Hordhac Kooban
1550nm Fiber Optical Fiber Amplifier-ka awoodda sare leh wuxuu qaataa laba-marxalad-weyneyn, marxaladda koowaad waxay qabataa EDFA-gaaban, heerka labaadna wuxuu qaadanayaa awoodda sare ee EYDFA. Wadarta awoodda wax soo saarka indhaha waxay gaari kartaa 41dBm. Waxay bedeli kartaa dhowr ama daraasiin EDFAs ah, taas oo si weyn u dhimi karta kharashka dhismaha iyo dayactirka shabakada, oo yareyn karta booska hore ee hore. Deked kasta oo wax soo saar ahi waxay gundhigtaa CWDM, isku dhufashada calaamadaha CATV iyo socodka xogta OLT PON. Qalabku wuxuu ka ciyaari doonaa door muhiim ah oo sii kordheysa ee fidinta joogtada ah iyo ballaarinta shabakadda fiber optic. Waxay siisaa xal aad u deggan oo qiimo jaban oo loogu talagalay FTTH ciyaar saddex jibaaran iyo caymis ballaaran.
Labada ikhtiyaari ikhtiyaari ah ee fiber indhaha ah ayaa dhab ahaantii isku daraya nidaamka beddelka indhaha oo dhammaystiran, kaas oo loo isticmaali karo kaydka waddooyinka indhaha A iyo B. Marka dariiqa indhaha ee ugu weyni uu ku guuldareysto ama hoos u dhaco heerka, qalabku wuxuu si toos ah u beddeli doonaa khadka keydka ah ee indhaha. si loo hubiyo hawlgalka joogtada ah ee aaladda. Alaabtan waxaa inta badan loo adeegsadaa shabakadda giraanta fiber optic ama shabakad kayd ah oo aan badnayn. Waxay ka kooban tahay waqtiyo beddelasho gaagaaban (<8 ms), khasaare hoose (<0.8 dBm), iyo beddelka gacanta ee qasabka ah.
Ka tagista habka hawlgalka nooca badhanka, waxa ay ku qalabaysan tahay shaashad LCD ah oo taabasho aad u dhammaystiran iyo interface interface gaar ah oo caqli leh. Sawirrada, astaanta, iyo qaabaynta waa sahlan tahay in la fahmo, taas oo u oggolaanaysa isticmaalayaasha inay si fudud oo habboon u shaqeeyaan. . Qalab aan lahayn buug-gacmeed.
Qaybaha ugu muhiimsan waa laser bamka sumadda sare iyo fiilooyinka indhaha ee firfircoon ee laba-laaban. Naqshadeynta dariiqa indhaha ee la wanaajiyey iyo habka wax soo saarka ayaa hubiya waxqabadka ugu wanaagsan ee indhaha. APC si elektaroonik ah loo xakameeyo (Automatic Power Control), ACC (Automatic Current Control) iyo ATC (Automatic Temperature Control) waxay xaqiijiyaan xasiloonida sare iyo isku halaynta awooda wax soo saarka, iyo sidoo kale waxqabadka indhaha ee aad u fiican.
Nidaamku wuxuu isticmaalaa MPU (microprocessor) oo leh xasilooni sare iyo saxnaan sare. Naqshadeynta qaab dhismeedka kulaylka ee la hagaajiyay iyo hawo wanaagsan iyo naqshadaynta kuleylka ayaa hubiya nolosha dheer iyo kalsoonida sare ee qalabka. Iyada oo ku saleysan shaqada maamulka shabakadda ee awoodda leh ee nidaamka TCP/IP, kormeerka shabakadda iyo maaraynta madaxa-dhamaadka ee heerka aaladda qanjidhada badan waxaa lagu fulin karaa iyada oo loo marayo is-dhexgalka maaraynta shabakadda RJ45, waxayna taageertaa qaabaynta sahayda korantada oo badan, taas oo waxay hagaajisaa ku-dhaqanka iyo wax-ku-oolnimada. Kalsoonida qalabka.
Astaamaha
1. Qaadashada nidaamka qalliinka shaashadda taabashada buuxda, waxay soo bandhigi kartaa waxyaabo qani ah oo ay ku jiraan index kasta si faahfaahsan oo dareen leh si ay u caddahay jaleecada, hawlgal fudud, waxaad aragto waa waxaad heleyso, isticmaalayaashu waxay u shaqeyn karaan aaladda si fudud, iyo ku habboon la'aanteed buug-gacmeedka.
2. Badhan dayactirka oo si degdeg ah hoos ugu dhacaya 6dB ayaa lagu daraa liiska ugu muhiimsan. Shaqadani waxay si degdeg ah u yareyn kartaa 6dBm deked kasta (≤18dBm soo saarista), waxayna ka fogaan kartaa xudunta fiber-ka ee balastarka in la gubo marka la xidho oo laga baxo l. Dayactirka ka dib, waxay si dhakhso ah ugu soo celin kartaa xaaladdeeda shaqo ee asalka ah.
3. Waxay qabataa laysarka bamka ee sumadda sare iyo labajibbaaran fiber firfircoon.
4. Deked kasta oo wax soo saar leh waxaa lagu dhisay CWDM.
5. La jaanqaadi kara FTTx PON kasta: EPON, GPON, 10GPON.
6. Fiican APC, ACC, ATC, iyo AGC naqshadeynta wareegga indhaha waxay hubisaa qaylada hoose, wax soo saarka sare, iyo kalsoonida sare ee qalabka ee dhammaan band hawlgalka (1545 ~ 1565nm). Isticmaalayaashu waxay u bedeli karaan APC, ACC, iyo AGC hawlaha sida ay u kala duwan yihiin baahiyahooda dhabta ah.
7. Waxay leedahay shaqada ilaalinta otomaatiga ah ee wax-soo-gelinta hoose ama wax-soo-saarka. Marka awoodda wax gelinta indhaha ay ka hooseyso qiimaha la dejiyay, laysarka si toos ah ayuu u xirmi doonaa si uu u ilaaliyo badbaadada qalabka.
8. Wax soo saarka la hagaajin karo, kala duwanaanta hagaajinta: 0 ~ -4dBm.
9. Tijaabada RF ee qaybta hore (ikhtiyaar).
10. Wakhtiga beddelka qalabka indhaha oo gaaban, khasaaruhuna waa yar yahay. Waxay leedahay shaqooyinka beddelka tooska ah iyo beddelidda gacanta ee qasabka ah.
11. Ku-dhismay sahay koronto oo labajibbaaran, si toos ah u shidmay oo kulaylaha la taageeray.
12. Halbeegyada hawlgalka ee mashiinka oo dhan waxaa gacanta ku haya microprocessor, iyo muujinta heerka LCD ee qaybta hore waxay leedahay hawlo badan sida kormeerka heerka laser, bandhigga cabbirka, alaarmiga qaladka, maareynta shabakada, iwm.; mar marka cabirrada hawlgalka ee leysku ka leexdaan xadka la ogol yahay ee uu dhigay
13. Isku xirka caadiga ah ee RJ45 ayaa la bixiyaa, isagoo taageeraya SNMP iyo WEB maamulka shabakada fog.
