Boka re vanoongorora paTsinghua University (Chinese) ane akagadzira nzira yekuteerera nhaurirano mumba ine optical cable, semuenzaniso, inoshandiswa kubatanidza kuInternet.
Kudengenyeka kwenzwi kunogadzira kudonha kwemhepo mumhepo, saka ma microvibrations anogadzirwa muoptical tambo, yakagadziridzwa nemwenje wave inofambiswa kuburikidza netambo. Izvo zvinokonzeresa kukanganisa zvinogona kuongororwa pamusoro pechinhambwe chakakura zvakakwana uchishandisa Mach-Zehnder laser interferometer.
Mumakore achangopfuura, fiber optic network yakapararira pasi rose, iyo isingafambisi chete kuendesa data, asi inopawo mukana wekuwana mamwe mashoko.
Aya maapplication efiber optic network, kusanganisira kuona kudengenyeka, traffic yemudhorobha kuyerera kwekutarisa [7-10], kuongororwa kwepasi pevhu geological zvimiro, nezvimwewo, vane mhedzisiro yakanaka pakugadzirwa uye hupenyu hwevanhu. Zvisinei, zvinounzawo zvimwe zvinokwanisa nyaya dzekuchengetedza, dzinofanirwa kunyatsotariswa.
Panguva yekuedza, zvaive zvichikwanisika kuziva zvizere inzwi yekutaura pamberi pechidimbu chakavhurika chetambo yemaziso (FTTH) mamita matatu pamberi pemodemu.
Chiyero chacho chakaitwa kure nemakiromita 1,1 kubva kumagumo etambo iri muimba yekuteerera. Kuteerera kwakasiyana uye kukwanisa kusefa kunze kwekupindira kunopindirana nehurefu hwetambo muimba, kureva kuti, sezvo kureba kwetambo muimba inoderera, kureba kwaunogona kuteerera kunodererawo.
Zvinotaridzwa kuti kuona uye kudzoreredzwa kwechiratidzo cheodhiyo mune optical communication network inogona kushandiswa pachivande, isingaonekwi kumuteereri uye pasina kutyora mabasa ekutaura anoshandiswa. Kutsvedza zvine hungwaru muchiteshi chekutaurirana, vatsvakurudzi vakashandisa division multiplexer yewavelength (WDM, Wavelength Division Multiplexer). Kuwedzera kuderedzwa kweyero yeruzha kumashure kunowanikwa nekudzikamisa maoko e interferometer.
Optical fibers inonzwa kune kusiyana kwe ambient pressure, iyo inogona kukonzerwa
neacoustic waves. Midziyo yakavakirwa pachinhu ichi inoshandiswa zvakanyanya pakuona ruzha, senge fiber optic mahydrophone. Zvichienderana neyazvino fiber-ku-the-imba (FTTH) deployment mode, tail fiber inosvika kumamita akati wandei ichaiswa mudzimba dzevagari. Pamafambo emukati aya, masaini eruzha aikwanisa kuchinjwa pamasaisai echiedza anofambiswa imomo, zvichiita kuti vamwe vateerere voatora kunzvimbo dziri kure pedyo nefiber link.
Zvichakadaro, iyo yekutanga yekutaurirana basa refiber haizokanganiswi nekushandiswa kwewavelength division multiplexer (WDM). Naizvozvo, kuteerera kunogona kuitwa muchivande. Muchikamu chino, isu tinokurudzira espionage scheme tichishandisa indoor fiber optics uye
zviratidze murabhoritari. Iyo sisitimu yakavakirwa paMach-Zehnder heterodyne
interferometer. Isu takabatanidza hurongwa hwekuteerera kune 1,1 kilometer fiber optic link
kure nechinangwa chekuteerera, manzwi ekutaura kwevanhu kwakajairika (50 ~ 80 dB) anogona kuva
yakavharwa ne 3 metres indoor muswe fiber. Ruzha rweSistimu uye kugona kwekuteerera kunoongororwa. Pakupedzisira, tinokurukura matanho ekudzivirira njodzi yekuvanzwa zvisiri pamutemo.
countermeasures kuterera pachivande sanganisira kuderedza kureba kwetambo ye optical mumba uye woisa tambo mumatanho akaomarara. Iwe unogona zvakare kushandisa APC Optical connectors (Angled Physical Connection) yakatenderedzwa pachinzvimbo che flat end connector (PC) kuderedza kunzwa kwakanaka. Kune vanogadzira tambo dzefiber optic, zvinokurudzirwa kushandisa zvinhu zvine yakakwira modulus yekunyungudika, sesimbi negirazi, sefiber cladding.
Chekupedzisira, kune avo vanoda kuziva zvakawanda nezvazvo, vanogona kubvunza ruzivo rweongororo Mune inotevera chinongedzo.
