Waa maxay WiFi5 ONU?,
,
LM240TUW5 dual-mode ONU/ONT ka codso FTTH/FTTO, si loo bixiyo adeega xogta ku salaysan shabakada EPON/GPON.LM240TUW5 waxay isku dari kartaa shaqada wireless-ka iyadoo la kulma 802.11 a/b/g/n/ac heerarka farsamada, waxay taageertaa 2.4GHz & 5GHz signal wireless sidoo kale.Waxay leedahay sifooyin awood xoog leh iyo dabool ballaaran.Waxay siin kartaa isticmaalayaasha amniga gudbinta xogta hufan.Waxayna ku bixisaa adeegyo TV oo qiimo jaban leh 1 CATV Port.
Xawaaraha ilaa 1200Mbps, 4-Port XPON ONT waxay siin kartaa isticmaalayaasha surfing internet oo aan caadi ahayn, telefoon internet ah, iyo ciyaaraha khadka ah.Intaa waxaa dheer, adoo qaadanaya anteenada jihaynta Omni-ka dibadeed, LM240TUW5 waxay si weyn u kordhin kartaa kala duwanaanta wireless-ka & dareenka, taas oo awood kuu siinaysa inaad hesho calaamadaha wireless-ka ee geeska ugu fog gurigaaga ama xafiiskaaga.Waxa kale oo aad ku xidhi kartaa TV-ga oo aad noloshaada kobcin kartaa.
ONU (Optical Network Unit) waa aaladda gudbinta indhaha ee loo isticmaalo nidaamka isgaarsiinta fiber optic oo leh laba hawlood oo kala ah “dirid” iyo “helid”.Waa qalab ku jira shabakad indhaha ah oo ku xidha fiilooyinka indhaha iyo qalabka isticmaalaha.Isgaarsiinta Fiber optic waa tignoolajiyada isgaarsiinta u adeegsata iftiinka sida calaamad Bellman, ONU waa mid ka mid ah qalabka ugu muhiimsan isgaarsiinta iyo gudbinta calaamadaha.Marka la barbar dhigo qalabka shabakada caadiga ah, ONU waxay leedahay laba sifo:
Marka hore, marka la eego isku xirnaanta jireed, ONU waxay isticmaashaa fiilooyinka fiber optic halkii ay ka isticmaali lahaayeen fiilooyinka shabakada dhaqameed.Sababtoo ah fiilada fiber optic-ga ayaa leh xawli sare oo gudbin ah, awoodda gudbinta xogta oo sareysa, iyo fogaanta gudbinta dheer, waxay aad ugu habboon tahay gudbinta xawaaraha sare iyo xawaaraha sare.
Marka labaad, ONU waxay isticmaashaa tignoolajiyada gaarka ah ee TDMA (Waqtiga Qaybinta Multiple Access) si ay si kalsooni leh ugu gudbiso xogta isticmaalayaasha kala duwan waqtiyo kala duwan si loo hubiyo xasiloonida iyo amniga gudbinta xogta.
Shuruudaha
Horumarka Qaramada Midoobay ayaa si weyn u dardargeliyay horumarinta isgaarsiinta.Baaxadda guud ahaan waxay leedahay saddex walxood oo soo socda:
1. Hel ballaca guriga
Intaa waxaa dheer, baahida dhijitaalka ah ee qoysaska casriga ah ayaa kordhay waxaana loo baahan yahay in loo diro macluumaad dheeraad ah goobta guriga, taas oo u baahan taageero degdeg ah oo hufan.Waagii hore, tignoolajiyada ADSL waxay lahayd xaddidaad xagga xawaaraha gudbinta, laakiin UN waxay isticmaashaa fiber optics si ay u gaadho isticmaaleyaasha dhamaadka ah.Waxay taageertaa xawaaraha ugu badan ee boqolaal megabits, kaas oo dabooli doona baahida loo diro tiro badan oo xog ah.
2. Gaadhida miyiga
Dhulka miyiga ah, marin-u-helidda xayndaabka dhaqameedku way adag tahay in la daboolo baahiyaha isticmaalayaasha sababtoo ah kaabayaasha xaddidan.Qaramada Midoobay waxay adeegsataa tignoolajiyada fiber optic-ga oo xogta u gudbisa masaafo dheer, iyadoo adeeg degdeg ah ka bixinaysa dhulka miyiga ah, isla markaana wax weyn ku soo kordhinaysa kaabayaasha dhaqaalaha ee Qaramada Midoobay.
3. Qaab dhismeedka ganacsiga
Marka la eego ganacsiga, marka xogta loo diro meelo kala duwan, ONU waxay fulisaa habab kala duwan oo kala duwan oo kala duwan, taas oo aan hagaajinaynin oo kaliya waxqabadka shabakada, laakiin sidoo kale waxay hagaajinaysaa amniga gudbinta xogta.shirkad.
mustaqbalka
Hadda, iyada oo la horumarinayo 5G, xisaabinta daruuraha iyo tignoolajiyada kale, shabakadaha dhaqameed ma dabooli karaan baahida sii kordheysa.Taas bedelkeeda, tignoolajiyada fiber optic-ga waxay leedahay faa'iidooyinka gudbinta xawaaraha sare, xasilloonida wanaagsan iyo baaxadda ballaaran.Sidaa darteed, ONU sida qalab la fidiyey waxay leedahay karti ballaaran oo horumarineed.Mustaqbalka, cilmi baaris dheeraad ah ayaa lagu sameyn karaa meelaha soo socda:
1. Tignoolajiyada la cusboonaysiiyay oo ka sii wanagsan si loo hagaajiyo qalabka iyo xawaaraha soo dejinta
Samee cilmi-baaris joogto ah oo ku saabsan tignoolajiyada laxiriirta, diiradda saara hagaajinta xasilloonida qalabka, kordhinta xawaaraha gudbinta adiga oo yareynaya qalabka tamarta-isticmaalka, oo si weyn u yareynaya kharashyada gudbinta shabakadda.
2. Balaadhinta baaxada codsiga lana xoojiyo nidaamka macluumaadka dadweynaha
Codsiyada Qaramada Midoobay kuma koobna guryaha iyo meheradaha.Mustaqbalka, meelaha codsiyada waa la ballaarin karaa, iyo nidaamka macluumaadka bulshada waxaa loo isticmaali karaa meelaha ay ka mid yihiin dhisidda magaalo caqli badan iyo in la dhiso internetka waxyaabaha si loo hagaajiyo nidaamka macluumaadka.
3. Xoojinta amniga shabakada oo wanaaji amniga isticmaalaha
Maaddaama dambiyada internetka ay noqdaan kuwo kala duwan oo adag, amniga shabakada waa in la xoojiyaa si loo xaqiijiyo ilaalinta dhamaystiran oo dhamaystiran ee gudbinta xogta isticmaalaha.
