The Government of India and the Government of Delhi jointly set up the Delhi Metro Rail Corporation (DMRC) in 1995.Construction started in 1998, and The first section, on the Red Line, opened in 2002, Followed by the Yellow Line in 2004, The Blue Line in 2005, its branch line in 2009, The Green and Violet Lines in 2010 and The Delhi Airport Metro Express in 2011. A company under the name DMRC was registered on 30.05.1995 under the companies act for construction and operation of the metro project.The Government of India and the Government of Delhi jointly set up a company called the Delhi Metro Rail Corporation (DMRC) on March 5, 1995 with E. Sreedharan as the managing director. It started functioning in November, 1997. It appointed General consultant in August, 1998 to assist them for implementation of the project. It is having 142 stations in the Rail corridor and 35 stations in the Metro corridor (underground). It has a combination of elevated, at-grade and underground lines and uses both broad gauge and standard gauge rolling stock. The Delhi Metro Rail Corporation has been certified by the United Nations as the first metro rail and rail-based system in the world to get “carbon credits for reducing greenhouse gas emissions” Delhi Metro brought a revolutionary change in the city transport. It has also reduced the travel time. Also the pollution level is reduced to about 50%. A large number of commuters are having a lot of convenience in reaching their desired destination in the required time. Dr. E.

FOTS is further differently prescribed in following ways. The section overhead (SOH) of a STM-1 signal is divided into two parts: the regenerator section overhead (RSOH) and the multiplex section overhead (MSOH). Fiber optics eases up the data and voice communication or access to various systems at different stations. SDH MUX NETWORKS Synchronous Digital Hierarchy(SDH) Synchronous Digital Hierarchy (SDH) are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers or highly coherent light from lightemitting diodes (LEDs).52 Mbit/s OC-3 fiber-optic circuit.Barakhamba Road. This network is based on fiber optical cables on both sides of the track. Thus optical fiber communication is the method of transmitting information through optical fibers. The STM-1 frame is transmitted in exactly 125 µs. At low transmission rates data can also be transferred via an electrical interface. In case of fiber optic failure.Delhi Metro Rail Corporation Ltd Metro Bhawan Fire Brigade Lane. 9 Training Report-“ Delhi Metro Rail Corporation" . FOTS can be termed as the backbone of DMRC telecommunication network. level 1) frame is the basic transmission format for SDH—the first level of the synchronous digital hierarchy. New Delhi-110001 Fiber Optics Transmission system(FOTS) It is the transmission system that uses optical fiber as communication media. The fiber is redundant for security and protection. communication can take place via spare fiber while the fiber that is down may be fixed.

TDM involves sequencing groups of a few bits or bytes from each individual input stream. The multiplexing divides the capacity of the high-level communication channel into several low-level logical channels.Barakhamba Road. If done sufficiently quickly. A device that performs the multiplexing is called a multiplexer (MUX). The multiplexed signal is transmitted over a communication channel. New Delhi-110001 MULTIPLEXER(MUX) In telecommunications and computer networks. A pair of 9600 bit/s modems and one dedicated analog communications circuit from the airport ticket desk back to the airline data center are also installed . In DMRC. The Time-division multiplexing (TDM) is a digital technology. the Time Division Multiplexing is used. and in such a way that they can be associated with the appropriate receive. the receiving devices will not detect that some of the circuit time was used to serve another logical communication path. multiplexing (also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium. the airline has installed a pair of multiplexers.Delhi Metro Rail Corporation Ltd Metro Bhawan Fire Brigade Lane. 13 Training Report-“ Delhi Metro Rail Corporation" .
