Cisco Forward Error Correction Soft Decision on WDM Trunk Port | License — L-NCS2K-SD-FEC=

Strengthen WDM trunk reliability with Cisco Forward Error Correction Soft Decision licensing for one trunk port. This electronic software license enables soft-decision FEC on supported optical transport infrastructure, helping improve tolerance to signal degradation across demanding long-haul and metro links. Built for environments where transport stability directly affects service continuity, this license is suited to teams managing dense wavelength-division multiplexing systems that need tighter control over optical performance without changing the underlying hardware path. It is a targeted entitlement, not a broad software bundle, which makes it a precise fit for network architects standardizing feature activation by port. Because the license is delivered electronically, it supports faster fulfillment and cleaner asset management for procurement and operations teams. For organizations protecting critical backbone traffic, this is the kind of license that justifies itself through fewer transport issues, better margin management, and more predictable optical behavior on the trunk. Ideal For Activating soft-decision FEC on a Cisco WDM trunk port in a metro transport network Adding optical margin protection to long-haul wavelength-division multiplexing links Standardizing port-level feature licensing across carrier transport infrastructure Supporting procurement of a single entitlement for a specific trunk port Why This Product 1 Port-specific licensing instead of broad feature bundles 2 Electronic delivery for faster fulfillment 3 Designed for WDM trunk transport environments 4 Single-port entitlement for precise capacity alignment
