Falanqaynta tilmaamayaasha muhiimka ah ee mitirka korantada indhaha

August 19, 2022

Nidaamyada optic optic-ga, cabbiraadda afka indhaha ayaa ah kuwa ugu aasaasiga ah, oo u eg kuwa badan oo ku saabsan elektiroonigga. Cabbirka fiber optic-ga, mitirka visatical korantada waa mitir guud oo culus. Iyada oo lagu cabiro awoodda buuxda ee gudbiyaha ama shabakadda indhaha, mitir koronto oo indhaha ah ayaa qiimeyn kara waxqabadka qalabka indhaha. Adeegsiga mitir koronto oo indhaha ah oo isku darka ilo deggan, waxaa suurtagal ah in la cadeeyo luminta isku xirka, xaqiijinta sii wadida, oo ay ka caawiso qiimeynta tayada iskuxirka fiberka.

Waa maxay mitirka korantada indhaha? Mitirka korantada indhaha ee indhaha loo isticmaalo waxaa loo isticmaalaa in lagu cabiro awoodda indhaha ee dhagaxa ah ama luminta qaraabada ee korantada indhaha iyada oo loo marayo dherer fiber optic ah.

Markaad xulato mitirka korantada indhaha, tilmaamaha farsamada ee ugu muhiimsan waa hirarka iyo tirada imtixaanka. Unugga awoodda indhaha ee DBM waa DBM. Faahfaahinta tilmaanta indhaha ee indhaha ama beddelka, waxaa jira iftiinkeeda oo helitaanka awoodda indhaha. Guud ahaan, iftiinka iftiinka ayaa ka yar 0 DBM. Awoodda ugu yar ee indhaha ee ah in dhamaadka la helo ayaa la siin karaa waxaa loo yaqaan dareenka, iyo awooda ugu badan ee lagu heli karo laga jaro. Cutubka Qiimaha Dareenka waa dB (dBM-dBM = DB), oo loo yaqaan kala-duwanaanta firfircoon, iyo awoodda iftiinka ee iftiinka leh ee heysashada ee hela-galinta waa qiimaha apps la ogolaan karo. Awoodda dhabta ah ee iftiinka waqtiga imtixaanka ee laga jaray qiimaha ay runtii heshay koronto dhabarta ah. Waa luminta fiber (DB). Qiimaha ugu wanaagsan ee awoodda indhaha ee lagu helo dhamaadka helitaanka waa awooda ugu badan ee indhaha ee la heli karo - (kala-duwan / 2), laakiin guud ahaan ma fiicna. Sababo la xiriira firfircoonida mid kasta oo muuqaal ah oo muuqaal ah oo muuqaal ah iyo module optical thrus-ka ayaa ka duwan, sidaa darteed qaddarka gaarka ah ee fiber-ka ayaa u oggolaan kara in la istcimaalo ay kuxirantahay xaalada dhabta ah. Guud ahaan, yaraanta la ogolaan karo waa qiyaastii 15-30BB.

Qaar ka mid ah faahfaahinta milifyada milifyada korantada indhaha ee indhaha ayaa leh kaliya laba cabir oo ah awooda iftiinka iyo masaafada is-qaadista. Mararka qaarkood, masaafada lagu gudbin karo ee lagu xisaabiyo yareynta halkii kiiloomitir ee fiberku badanaa waa 0.5db / km. Masaafada ugu yar ee lagu faafiyo waxaa loo qaybiyaa 0.5. Awooda ugu badan ee indhaha ee la heli karo. Haddii awoodda indhaha ee la helo ay ka sarreyso qiimahan, Transceifechipifechie-ka indhaha ayaa laga yaabaa inuu gubto. Maanta ugu badan ee gudbinta ugu badan ee loo qaybiyey 0.5 waa xasaasiyadda. Haddii awoodda indhaha ee hela ay ka hooseyso qiimahan, xiriiriyaha ayaa laga yaabaa inuusan shaqeyn doono.

Waxaa jira laba siyaabood oo lagu xidho fiber:

Mid waa xiriir go'an, mid waa xiriir firfircoon, oo xiriirkii go'an ayaa ah iskuxirka iskuxiran. Xiriirka gaarka ah waa soo bixitaan, fiber-ka indhahana wuu dhalaalay si uu ugu xirmo labada fiilo ee indhaha. Faa'iidada ayaa ah in wax kululayntu ay yar tahay, oo dartiisu tahay in qalliinku yahay mid dhib badan oo dabacsanaanta ayaa liita. Xiriiriyaha, sida caadiga ah doofaarka wuxuu ku xiran yahay ODF. Faa'iidada ayaa ah in * dabacsanaan fudud, mutanaantiisu ay tahay in wax-qabadku yahay mid ballaaran.

Guud ahaan marka la eego, hagaajinta xiriir firfircoon waxay u dhigantaa hal kiilomitir oo ah fiber. Helitaanka fiber-ka waxaa lagu qiyaasi karaa iyadoo ay kujirto isku xirnaansho go'an oo firfircoon, iyo hoos udhaca fiber kiiloomitirkiiba waa 0.5 dB. Haddii xidhiidhka firfircoon uu aad u yar yahay, qiimahu wuxuu noqon karaa 0.4 dB. Fiber fudud kuma jiraan xiriir firfircoon, waa la dhimi karaa ilaa 0.3db, qiimaha fikradda ah ee fiber saafi ah waa 0.2db / km; Caymiska, inta badan kiisaska, 0.5 ayaa ka fiican.
