Nordost Norse 2 Series Heimdall 2 Ethernet Cable

Reference Network Transmission for High-End Streaming | Available at Trimira Audio

The Nordost Heimdall 2 Ethernet Cable is a high-performance network cable within Nordost's Norse 2 Series, designed for demanding high-resolution streaming and network-audio installations.

Combining 23 AWG silver-plated solid-core OFC conductors, S/FTP shielding, FEP insulation, controlled high-frequency geometry, and shielded RJ45 termination, Heimdall 2 provides a robust physical Ethernet connection between network switches, routers, NAS devices, music servers, and network streamers.

At Trimira Audio, we recommend the Heimdall 2 Ethernet Cable for reference-oriented digital systems where high-quality shielding, conductor construction, and reliable high-bandwidth network transmission are priorities.

Key Features & Technological Innovations

Cat 8 High-Bandwidth Architecture

Heimdall 2 is specified for Category 8 high-frequency network transmission, providing bandwidth well beyond the requirements of conventional gigabit Ethernet audio systems.

For network audio, this provides substantial physical-layer bandwidth and transmission headroom.

Solid-Core Silver-Plated OFC Conductors

The cable uses 8 × 23 AWG solid-core conductors manufactured from 99.99999% high-purity OFC copper with pure silver plating.

The solid-core architecture provides consistent conductor geometry across the four twisted pairs.

Screened & Fully Shielded Twisted Pair — S/FTP

Each twisted pair is individually foil-shielded, with an additional outer braided shield surrounding the complete cable assembly.

This dual-layer construction is designed to reduce:

• RF interference
• Electromagnetic interference
• Inter-pair crosstalk
• External high-frequency electrical noise

High-Grade FEP Insulation

The conductors use Fluorinated Ethylene Propylene (FEP) insulation, providing a mechanically stable dielectric environment with controlled electrical characteristics.

Precision Shielded RJ45 Connectors

Heimdall 2 uses fully shielded metal-jacketed RJ45 connectors designed to maintain shielding continuity, secure grounding, and reliable mechanical contact.

Technical Specifications

Network Audio Applications

Heimdall 2 is suitable for Ethernet connections between:

• Network routers
• Ethernet switches
• NAS storage
• Music servers
• Network streamers
• Network bridges
• Digital audio systems

For a correctly functioning Ethernet network, digital audio data is transmitted using error detection and correction protocols. The principal engineering considerations for the physical cable are therefore bandwidth, impedance, shielding, connector quality, and reliable data transmission.
