Sharaxaadda Badeecada
Gudbiyaha indhaha ee dibadda ee 1550nm la hagaajiyay waa badeecada ugu heerka sareeysa. Kordhi ballaca xariiqda cidhiidhiga ah (Nooca = 0.3MHz) iyo laser-ka DFB ee buuqa yar leh ee la soo dhoofiyo sida isha; Kordhi modulator-ka dibadda ee LiNbO3 ee toosan oo sare sida modulator-ka calaamadaha RF, oo leh CTB gaar ah, CSO, xakamaynta xadka SBS ee laba-jibbaaran ee soo noqnoqda, iwm. tiknoolajiyada asaasiga ah; loogu talagalay shabakadaha gudbinta masaafada dheer.
Gudbiyaha indhaha ee isbeddelka dibadda ee taxanaha 1550 waa badeecada ugu horreysa ee loogu talagalay nidaamyada gudbinta ballaaran ee shabakadaha iyo nidaamyada gudbinta indhaha ee CATV ee awoodda weyn leh. Waxaa lagu dabaqaa habaynta indhaha, gelinta indhaha, WDM, iyo casriyeynta shabakadda ee la xiriirta iyo ballaarinta nidaamka gudbinta indhaha ee 1550nm ee weyn. Waa qalabka ugu muhiimsan ee nidaamka shabakadda raadiyaha RFTV si loo xaqiijiyo nidaamyada Triple-play, FTTH, iyo 1550nm.
Muuqaalka
1. Qaabeyn badan oo loogu talagalay habaynta: Tilmaamaha si fiican loo kala soocay waxay buuxin karaan shuruudaha shabakadaha kala duwan, iyadoo leh wax soo saar hal mar ah iyo wax soo saar labanlaab ah, awoodda iftiinka ee wax soo saarkana waxaa laga dooran karaa 3dBm ilaa 10dBm.
2. Laser-ka waxqabadka sare leh: Laser-ka DFB oo leh ballaca xariiqda cidhiidhiga ah iyo buuq yar oo ah isha iftiinka iyo modulator-ka dibadda ee LiNbO3 waa modulator-ka calaamadaha dibadda.
3. Wareegga kahor-qallooca: Wareegga kahor-qallooca oo heer sare ah, oo leh waxqabadka CTB iyo CSO oo qumman marka CNR uu sarreeyo.
4. Wareegga xakamaynta SBS: Wareegga xakamaynta SBS ee sare, SBS si joogto ah ayaa loo hagaajin karaa, wuxuu ku habboonaan karaa baahiyaha shabakadda masaafada gudbinta ee kala duwan.
5. Xakamaynta AGC: Xakamaynta faa'iidada otomaatiga ah (AGC) si loo ilaaliyo wax soo saarka calaamadaha deggan marka la geliyo RF kala duwan.
6. Dammaanad koronto oo laba-geesood ah: Kaydinta laba-geesoodka ah ee ku dhex jirta, taageero koronto * kulul, badhanka otomaatiga ah.
7. Xakamaynta heerkulka otomaatiga ah oo buuxda: Xakamaynta heerkulka shasigga otomaatiga ah; taageereyaal caqli badan marka heerkulka kiisku uu gaaro 30 ℃ uu bilaabo inuu shaqeeyo.
8. Bandhig iyo digniin: Shaashadda LCD, oo leh la socodka laysarka, bandhigga dhijitaalka ah, digniinta cilladaha, maaraynta shabakadda, iyo hawlo kale; Marka xuduudaha shaqada ee laysarka ay ka leexdaan heerka la oggol yahay ee uu dejiyay software-ka, digniinta ayaa la soo jeedin doonaa.
9. Shaqada guud ee maaraynta shabakada: Is-dhexgalka RJ45 ee caadiga ah, wuxuu taageeraa SNMP, maaraynta shabakada fog ee kombiyuutarka, iyo hagaajinta AGC, SBS, OMI, iwm., ayaa sidoo kale beddeli kara qaabka iyo lambarka taxanaha ah ee lagu soo bandhigay guddiga hore, maaraynta shabakada maxalliga ah, iyo la socodka.
