DWDM Dense Wavelength Division Multiplexing

Dense Wavelength Division Multiplexing DWDM 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…
Computer Ports

  Computer Ports Computer ports or Motherboard I/O interfaces are used to connect external devices to the computer. These interfaces are mostly located on the back side of the motherboard. Number of Interfaces depends on the size of Motherboard and technology…
SDH Synchronous Digital Hierarchy

  SDH synchronous digital hierarchy. It is a transmission method. This method is used in optical fibre transmission system called SDH system. We have already discussed the basic concepts of the transmission system. This video will give you the basic concept…
PDH Plesiochronous Digital Hierarchy

PDH Plesiochronous Digital Hierarchy PCM Pulse code modulation is the basic block for PDH SDH and SONET. Sampling frequency must be twice the higher frequency component of the signal. Voice frequency sampling rate 8KHz (0.3 to 3.4 KHz = 4KHz). Each…
Optical Fiber

OPTICAL FIBER Optical fiber is a type of guided medium to transport information from one point to another point.Information travels in the form of light.Data capacity of fiber is very high due to light nature of the signal.It has some…
