Kebal kay madhyam sey internet par data kaa transmission kaise kam karta hai? aur yeh prakar?

kebal kay madhyam sey internet par data kaa transmission kaise kam karta hai? aur yeh prakar?

transmission media network kay sanchar madhyam iska matlab hai ki kanekshan kebal kanekting media kebal kay bare mein baat key jaa rahi hai joe do yaa do sey adhik varkasteshan ko jodta hai, usey sanchar channel kaha jata hai

lan kay sthaniya kshetr network mein joe bahut chhote network hain, kai alag-alag prakar kay media hain joe mud jodi kay roop mein tambe kay kandktar kaa upayog karte hain yaa ab tak kay sabse aam hann hal hee mein lan mein optical fiber proudyogiki kay upayog par bahut gambhirata sey vichar kia gaya hai ।

anya media udaharan maikrovev transmission infrared telephone line adi kaa bhi upayog kia jata hai jab hum sanchar media ko nirdeshit media yaa vayar proudyogiki aur anirdeshit media yaa wireless technologies shreniyon mein samuhit kr sakte hann nirdeshit media mein kebal shamil hain aur anirdeshit media mein hava kay pani yaa vacuum kay madhyam sey lehren shamil hann
kebal nirdeshit media kay buniadi prakar kay nichey charcha key jaa rahi hai:-

nirdeshit media hain (maikrovev radio tarangen aur upagraha)

mud jodi kebal kya hai?

data sanchar mein pahanane kaa sabse aam roop avedan mud jodi kebal yeh ek dabl helix roop mein ek saath do saman taron jaal kay hote hain ।

mud kebal kay vibhinn prakar aur shreniyan maujood hain, leikin un sabhi mein do chizen aam hain:-
1- jode mein taar amma
2- taron kay jode ek-doosare kay charon ore mud jate hann

kate5 aur kate6 kay roop mein jana jane vala ek vishesh prakar kaa mud jodi kebal jyadatar vishisht prakar kay deepak mein upayog kia jata hai arthat ethernet islie ise ethernet kebal kay roop mein bhi jana jata hai

taar kay ghumav crostock come kr deta hai signal hastaxep kay rupon ko crostock kaha jata hai ।

labh

ise sthapit karna aur banae rakhna saral aur asan hai
yeh bhautik hai
yeh lachila aur come vajan vala hota hai
ise asani sey joda jaa sakata hai
yeh bahut mahanga hai

nukasan

is tarah kay fayde honey kaa devata nahin hai ki mud jodi kebal kay data transmission visheshataen itani achchi nahin hain ki yeh kya fayde hain:
ucch kshinata kay karan hann yeh repeater kay upayog kay bina lambi duri par ek sanketh ley jane mein saksham hai
isamen come bandwidth kshamataen hain joe ise broadband eplikeshan kay liye anupayukt banati hann
yeh condition kay saath 1 mbps aur 10 mbps key adhikatam data dar ko support karta hai

 

koksiyal kebal kya hai aur iske fayde aur nukasan kya hain?

yeh ek prakar kaa kebal hai jisamen taar dhal kay liye ek yaa adhik sey ghira ek thos taar core hota hai iid plastic insulator kay kuch prakar sey alag bhitari core sanketh kia jata hai aur dhal jamin pradan karte hai aur coaxial kebal hai bijli kay gun hai aur ucch gati sanchar kay liye upayukt hai, jabaki yeh mud jodi yeh vyapak roop sey television sanketo kay liye prayog kia jata hai key tulana mein come lokapriya hai ।

koksiyal kebal key data transmission visheshata vastav mein mud jodi kebal sey behtar mana jata hai

koksiyal kebal kay faydei

koksiyal cables key data transmission visheshata mud jodi kebal key tulana mein kafi behtar hai
is sajha kebal network kay adhar par koksiyal kebal kaa istemal kia jaa sakata hai ki kebal kaa istemal broadband transmission kay liye kia jaa sakata hai ।
yeh kai chainlon hai aur jaisa ki aap ek saath kaha istemal kia jaa sakata hai ।
isamen 400 mbps tak hai offer bandwidth hai
ek optical fiber kya hai?

optical fiber mein kanch yaa kanch key ek patali kismen hoti hain jaise ki ek samagri joe itani nirmit hoti hai ki ve detector kay madhyam sey fiber kay doosare chhor tak ek srot sey prakash ley jaa sakte hann

prakash srot kaa upayog yaa to prakash utsarjak diode led leisure diode ld kay data kay roop mein kia jaa sakata hai jise preshit kia jana hai, freecvensee modulation takanikon kaa upayog krake prakash beam par sangrahak kia jata hai mul sanketh prapt ant mein uthaya jaa sakata hai aur madhyam key bandwidth ko 20 aur 150 mbps kay beach led is renj kay liye sambhavit roop sey bahut adhik hai lds kaa upayog krake sambhav hai

fiber kebal mein tin tukade hote hain:-

1-core-glass yaa plastic seva prakash yatra
2- clading- joe core kaa ek kavar hai joe core ko wapas prakash ko darshata hai
3- surakshatmak coating – joe fiber kebal ko shatrutapoorn vatavaran sey bachata hai

labh

yeh vidyut aur chumbakiy hastaxep kay liye pratiraksha hai joe kissi bhi roop mein shore hai kyonki janakari sangrahak prakash beam par yatra kr rahi hai
yeh harris audyogic vatavaran kay liye atyadhik upayukt hai
yeh bahut adhik pareshan kshamata kay saath surakshit sancharan key guarantee bhi deta hai
fiber optic kebal kaa upayog broadband transmission kay liye kia jaa sakata hai jahan kai channel joe samanantar mein handle key avritti kay bande hain aur jahan sthiti pareshan chainlon ko poora karna bhi sambhav hai joe doorbeen graphics tv aur dhwani kay liye channel hann

nukasan

sthapana key samasya fiber optic kebal kafi nazuk hain aur karyalay kay vatavaran kay liye paryapt roop sey majaboot lene kay liye vishesh dekhbhal key avashyakata ho sakti hai

yaa to fiber sey ek saath judna yaa fiber sey halka srot lagana kathin prakriya hai ।
shore pratiraksha optical fiber kay karan lagabhag asambhav hai taki sanketh mein fiber ko katana chahiye aur detector dala jana chahiei
prakash receiver ko charan sey bahar tak pahunch sakata hai
kanekshan nukasan aam samasyayen hain fiber optic kebal milap kay liye adhik kathin hain
