1550nm gudbiyaha indhaha ee dibeda la habeeyay waa sheyga ugu sareeya. Qabo ballaca xariiqda cidhiidhiga ah (Typ.=0.3MHz) iyo sanqadh-hooseeya ee laga keenay leysarka DFB sida isha; U yeelo LiNbO3 modulator dibadeed toosan oo ah modulator signal RF, oo leh CTB gaar ah, CSO, laba-soo noqnoqoshada sare ee SBS xakamaynta, iwm. tignoolajiyada asaasiga ah; loogu talagalay shabakadaha gudbinta fogaanta.
Taxanaha 1550-ka ah ee wax-ka-beddelka dibadda ah ee gudbinta indhaha ayaa ah xulashada koowaad ee badeecada isku xirka nidaamyada gudbinta ballaaran iyo nidaamyada gudbinta indhaha ee CATV ee awoodda ballaaran. Waxaa lagu dabaqaa habaynta indhaha, gelinta indhaha, WDM, iyo hagaajinta shabakadaha la xidhiidha iyo ballaarinta nidaamka gudbinta indhaha ee weyn ee 1550nm. Waa qalabka xudunta u ah nidaamka shabakadda raadiyaha RFTV si loo xaqiijiyo hababka Triple-play, FTTH, iyo 1550nm.
Muuqaal
1. Isku-habeyn badan oo loogu talagalay habeynta: Tilmaamaha si fiican loo kala soocay ayaa buuxin kara shuruudaha shabakadaha kala duwan, oo leh hal wax soo saar iyo laba jeer, iyo soo saarista awoodda indhaha ayaa laga dooran karaa 3dBm ilaa 10dBm.
2. Laysarka waxqabadka sare leh: laser DFB oo leh ballac xariiq cidhiidhi ah iyo sanqadh hooseeya sida isha iftiinka iyo modulatorka dibadda ee LiNbO3 waa modulator-ka dibadda.
3. Wareegga qalloocinta ka hor: Wareegga qalloocan ee ka horreeya, oo leh waxqabadka CTB iyo CSO qumman marka CNR uu sarreeyo.
4. Wareegga xakamaynta SBS: Wareegga xakamaynta SBS ee sare, SBS si joogto ah loo hagaajin karo, waxay ku haboonaan kartaa dalabaadka shabakadaha fogaanta gudbinta ee kala duwan.
5. Xakamaynta AGC: Xakamaynta helitaanka otomaatiga ah (AGC) si loo ilaaliyo soosaarka calaamadda xasilloon marka la soo galiyo RF kala duwan.
6. Damaanad qaadka korontadu laba-geesoodka ah: Ku-dhisnaanta korantada laba-geesoodka ah, taageer kulul * plug-ka, beddelka tooska ah.
7. Xakamaynta heerkulka tooska ah ee tooska ah: Xakamaynta heerkulka auto chassis; taageerayaasha caqliga leh marka heerkulka kiisku ilaa 30 ℃ bilaabo inuu ordo.
8. Muujinta iyo qaylo-dhaanta: Muujinta LCD, oo leh kormeerka laser, bandhig dijital ah, digniin qalad ah, maareynta shabakada, iyo hawlo kale; Marka cabbirada shaqada ee laysarka ay ka leexdaan xadka la oggol yahay ee software-ku dhigay, alaarmiga waa la soo dayici doonaa.
9. Guud ahaan shaqada maamulka shabakada: Isku xirka caadiga ah ee RJ45, wuxuu taageeraa SNMP, maamulka shabakada fog ee kombiyuutarka, iyo hagaajinta AGC, SBS, OMI, iwm. maamulka shabakada, iyo la socodka.
