Cisco ASR 900 A900-IMA4C3794 4-Port C37.94 Module

Add specialized transport connectivity to Cisco ASR 900 platforms with a 4-port C37.94 interface module. Built for carrier and service-provider environments, this module is designed for deployments where interface specificity, platform fit, and network continuity matter more than commodity expansion. C37.94 is used in optical transport and telecom applications that require disciplined signal handling and predictable integration with existing routing infrastructure. By adding four ports in a compact interface module, this component helps teams expand service capability without changing the underlying ASR 900 architecture. For infrastructure buyers, the value is in targeted expansion. Instead of overprovisioning with a broader, more expensive platform change, this module adds the exact connectivity needed for specialized transport use cases. That keeps the ASR 900 aligned to long-term network design while preserving investment in the base system and operational model.
