It supports OC-768\/STM-256\/OTU3 mapping on the OTN path, enabling SONET\/SDH and OTN services within the 6500 architecture. Designed for use in 6500 D\/S-Series shelves, the NTK529SDE5 sits in the modular circuit-pack ecosystem that allows operators to mix 40G OCI capacity with other service cards to tailor high-capacity transport. This variant denotes 40G OCI functionality with 40\/43G OCI mapping, making it suitable for deployments requiring a 40 Gbps client interface and OC-768\/STM-256\/OTU3 compatibility in backbone or metro networks while leveraging the 6500 platform’s OTN switching capabilities. In practice, it enables circuit-switched transport options alongside packet\/OTN services in a scalable, multi-service transport environment.\u003c\/p\u003e\u003c\/div\u003e","brand":"Ciena","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678045667630,"sku":null,"price":783.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e33cc0a5-5f96-4ce7-b203-074125dcb3f2.jpg?v=1769571051","url":"https:\/\/plgautomation.com\/products\/ciena-ntk529sde5-40g-network-interface-card-module","provider":"PLG Automation ","version":"1.0","type":"link"}
