Step Index Optical Fiber - Multi Mode and Single Mode Step Index Fibers - Step Index Optical Fibre

[@notrushi]

tomorrow is my paper i m glad that i found you!!!

[@EngineeringMadeEasy]

And I am glad that that I could help you in some way. Thanks dear

[@priyac2315]

Same Yenakum 2mrw exam

[@benozachariah7524]

All videos are helpful brother...So handsomely made for all categories of students....May God bless you..

[@EngineeringMadeEasy]

Thank you so much dear for your kind words

[@Sanhyadri]

sir.... u r d best

[@EngineeringMadeEasy]

Thank you so much 😊

[@professionals-magnacarta8650]

tq for this video its really useful and awesome.

[@EngineeringMadeEasy]

+SUVALAKSHMI A welcome

[@techmahfuzbd]

Informative video for communication engineering student

[@EngineeringMadeEasy]

Thank you so much...keep watching for more

[@user-si5pp6jr1i]

good but you have to write all this lecture already and explained it.

[@EngineeringMadeEasy]

+Tenzin thinley yes...I have already started using ready made notes. You may visit my channel for my recent uploads. Thanks

[@dhrwilliams8624]

I was about to say the same thing

[@El650Jefe]

What do you mean by mode though? Is a mode just different paths a ray can take along a fiber? So if you have various rays (all of the same wavelength) and they’re traveling along different paths then you have multiple modes? Or what if you have rays of different wavelengths does that mean you have various mode? I’m just confused as to is it the path, wavelength, or both that determines if you have various modes.

I guess multimode has greater bandwidth than single mode min. 22:44

[@EngineeringMadeEasy]

No...Single mode has more Bandwidth...For your satisfaction you may search the internet to clear your confusion. Thanks

[@priyac2315]

Tq very usefull

[@EngineeringMadeEasy]

You are welcome 😊

[@11-khandagalerutuja85]

Tq so much sir

According to the Numerical aperture formulae, it does not depend on the radius of core. Then why is the NA of Multi mode fiber greater than Single mode fiber? Any other reason that might affect the NA?

[@hatimkhan913]

i didn't get it step index fiber is it all about thickness i thought in step index fiber index very with redius of core

[@EngineeringMadeEasy]

No, index varies with radius in case of graded index fiber.

[@hatimkhan913]

is the only size is different in single mode and multimode step index fiber

[@mohamedyasin2864]

it nice explanation but in single mode index why you drawn only one straight line or it strike to the the walls of core

[@EngineeringMadeEasy]

+mohamed yaasiin Hi...As the thickness of single mode fiber is so small that it allows only single mode to propagate through it. And Total Internal Reflection happens in single mode fiber also, Otherwise that particular guided mode would have been converted to leaky mode, hence leaving the optical fiber.

[@mohamedyasin2864]

ok lecturer thank you

[@EngineeringMadeEasy]

+mohamed yaasiin welcome

[@WaqasAhmed-xs8wk]

by mode of light you mean multiplexed signal or just one signal?

[@EngineeringMadeEasy]

+Waqas Ahmed Mode here is of single mode and multi mode types, depending on whether single or multiple light rays propagate through the fiber.

Which kind of taulrance is higher in MMOP

[@jayasree3019]

In step index fiber chromatic dispersion is it true

[@krishnavenisidigonde5069]

What is Multimode graded index fiber ?

[@EngineeringMadeEasy]

A multimode graded-index fiber has a core of radius (a). Unlike step-index fibers, the value of the refractive index of the core (n1) varies according to the radial distance (r). The value of n1 decreases as the distance (r) from the center of the fiber increases. The value of n1 decreases until it approaches the value of the refractive index of the cladding (n2). The value of n1 must be higher than the value of n2 to allow for proper mode propagation. Like the step-index fiber, the value of n2 is constant and has a slightly lower value than the maximum value of n1. The relative refractive index difference (Δ) is determined using the maximum value of n1 and the value of n2.

[@tamannafathima7799]

U are explaining in good way but u are toooo slow u draw the structures very very late

[@parasapraveena122]

Tooo long video

[@gouravjangra6548]

Speak hi hindi.... Boring lecture try to make interesting...

[@EngineeringMadeEasy]

Ok, I will try to make it better

[@shiva-bg6ve]

Very slow waste hey
