Designed for CN4200-based optical transport networks, this line card carries 10 Gigabit Ethernet services and STM-64 payloads within the same card, enabling high-capacity Ethernet connectivity alongside traditional SDH\/SONET transport in carrier deployments. As a CN4200 line card, it is intended to extend existing CN4200 installations by adding 10 GbE endpoints and STM-64 trunking without requiring a separate interface module. The part number B-720-1086-400 is referenced in vendor catalogs as a CN4200 10GBE \u0026amp; STM-64 line card, underscoring its role in aggregating Ethernet traffic over STM-64 paths. In typical deployments, it supports backhaul links between urban aggregation points, interconnections between data centers, and service delivery scenarios where Ethernet traffic must be carried over STM-64 transport within the CN4200 platform. Installation and operation depend on using it within compatible CN4200 slots and adhering to the CN4200 subsystem’s guidelines for line-card insertion, slot power, and software\/firmware requirements. This card represents a modular option for scaling CN4200 networks to accommodate higher Ethernet service density without replacing existing chassis, aligning with environments prioritizing Ethernet over SDH\/SONET transport in a compact, integrated form factor.\u003c\/p\u003e\u003c\/div\u003e","brand":"Ciena","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678047568174,"sku":null,"price":1088.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_daf370e8-a33a-482a-a3f3-5c3c074d8c12.jpg?v=1769571080","url":"https:\/\/plgautomation.com\/products\/ciena-b-720-1086-400-line-card","provider":"PLG Automation ","version":"1.0","type":"link"}
