an aggregate line rate of 25.78 Gbps. The 0.5-meter (1.6 ft) length is tightly optimized for adjacent or internal rack routing, leveraging an ultra-low latency physical signature that relies on the host network equipment's integrated electronic dispersion compensation (EDC) to preserve bit error rate (BER) metrics.

Tailored for deployment in mission-critical corporate data centers, high-frequency financial clusters, and service provider core environments, this cable hooks up top-of-rack (ToR) distribution switches directly to neighboring network attached storage (NAS) devices or physical server nodes. It maintains full native compatibility with Extreme Networks enterprise hardware platforms, including the X695, 5420, 5520, and 5720 universal switching series. Avoid utilizing this 0.5-meter passive cable for structural vertical inter-rack hops exceeding its physical radius, or within uncompressed network ports where active signal amplification or forward error correction (FEC) profiles are explicitly disabled.

Key Features

• Passive twinaxial architecture draws zero operational wattage from host ports.

• Standardized SFP28 interfaces yield a continuous 25.78 Gbps line throughput.

• Ultra-short 0.5-meter span eliminates intra-rack cable congestion points.

• Hot-swappable pluggable shells facilitate effortless toolless deployment.

• Full MSA SFF-8402 conformance guarantees wide peripheral interoperability.
