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.
