A POWERPOINT PRESENTATION …     ON DENSE  WAVELENGTH  DIVISION MULTIPLEXING --PRESENTED  BY NITESH  SRIVASTAVA DEPT- ECE SEM- 6TH ROLL- 32
Wavelength  division  Multiplexing : ,[object Object],      carrier signals on a single optical fiber by using different       wavelengths of laser light to carry different signals. ,[object Object],    > Coarse WDM     > Dense  WDM
What  is  dwdm ?? > Dense wavelength division multiplexing (DWDM) is a     technology that uses more than eight multiplexed signals     to transmit many wavelengths of light simultaneously     over a single optical fiber .
HISTORY OF DWDM :: 64 to 160 channels in 1550 nm window Next generation DWDM  system Channel  spacing  of  0.2  to  0.4 nm 16 to 40 channels in 1550nm window DWDM (Dense  wdm) Channel  spacing of 0.8 to 1.6 2 to 8 channels in 1550nm window Passive (or) 2nd generation WDM Channel spacing of~ 3.2nm 2 channels WWDM (Wideband WDM) 1310nm & 1550nm Late 1990’s       Mid  1990’s                Early          1990’s   1980’s
A dwdm system:: *A basic DWDM system contains several main components: (a) A DWDM terminal multiplexer (b) An intermediate line repeater  (c) An intermediate optical terminal (d) A DWDM terminal demultiplexer (e) Optical Supervisory Channel (OSC)
Block  diagram  of  dwdm  system ::
Itu-tg :: ,[object Object],  structure, though some vendors have opted to use 100 megabit    Ethernet or another signal format. ,[object Object],  may also perform  forward error correction (FEC)  via 'digital wrapper'   technology, as described in the ITU-TG.709 standard. ,[object Object],  with older but more standard SONET/SDH systems.
WAVELENGTH  CONVERTING TRANSPONDERS :: ,[object Object], wavelength of a client-layer signal into one of the DWDM system's  equivalent internal wavelengths. ,[object Object], on the additional function of signal regeneration.   Signal regeneration in transponders quickly  evolved  through  1R    to   2R   to   3R . 1R                        2R                             3R   Retransmission                           Re-time,                                                               Re-transmit  Re-time, Re-transmit, Re-shape
RECONFIGURABLE OPTICAL  ADD-DROP  MULTIPLEXER :: ,[object Object],  for the dropping and adding of certain wavelength channels. Adding or   dropping wavelengths requires manually inserting or replacing   wavelength-selective cards.
OPTICAL CROSS CONNECTS:: (OXC) ,[object Object],  interconnection device is needed to route the signals from an input    port to the desired output port.These devices are called optical  crossconnectors(OCXs).Various categories of OXCs include electronic,   optical, and wavelength selective devices.
CHANNEL  SPACING :: ,[object Object],    multiplexed signals is known as the Channel Spacing. Since the      wavelength of operation is inversely proportional to the frequency,      a corresponding difference is introduced in the wavelength of each      signal.
CATeGORIES OF WAVELENGTH SWITCHeS:: ,[object Object]
Wavelength-Independent Reconfigurable switch.
  Wavelength-Selective Reconfigurable Switch.
  DWDM , ideally it should have additional optical switching capability   to implement dynamically reconfigurable interconnections necessary     for the next generation systems.
SONET WITH DWDM :: ,[object Object],  investments can be preserved. Often new implementations can   eliminate layers of equipment. SONET TERMINAL WDM OC-n FIBER OC-48C ATM SWITCH OC-48C LAYER -3 SWITCH
DWDM-FM :: ,[object Object],owned by Eagle Broadcasting Corporation in the Philippines. The  station's studio was located in EDSA, Quezon City and its transmitter   located at Commonwealth Avenue, Quezon City.
IP OVER DWDM :: * The problem:  The explosive growth of the Internet spurred by high     speed access networks and flat-rate mobile billing plans has caused    ferocious competition in the telecom service provider market. * Solutions:  One potential answer is IP over DWDM.
REQUIRMENTS IN THE  METROPOLITAN AREA :: ,[object Object],   respects from those in the long-haul network market.   > Some key requirements for DWDM systems in the MAN include       the following----   •  Multiprotocol support   •  Scalability   •  Reliability and availability   •  Openness (interfaces, network management, standard fiber types,electromagnetic compatibility)   •  Ease of installation and management   •  Size and power consumption   •  Cost effectiveness
VALUE OF DWDM IN  METROPOLITAN  AREA :: ,[object Object],Then the equipment savings made it the solution of choice for new long-haul routes, even when ample fiber was available. Alternatives  for capacity enhancement exist, such as pulling new cable and SONET overlays, but DWDMcan do more.
WHY  DWDM ?? ,[object Object],   potentially unlimited transmission capacity is the most obvious    advantage of DWDM technology. The current investment in fiber plant    can not only be preserved, but optimized by a factor of at least 32.   capacity can be obtained for the cost of the equipment, and existing  fiber plant investment is retained.
benefits  OF  DWDM :: ,[object Object]
