Optical Fiber Connectivity

Optical Fiber Connectivity

Fiber connectivity is the fastest communication media for data/Voice communication. Data communication speed in fiber is in gigabyte.  For fiber communication we require following components.

Now we will discuss about all above component in details:

1. First and Major Component for OFC connectivity is fiber cable:

     

A fiber-optic cable is a high-speed network cable, made up of strands of glass fibers. Generally there are                 

three types of fiber optic cable in use.

Fiber Optic Cable

•  Single mode Optical Fiber Cable
•  Multi mode Optical Fiber Cable
•   Plastic optical fiber or photonic fiber.

Note: Transparent glass or plastic fiber allows the guiding of light from one end to the other with minimal loss is the most efficient.1 G fiber/10G  Cable:

a)    Single Mode Optical Fiber Cable: Single Mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission.

b   b)    Multi-Mode optical Fiber Cable: Multi Mode cable  has a little bit bigger diameter, with a common diameters in the 50-to-100 micron range for the light carry component. Most of the applications in which Multi-mode fiber is used, 2 fibers are used. Distance between to points for Multimode connectivity is 500 meter.

c  c) Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer just like to glass optical fiber, transmits light through the core of the fiber. Its main advantage over the glass product that its robustness under bending and stretching.

Note: Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multi mode

2. SC Pigtail 9/125 Single mode:

A fiber pigtail is a single, short optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk.

                   

              

 Note: Total pigtails require as per OFC cable core. And for single mode fiber cable we use single mode pigtail and for multi mode we will use multi mode pigtail. Generally the color of single mode pigtail is yellow and multi mode pigtail is orange

3. SC Flange Single mode/Multi mode or  Fiber Optic FC Coupler

Fiber Optic SC Flange  or  Adapter, SC-SC Single mode Simplex / SC-SC Multimode Simplex. Normally used to fiber optic cables with standard SC (male) connectors.

 

Pigtail                                  Adapter

Note: SC Flange Single mode/Multi mode Fiber Optic FC Coupler will fix in SC 6 Port Adapter Panel and this panel will fix in to LIU Adapter Panel SC Flange Single mode

Adapter

4. LC-SC Duplex Fiber Patch Cord

LC Fiber Optic Patch Cord. LC stands for Lucent Connector.LC connector is a small form-factor fiber optic connector and was developed to replace SC connector due to their smaller size. (LC is only half the footprint of SC connector).

                                            Multi Mode                          Single Mode 

5. Fiber Optic Transceiver : 

This also was known as Fiber Optical Transceiver, Optical Module, Optics Module etc. It is a single, packaged device that uses fiber optic technology to transmit and receive data. 'Transceiver' is a combination of two words, transmitter' and 'receiver'. We connect(insert) this module in to switch’s SFP port.

                          Fiber Optic Transceiver            Switch with SFP Port

Note: SFP (Small form-factor plug gable ) devices are hot-swappable interfaces used primarily in network and storage switches. The SFP ports on a switch and SFP modules enable   

the switch to connect to fiber and Ethernet cables of different types and speeds.

5. LIU  Unit

LIU box is Smaller basic patch panel & cabinet used in interconnecting, cross-connecting. The LIU (optical fiber interconnecting unit) is modular and suitable for optical cable installation, bare fibers splicing & protection, pigtails storage & management.

Introduction of Haridwar's Chauhan All Chauhans in Haridwar are Rajputs Hindus migrated from Rajasthan and some are also following Sikhism.

The Chauhan Rajputs have a dominant role in Haridwar district of Uttrakhand. Haridwar is also known as Chauhan Puri in local area. All Chauhans are among of 52 villages near Rajaji National Park. Kuldevi of Chauhan Rajputs is Maa Shakumhra Devi in District Sahranpur. In month of Bhadrpad Chauhans go to worship Gogaji (JAHAR VEER GOGA PEER, Ancient great warrior ruler of CHAUHAN dynsnty GOGAJI DEV CHAUHAN) in Rajasthan. Chauhans of haridwar having big role in Land and farming in District. Mostly Chauhans of Haridwar having gotras Vats,Gahadwal,Budhwal, Kachwaha,Bhaliyan, Gahlaut, Bhadauriya,Samiyan , Kashyap,Jagharan and solanki gotra etc. and their marriage system is on the basis of the gautra as well as in other rajput clans. All Chauhans are from Agnivansha.

 
About

Chauhans are well known for their bravery in the Region.All Chauhans are living in the region from late of 17th Century and was divided in several groups later on these groups are formed as villages and people are started to involve in farming. Villages of Chauhans are known here in terms Khadar,Bhood and pachha. The villages area near bhadrabad and between laksar to haridwar are known as Khadar, Villages near Dhanauri and bhagwanpur known as Bhood and villages near shakumbhra devi known as pachha. By efforts of Dr. Pyarelal Chauhan Samrat Pritviraj Chauhan Degree College come in existence in bhadrabad providing national level education with different courses.
