Single Mode & Multimode Fiber Optics 1.2

Hi Readers,

I continue My previous blog

Let's First I tell you about Low Water Peak (LWP) & Polarised Mode Dispersion (PMD)

Low Water Peak (LWP): - In production of Fiber Optics used optic Material Low Water peak Value is added for cause of Attenuation & Dispersion in propagate wavelength.

Polarised Mode Dispersion (PMD):- After Propagate wavelength From Transmitter of Fiber Optics, The Light wave which converted Electromagnet to Light wave Travel through Fiber optics Attenuation & Dispersion occurs due to two Orthogonal Polarised Mode.

So above these two categories ITU-T Create Different Categories of G.652 Fiber. Presently There are four Categories A, B, C, D (G.652A, G.652B, G.652C, G.652D)

Below Table Shows:-

Where PMDQ link design value Specification and Water peak is Specified (LWP) or Not Specified (WPNS)

Category	Maximum PMDQ (ps/km 1/2)	Water Peak
A	0.5	WPNS
B	0.2	WPNS
C	0.5	LWP
D	0.2	LWP

Single Mode & Multimode Fiber Optics 1.1

HI Readers,

Today I am writing about Single Mode & Multimode Fiber Optics.

Multimode Fiber Optics (MMF):- Earlier in 1980's This Type of Fiber Optics Series Standard start with ITU-T G.651.

Wherein ITU-T G.651 having 50μm Nominal Core Diameter & 125μm nominal Cladding diameter. ITU-T G.651 Optics Used only for 10km.

ITU-T G.651 this Configuration deleted due to Large Connectivity required,

after Devloped of  ITU-T G.651.1 Multi Mode Fiber optics Greded index.

ITU-T G.651.1 is suitable to use in the 850nm (nano-meter) & 1300nm.

Singlemode Fiber Optics (SMF):- The ITU-T developed new Fiber Optics Characteristics Which is ITU-T G.652 Single Mode Fiber Optics Called Standard Single Mode Fiber. Having 8-10μm Nominal Core Diameter & 125μm nominal Cladding diameter 

This SMF series starts with G.652 to G.657.

ITU-T G.652 is suitable to use in the 1310nm (nano-meter) & 1550nm for High Performance Optical transmission System.

Fiber Optics Attributes 1.1

Hi Readers,

In MY previous blog I write about Fiber Optics attribute, Now I just explain some attribute.

• Macrobending Loss :-  Macrobending Loss occurred when fiber optics psychically Bent. 

• Chromatic Dispersion :- Firstly Dispersion, It's a time domain for Spreading or Broadening of signal. because its occurring in fiber optics we can say its Chromatic Dispersion due to Fiber Optics material. When an Ideal wavelength Travel in Fiber Optics due to Material Characteristic Spread or Broad The Ideal Signal.

Fiber Optics Attributes

Hi Readers,

Today I tell you About Fiber Optics Attributes

   

1.                Fiber Attributes : - These Attributes are Mainly Preferred by Manufacturer of Fiber Optics Cable. As in Core & Cladding Diameter, Macrobending Loss, Chromatic Dispersion.

2.                   Cable Attributes :- These Attributes Include Attenaution coefficient & Polarization Mode

 Dispersion (PMD) Coefficient.

3.                   Link Attributes :- Link Attributes are those which are Includes Transmitter To Receiver

 Connected With Fiber Optics Live Network.

Thank You 

I Continue This Series on Daily Basis.

Last Week Visitors i am very thankful to visit my blog. I can't Imagine it's a huge crowd here for Fiber Optics.

ITU-T G SERIES FOR OPTICAL COMMUNICATION - 1.2

Hi Readers,

in My previous blog tell you about Core , Cladding, and Coating and What is behaviour of them.

After Invention of Laser Technology It was suggested that optical fibres might be the best choice for using laser light for optical communications.

For Optical Communication, Below three of Them are necessary aspects 

1. A LIGHT SOURCE  like LED or Laser Which is Called Transmitter.

2. A LIGHT SENSER like PHOTO DIODE Which is Called Receiver.

3. MEDIA Connectivity Which is My Lovely Fiber Opic.

Thanks 

Please Share your feedback so i can make it more informative

Don't Loose previous blogs too, If this for you.

ITU-T G SERIES FOR OPTICAL COMMUNICATION - 1.1

Hello Readers,

I am talking about Types Of Fiber Optics & Why they Differ from Each Other, In My previous Blog I mentioned about CORE, CLADDING & BUFFER/COATING.

Previos Blog Link -

https://telecomwisdom.blogspot.in/2017/11/itu-t-g-series-for-optical.html


1. Single Mode                                                                          2. Multi Mode

Below Image can explain you why I am talking about about 3 of them.

       In Single Mode Optics We see Only a Ray Tansmit or Travel Without any Interfference,

But There is Core Diameter Is too Smaller Than Cladding.

       But Herein Multimode Fiber Optics has Two Branches, Step Index & Graded index.

These Type of Multimode Fiber Optics Due to its High Concentration of Material.

Single Mode has no Graded index Option.

Hope It will help you to Understand Fiber Optics Type.

Thank You .

ITU-T G SERIES FOR OPTICAL COMMUNICATION - 1

Hello Readers,

Let's Start About Types of Fiber Optics 

There are Two Types of Fiber Optics

1. Single Mode                                                             2. Multimode 



Before we talk about Single Mode & Multimode Fiber below image guide or help you to understand why Single Mode & Multimode Fiber Optics.

There are 3 Words are using 

1. Core

This is Centre of    Fiber Optics Where Lightwave Travel Which is made of Glass or  Plastic.

2. Cladding

A Dielectric material which is overlaaped over Core (Glass), It Supprt & Protect to Travel Light.

3. Buffer or Coating 

Coating Or Buffer Part is Cover up Cladding to Protect Core & Cladding  From Outside.

Yes, I know why do i tell you about three of them , so they made the Difference Between types of Fiber Optics.

Continue Soon........

Thank You.

ITU-T G SERIES FOR OPTICAL COMMUNICATION

Hi Readers,

Firstly I have to say that Below Image is Mr. Narinder Singh Kapani Sir, Known as "Father of Fiber Optics"

Let's Start :- 

What is ITU-T ?

ITU-T Full Form :- INTERNATIONAL TELECOMMUNICATION UNION.

Why I am Talking about ITU-T. Every where on Planet Earth Without ITU-T Standard you Doesn't Imagine Telecommunication.

Communication with Fiber Optics :-

After Invention of Laser Technology It was suggested that optical fibres might be the best choice for using laser light for optical communications.

What is Optical Fiber ?

Now a days, Optical Fiber are used commonly in everywhere where communication is Required between two Electronics Equipment.

Optical Fiber is made of Glass High Quality /Silica  or Plastic.

Its Slightly Thicker Than Human Hair.

Because of It's Transparency We used it for Travel Light in it as Waveguide.

Thank You.

It's A Weekly Blog
