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.\u003c\/p\u003e\u003c\/div\u003e","brand":"Anda","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659998724398,"sku":null,"price":3618.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fafd3057-df8f-4609-8fdf-07744eb02067.jpg?v=1769531553","url":"https:\/\/plgautomation.com\/products\/anda-networks-645-410-oc3-stm1-1t-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
