{"product_id":"optical-communication-theory-and-techniques-von-enrico-forestieri-hrsg","title":"Optical Communication Theory and Techniques","description":"Since the advent of optical communications, a greattechnological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Sta- ing from a few Mb\/s single channel systems, a fast and constant technological development has led to the actual 10 Gb\/s per channel dense wavelength - vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb\/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers. Nevertheless, despite such a pace in technological progress, optical c- munications are still in a primitive stage if compared, for instance, to radio communications: the widely spread on-off keying (OOK) modulation format is equivalent to the rough amplitude modulation (AM) format, whereas the DWDM technique is nothing more than the optical version of the frequency - vision multiplexing (FDM) technique. Moreover, adaptive equalization, ch- nel coding or maximum likelihood detection are still considered something “exotic” in the optical world. This is mainly due to the favourable char- teristics of the fiber optic channel (large bandwidth, low attenuation, channel stability, ...), which so far allowed us to use very simple transmission and detection techniques.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780387231327\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781441935779\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9780387231327","offer_id":50828653254,"sku":"9780387231327","price":160.49,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9781441935779","offer_id":39414814605405,"sku":"9781441935779","price":160.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/18b2274a-9d12-47df-9b71-1b801281c618.jpg?v=1778213196","url":"https:\/\/shop.autorenwelt.de\/en\/products\/optical-communication-theory-and-techniques-von-enrico-forestieri-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
