020QCD Huawei OptiX OSN System Module

The Huawei 020QCD is a cross-connect and scheduling assembly board, identified by the functional code SSN2PSXCSA. This card provides central switching and signal routing capabilities within Huawei’s optical transport network equipment, enabling the management and distribution of traffic across multiple service channels.

This module is designed for deployment in Huawei OptiX OSN series multi-service transport platforms, commonly used in telecommunications carrier networks and large enterprise backbone infrastructure. The PSXCSA board handles cross-connect functions essential for SDH/SONET and packet-based service switching within the chassis.

The SSN2PSXCSA represents equipment from Huawei’s established OptiX transmission portfolio. While these platforms remain operational in many networks, organisations should verify compatibility with their specific OSN chassis configuration and current network requirements.
