Optical fiber Losses
We have already discussed Optical fiber, Power meter and OTDR in our previous videos. Today we will focus on fiber losses only. Fiber Optic Comm Fiber optic cable is lighter, smaller and flexible than copper cable. It can transmit optical signal with faster speed over longer distance. Many factors can influence the performance of… -

Refraction of Light
Refraction of Light Bending of light when it enters from one optical medium to another is called refraction of light. Light travels with different speeds in different transparent medium.Its speed in air is 3×108 m/s and 2×108 m/s in glass.…
Reflection of Light
Reflection of Light After striking with a surface, Return of light, Sound, Wave or any body is called reflection. Light rays travel in straight line.In physics, we use straight lines with arrows to represent paths of light.The arrows represent the…
OTDR Optical Time Domain Reflectometer
OTDR | Optical Time Domain Reflectometer OTDR Optical Time Domain Reflectometer is used to check the performance of fiber optic link and detect problems. It is used to create a virtual picture of a fiber optic cable route. It is…
Satellite Communication
Satellite Satellite is an object that orbits or rotate around another object in a particular path Orbit. Our solar system is a good example. How satellite stable in orbit? A satellite remains in orbit because the centrifugal force caused by…
Infrared IR
Discovery of Infrared In 1800, William Herschel conducted an experiment measuring the difference in temperature between the colors in the visible spectrum. Infrared is a section of invisible light on the electromagnetic spectrum. It’s a form of radiant heat that can…
ISM Frequency Band
ISM Frequency Band The ITU (International Telecommunication Union) had originally reserved a portion of the RF spectrum globally for industrial, scientific and medical applications. Such as process heating, microwave oven, and medical diathermy equipment etc. The main feature of the…
FTTH Fiber to the Home
FTTx is a access network technology that uses optical fiber directly from the central point to the Home. FTTx offers triple play services voice, video and data.
Transmission medium
Transmission Media It is a path through which information signal travels from source to destination. It is also known as Transmission Line or Transmission channel. It is further divided into two categories Guided Media. Unguided Media. Guided / Bounded /Wired…
Noise
Noise Noise or Electrical Noise is any unwanted electrical signal interferes or distorts the information signal. It affects the signal inside or outside the equipment and generates error. It affects both analog and digital signal and quality of information signal…
Modulation and Demodulation
Modulation and demodulation are fundamental processes in telecommunications that involve the encoding and decoding of information onto a carrier signal.
