SONET Synchronous Optical Network
SONET Synchronous Optical Network Multiplex electrical signals (Digital) from different sources and creates optical carrier (OC). USA, CANADA and JAPAN developed T1 Standard. ANSI develop SONET. The rest of the world uses a primary rate of E1. ITU-T develop SDH. Topics What is SONET? What is Synchronous Digital Hierarchy? What is SDH? What… -
DWDM Dense Wavelength Division Multiplexing
Prerequisite Multiplexing Optical Fiber PCM PDH SDH Transmission Fundamental WDM Wavelength division Multiplexing (WDM) technique increase the capacity of signal carrying medium. WDM technique assign different frequency / wavelength value to every incoming signal. These signals are multiplexed on a single sharing medium. SONET/SDH use TDM technique and transmit data in the form of a… -
