Anda Networks 645-410 OC3 STM1-1T Interface Module

The Anda Networks 645-410 OC3/STM-1-1T Interface Module is a single-port OC-3/STM-1 trunk card designed for Anda Etheredge 4000-series systems, delivering a dedicated optical interface for high-capacity transport. Marketed as a 1T module, it is intended to interconnect network elements within SDH/SONET-based backhaul and metro networks, enabling carriers or large enterprises to extend their transport fabric over fiber. In typical deployments, the module serves as the uplink or interconnect connection within a modular Anda chassis, pairing with other interface cards to create a complete SDH/SONET transport path. The 645-410 designation appears in supplier listings as the Anda OC-3/STM-1 trunk module compatible with Etheredge 4000 hardware, underscoring its role as a dedicated OC-3/STM-1 interface option within that platform. As with other trunk cards in SDH/SONET environments, it is intended to reside in a compatible Anda chassis and operate as part of a broader transport network, enabling efficient handoff of SDH/SONET traffic across OC-3/STM-1 links and supporting modular, scalable fiber-based transport topology.
