Halabuurkaqalabka isgaarsiinta indhaha

Nidaamka isgaadhsiinta ee leh mowjadda iftiinka sida signalka iyo fiber-ka indhaha sida dhexdhexaadinta gudbinta waxaa loo yaqaannaa nidaamka isgaarsiinta fiber Optical. Faa'iidooyinka isgaarsiinta fiber indhaha marka la barbar dhigo isgaarsiinta cable dhaqanka iyo isgaarsiinta wireless waa: awoodda isgaarsiinta weyn, khasaaraha gudbinta hooseeyo, awoodda faragelinta anti-electromagnetic xoog leh, sir xoog leh, iyo alaabta ceeriin ee dhexdhexaad ah gudbin fiber indhaha waa Silicon dioxide kaydinta badan. Intaa waxaa dheer, fiber indhaha ayaa leh faa'iidooyinka cabbirka yar, miisaanka fudud iyo kharash yar marka la barbardhigo fiilada.
Jaantuska soo socdaa wuxuu tusinayaa qaybaha wareegga isku dhafan ee photonic ee fudud:leysarka, dib-u-isticmaalka indhaha iyo aaladaha kala-saarista,sawirqaadeiyomodulatore.

Qaab dhismeedka aasaasiga ah ee nidaamka isgaarsiinta laba jiho ee fiber indhaha waxaa ka mid ah: gudbiyaha korantada, gudbiyaha indhaha, fibre gudbinta, qaataha indhaha iyo qaataha korantada.
Digniinta korantada ee xawaaraheeda sare leh waxaa lagu dhejiyaa gudbiyaha korantada ee gudbiyaha indhaha, waxaana loo beddelaa calaamadaha indhaha ee aaladaha elektiroonigga ah sida aaladda Laser (LD), ka dibna lagu daro fiilada gudbinta.
Ka dib gudbinta fogaanta fog ee ishaarada indhaha iyada oo loo marayo fiber hal-hab ah, erbium-doped fiber amplifier ayaa loo isticmaali karaa si loo kordhiyo signalka indhaha oo uu sii wado gudbinta. Kadib dhamaadka helitaanka indhaha, ishaarka indhaha waxaa loo beddelaa calaamad koronto by PD iyo aaladaha kale, iyo signalka waxaa helaya qaataha korantada iyada oo loo marayo farsamaynta korantada ee xigta. Habka dirida iyo helitaanka calaamadaha jihada ka soo horjeeda waa isku mid.
Si loo gaaro jaangooyooyinka qalabka ee isku xirka, gudbiyaha indhaha iyo soo-dhoweeyaha indhaha ee isla goobta ayaa si tartiib tartiib ah loogu daraa Transceiver indhaha.
Xawaaraha sareModule transceiver indhahaWaxay ka kooban tahay Receiver Optical Subbassembly (ROSA; Transmitter Optical Subbassembly (TOSA) oo ay matalaan aaladaha indhaha ee firfircoon, aaladaha dadban, wareegyada shaqaynta iyo qaybaha is-dhexgalka sawir-qaadista. chips indhaha.

Marka la eego ciribtirka jireed iyo caqabadaha farsamada ee la kulma horumarinta tignoolajiyada microelectronics, dadku waxay bilaabeen inay isticmaalaan sawir-qaadayaasha xogta sidayaal si ay u gaaraan bandwidth weyn, xawaare sare, isticmaalka tamarta hoose, iyo dib u dhigista wareegga photonic inteated (PIC). Hadafka muhiimka ah ee loop isku-dhafan ee photonic waa in la xaqiijiyo is-dhexgalka shaqooyinka iftiinka iftiinka, isku-xidhka, habeynta, shaandhaynta, gudbinta, ogaanshaha iyo wixii la mid ah. Awoodda bilawga ah ee wareegyada isku dhafan ee sawir-qaadista waxay ka timaaddaa isgaadhsiinta xogta, ka dibna si weyn ayaa loogu horumariyay sawir-qaadista mikrowave, farsamaynta macluumaadka quantum, indho-indheynta aan tooska ahayn, dareemayaasha, lidar iyo meelo kale.
