{"product_id":"b000t8f544","title":"SONET\/SDH Demystified","description":"\u003cp\u003eIncreasingly, the use of fiber optic cable as a transport for voice, data, video, and Internet traffic is becoming the norm. Sonet (Synchronous Optical Network) and Sdh (Synchronous Digital Hierarchy) are being used with high-speed data transmission. Although Sonet\/Sdh was originally intended for use in broadband Isdn and support leased line services like Ds-1 and Ds-3. Sonet\/Sdh expansion is being fuelled by many of today's biggest industries such as Boeing, Disney and At\u0026amp;T as these companies move their internal global networks to a Sonet\/Sdh infrastructure. This work provides coverage of Sonet\/Sdh technology written at a level that will be understandable to technicians working in the telecommunications industry. It includes detailed examples of Dwdm (dense wavelength division multiplexing) and Wdm (wavelength division multiplexing).\u003c\/p\u003e","brand":"ANT","offers":[{"title":"Ebook","offer_id":67923488604405,"sku":"YSL50177","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/8774\/8597\/files\/4121aIIIRpL._SY1500.jpg?v=1793672052","url":"https:\/\/www.newbooks.store\/products\/b000t8f544","provider":"NewBooks","version":"1.0","type":"link"}
