Kor u qaadista Calaamadda Moobaylka ee Tunnel-ka: Istaraatiijiyadda ku celcelinta Fiber Optic-ga ee Awoodda Sare leh ee Lintrate

Dhismaha tunnel waddo weyn oo 2.2 km ah oo ku yaal Shenzhen, meelaha aan la isku halleyn karin ee isgaarsiinta ayaa halis geliyay inay hakad galaan horumarka. Inkasta oo qodistu ay gaartay 1,500 mitir, calaamadda moobaylku way libdhay ilaa 400 mitir, taasoo ka dhigtay isku-duwidda shaqaalaha mid aan macquul ahayn. Iyada oo aan lahayn isku xirnaan deggan, warbixin maalinle ah, hubinta badbaadada, iyo cusbooneysiinta saadka ayaa istaagay. Marxaladdan muhiimka ah, milkiilaha mashruucu wuxuu u jeestay Lintrate si uu u keeno xal furaha ah oo dammaanad qaadi doona calaamadda moobaylka ee aan kala go 'lahayn ee aagga shaqada oo dhan.

Iyada oo ka faa'iideysanaysa waayo-aragnimadeeda ballaaran ee kaabayaasha isgaarsiinta, Lintrate waxay si degdeg ah u soo ururisay koox naqshadeyn iyo hawlgelin u heellan. Ka dib markii ay la tashatay macmiilka iyo sahan qoto dheer oo ku saabsan xaaladaha juqraafiyeed iyo RF ee goobta, kooxdu waxay doorataynidaamka soo celinta fiber optic-ka ee awoodda sare lehsida laf-dhabarta mashruuca.

Jaantuska Shaxda

Tijaabooyin hore oo laga sameeyay bogga internetka ayaa muujiyay in qiimaha SREP ee calaamadda isha uu ka hooseeyay -100 dBm (halkaas oo -90 dBm ama ka sareeya ay tilmaamayso tayo la aqbali karo). Si looga gudbo tan, injineerada Lintrate waxay u wareegeen anteeno qaab guddi ah si ay u kordhiyaan faa'iidada soo dhawaynta, iyagoo hubinaya in la geliyo wax soo saar adag oo loogu talagalay shabakadda ku celcelinta.

anteeno dibadda ah

Qalabka asaasiga ah wuxuu isticmaalay laba-xagal, oo ah 20 W fiber optic repeater. Cutubka Saldhigga wuxuu ku yaallay albaabka tunnelka, halka Cutubka Fog uu ku noolaa gudaha 1,500 mitir. Qaybiye 5 dB ah, oo laba-geesood ah ayaa calaamadda la ballaariyay ku wareejiyay marinnada isgoysyada, iyadoo anteenooyin waaweyn oo guddi ah ay gadaal u laabanayaan si ay labada dhinac ee godka tunnelka u daboolaan.

Cutubka Saldhigga ee Ku-celcelinta Fiber Optic

Si la yaab leh, shaqaalaha Lintrate waxay dhammaystireen rakibidda hal maalin gudaheed, subaxdii xigtayna, tijaabintu waxay xaqiijisay inay si buuxda u hoggaansamayso shuruudaha waxqabadka macmiilka. Isbeddelkan degdegga ah ma xallin oo keliya go'itaanka calaamadda moobaylka laakiin sidoo kale wuxuu yareeyay carqaladaynta jadwalka tunnel-ka, isagoo kasbaday ammaan sare milkiilaha mashruuca.

Cutubka Fog ee Ku Celinta Fiber Optic

Si mustaqbalka loo ilaaliyo shabakadda, Lintrate waxay hirgelisay naqshad dabacsan oo aan dib loo dhigin oo u oggolaanaysa Unugga Fog iyo anteenooyinka ku jira godka in dib loo habeeyo marka qodista qodista ay sii socoto. Marka godku sii fido, hagaajinta duulimaadka waxay ilaalinaysaa daboolid aan kala go 'lahayn, taasoo hubinaysa in shaqaaluhu ay had iyo jeer helaan isgaarsiin lagu kalsoonaan karo.

Anteenooyinka Gudaha

Iyada oo leh 13 sano oo khibrad ah iyo dhoofin loo sameeyay in ka badan 155 waddan,Lintrateis soo-saare hormuud ahof xoojiyeyaasha calaamadaha moobaylka ganacsiga, ku celceliyeyaasha fiber optic-ga, iyo nidaamyada anteenada. Rikoorkeenna la xaqiijiyay ee ku saabsan xaaladaha kala duwan ee mashaariicda ayaa naga dhigaya lammaanaha lagu kalsoon yahay ee caqabad kasta oo ku timaadda tunnel ama kaabayaasha dhaqaalaha.
