The practical  components of WDM system models have been simulated through software to  understand the behavior of these components and overall system considerations  because  of the role played by these components in the transmission processes (e.g.,  optical fiber, continuous wave laser diode (CW) and multiplexer (MUX)). Two types  of amplifiers (Raman Amplifiers and Erbium Doped Fiber Amplifiers) are  studied that are used to amplify the optical signals. Ultra wideband WDM  system is proposed in this book. The total 3-dB  spectral range obtained is equal to 83-nm as compared with 75-nm  that is obtained today. An improved gain-flatness (7 dB as compared with the  same value that is obtained today but with short distance) of a Raman amplifier  with wide gain-bandwidth and a high gain-output power is obtained by using  multipump configuration. 96 channels are simulated with channel spacing equal  to 100 GHz (0.8 nm); distance more than 700 km and with more than distance between amplifiers 71.75 km (as  compared with 50 km that is used today).\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843379489\"\u003e\u003ch3\u003eUltra wideband WDM\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843379489","offer_id":39470080753757,"sku":"9783843379489","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6a946238-3e2f-471a-9893-fc8aff8ce730.jpg?v=1770528949","url":"https:\/\/shop.autorenwelt.de\/products\/optical-fiber-wdm-dwdm-transmission-von-laith-kadhim","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
