What is the principle of OTDR?

An optical time-domain reflectometer is test equipment used to evaluate the loss of signal inside an optical fiber by transmitting laser pulses inside the fiber and measures the scattered light signal.

As we can see in the figure shown above the OTDR Machine contains a light source (mainly a laser) and a receiver along with a coupler or circulator. The coupler is connected with the fiber under test through a front panel connector.

The laser produces a short and intense light beam. These pulses are directed into the fiber link under test through a fiber optic coupler. A coupler splits the transmitted light pulse into two halves. Due to this, not all the transmitted pulse is directed inside the fiber.

However, despite using a coupler if we use a circulator then this wastage of transmitted signal can be avoided. As circulators are highly directional devices that direct the overall light signal into the fiber as well as sends the reflected or scattered light signal into the detector.

By inserting circulators in the operational unit of fiber optic tester, the dynamic range of the equipment can be improved. However, it also causes the overall cost of the system to increase considerably as the circulator is highly expensive in comparison to couplers.

Why Celebrate shivratri 2020?

The festival is celebrated on the new moon day in the month of Maagha according to the Hindu calendar. The day is celebrated to venerate Lord Shiva, an important deity in Hindu culture.

Maha Shivratri is a Hindu festival which is celebrated by people following Hinduism in India. People often fast on the night of Shivratri and sing hymns and praises in the name of Lord Shiva. 

Hindu temples across the country are decorated with lights and colorful decorations and people can be seen offering night long prayers to Shiva Lingam. Wood apple leaves, cold water, and milk are offered to the Shiva Lingam on this day as they are believed to be Lord Shiva's favorite.

It is believed that the people who fast on this night and offer prayers to Lord Shiva bring good luck into their life. 

The most popular Maha Shivratri celebrations take place in Ujjain, believed to be the place of residence of Lord Shiva. 

Large processions are carried out throughout the city, with people thronging the streets to catch a glimpse of the revered idol of Lord Shiva.

Wishing you very Happy Shivratri 2020 from Spec technology Corp. & Candid Optronix Family.

Do you understand about FTTx technology?

FTTX Stands for Fiber to the X or Stands for fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications.

FTTX is a generalization for several configurations of fiber deployment, arranged into two groups: FTTP/FTTH/FTTB (Fiber laid all the way to the premises/home/building) and FTTC/N (fiber laid to the cabinet/node, with copper wires completing the connection).

Do you understand Single mode Fiber (SMF)?

Single-Mode Fiber (SMF):

Single-mode fiber is a mode of light and it is used for long-distance signal transmission which is through the light travels on the optical fiber. It is also called as uni-mode fiber, mono mode fiber, and single-mode optical wavelength.

These modes define the way the wave travels through space, for Example how the wave is distributed in space.

Waves can have the same mode but have different frequencies. This is the case in single-mode fibers, where we can have waves with different frequencies, but of the same mode, which means that they are distributed in space in the same way, and that gives us a single ray of light. Although the ray travels parallel to the length of the fiber.

Although the ray travels parallel to the length of the fiber, it is often known as transverse mode since its electromagnetic oscillations occur perpendicular (transverse) to the length of the fiber.

The Structure of a typical single-mode fiber.

 1. Core 8 - 9 µm diameter
 2. Cladding 125 µm diameter.
 3. Buffer 250 µm diameter.
 4. Jacket 900 µm diameter.
