What is SDH? Possible answers: SDH is an International Standard for high-speed synchronous optical telecommunication networks---a Synchronous Digital Hierarchy 3. Tell us the main applicat lication of sdh? Possible answers: The SDH signal is capable of transporting all the common ributary signals found in today s telecommunication networks s mins II. Pre-reading activities 1. Ask the Ss the following two questions related to the theme of the text 1)Can you enumerate what you contacted in the study of the courses including optical communications? Possible answers: optical fiber, OA, FTTB, FTTO, FTTN, FTTH, etc 2) What is the application of optical fiber? Do you know anything about WDM? Possible answers: optical fiber is a transmission medium through which numerous signals are transmitted, it can be used to build optical networks Wavelength Division Multiplexing(WDM) enables the utilization of a significant portion of the available fiber bandwidth by allowing many independent signals to be transmitted simultaneously on one fiber, with each signal located at a different wavelength. (The Ss might be encouraged to discuss this topic before class either in English or in Chinese. 2. Teacher leads into the text by saying: From the explanation you gave about optical fiber and WDM, and also youve studied TDM before, based on your knowledge about them, I,'m sure you can achieve a good understanding of the new text, WDM because it is mainly on the operation and advances of WDM.
