Wax cusubRF ka badan fiberxal
Deegaanka korantada ee maanta sii kordhaysa iyo soo ifbaxa joogtada ah ee faragelinta calaamadaha, sida loo gaaro aaminaad sare, fogaan dheer iyo gudbin xasilloon oo ishaarooyinka korantada ballaaran ayaa noqday caqabad muhiim ah oo ku saabsan cabbirka warshadaha iyo tijaabinta. RF-ka ka sarreeya fiber-ka analog-ga ah ee isku xirka transceiver indhaha waa mid cusubgudbinta fiber indhahaxal loogu talagalay in wax looga qabto caqabadan.
Qalabkani waxa uu taageeraa ururinta wakhtiga dhabta ah iyo gudbinta calaamadaha fidsan ee laga bilaabo DC ilaa 1GHz, waxaana si dabacsan loogula qabsan karaa qalabyada kala duwan ee wax lagu ogaado, oo ay ku jiraan baadhitaanada hadda jira, qalabka korontada ku shaqeeya iyo qalabka kale ee cabbiraadda heerka sare ah. Dhammaadka gudbintiisa waxaa lagu qalabeeyay 1 MΩ/50 Ω beddelka BNC interface, oo muujinaya iswaafajin ballaaran. Inta lagu jiro habaynta calaamadaha, calaamadaha korantada ayaa la beddelaa oo loo beddelaa calaamadaha indhaha, kuwaas oo lagu kala qaado dhammaadka helitaanka iyada oo loo marayo fiilooyinka indhaha ee hal-qaab ah oo si sax ah dib loogu soo celiyo calaamadaha korantada ee asalka ah moduleka helaya.
Waxaa mudan in la xuso in taxanaha R-ROFxxxxT uu isku xirayo habka xakamaynta heerka tooska ah (ALC), kaas oo si wax ku ool ah uga hortagi kara isbedbedelka calaamadaha ay keento luminta fiber-ka iyo hubinta waxqabadka joogtada ah inta lagu jiro gudbinta fogaanta fog. Intaa waxaa dheer, moduleka gudbinta waxaa lagu qalabeeyaa attenuator la qabsan karo oo la hagaajin karo, oo taageeraya saddex isbeddel oo firfircoon oo ah 1: 1 / 10: 1 / 100: 1. Tani waxay u sahlaysa isticmaalayaasha inay wanaajiyaan heerka soo dhawaynta ishaarada iyadoo lagu salaynayo xaaladaha dhabta ah oo ay balaariyaan kala duwanaanta firfircoonida nidaamka.
Si loo daboolo shuruudaha tijaabada goobta ama mobilada, taxanahan modules-yada ah waxay taageerayaan awooda batteriga iyo kontoroolka fogaanta, waxayna wataan qaab heegan ah oo caqli leh oo si toos ah u galaya xaalad awood yar inta lagu jiro xilliyada aan la isticmaalin, si wax ku ool ah u kordhiya nolosha batteriga aaladda. Tilmaamaha LED-ka ee ku yaala qaybta hore waxay bixiyaan jawaab celin-waqti-dhaq ah oo ku saabsan xaaladda hawlgalka, sii wanaajinta shaqada iyo wax-qabadka qalabka.
Haddi ay ahaan lahayd xaaladaha sida la socodka awooda, tijaabinta soo noqnoqoshada raadiyaha, ama tijaabooyin cilmi baadhiseed, taxanaha R-ROFxxxxT waxa uu siin karaa isticmaalayaasha xalal la isku halayn karo, dabacsanaan leh, oo aad uga-hortagaya faragelinta calaamada fog.
RF ka badan Fiber Sharraxaadda Alaabta
Taxanaha R-ROFxxxxTRF ka sarreeya Link fiberAnalog broadband transceiver optical link waa aalad gudbinta fog ee fiber optic si gaar ah loogu talagalay cabbiraadda waqtiga-dhabta ah ee DC ilaa 1GHz calaamadaha korantada ee jawiga korantada ee adag. Qaabka gudbinta waxa uu leeyahay 1 MΩ/50 Ω BNC, kaas oo lagu xidhi karo aaladaha kala duwan ee dareemaha (baaritaannada hadda jira, kuwa korantada sare leh ama aaladaha cabbiraadda sare ee gaarka ah). Qaybta gudbinta, calaamadda korantada gelinta ayaa la beddelaa oo loo beddelaa signalka indhaha, kaas oo markaa loo diro moduleka helaya iyada oo loo marayo fiber optic ah oo hal-hab ah. Qaabka qaataha waxa uu signalka indhaha dib ugu rogaa calaamad koronto. Gudbinta ishaarada indhaha waxaa lagu nidaamiyaa xakamaynta heerka tooska ah si loo ilaaliyo waxqabadka saxda ah ee joogtada ah, oo aan saameyn ku yeelan khasaaraha indhaha. Labada qaybood ee transceiver-ka waxay taageeraan sahayda batteriga iyo kontoroolka fogaanta. Qalabka gudbinta indhaha waxa kale oo ka mid ah attenuator la hagaajin karo (1: 1/10: 1/100: 1) si loo hagaajiyo heerka signalka la helay si loo wanaajiyo kala duwanaanshaha firfircoon. Intaa waxaa dheer, marka aaladda aan la isticmaalin, waxaa meel fog laga geli karaa habka heeganka hooseeya si loo badbaadiyo awoodda batteriga, iyo iftiinka tusaha LED wuxuu muujinayaa heerka shaqada.
