Optical communication musimboti
Nheyo yekutaurirana ndeiyi inotevera.Pakupedzisira kwekutumira, ruzivo rwakafambiswa (senzwi) runofanira kutanga rwashandurwa kuita masaini emagetsi, uye ipapo masaini emagetsi anogadziridzwa kune laser beam inoburitswa nelaser (light source), kuti kusimba kwechiedza kunosiyana neamplitude (frequency) yezviratidzo zvemagetsi uye kuburikidza nemusimboti wekuratidzira kwese kwechiedza, chiratidzo che optical chinoparidzirwa mu optical fiber.Nekuda kwekurasikirwa uye kupararira kwefiber optical, chiratidzo che optical chichava kuderera uye kukanganiswa mushure mekutapurirwa kure. Chiratidzo chakaderedzwa chinowedzerwa pa optical repeater kugadzirisa yakakanganiswa waveform.Pakuguma kwekugamuchira, detector inogamuchira chiratidzo chemaziso uye inoshandura kuva chiratidzo chemagetsi, iyo inoderedzwa kudzorera ruzivo rwepakutanga.
Optical fiber kutapurirana zvakanakira:
● Kukurukurirana kukuru, kureba kwekutaurirana, kunzwa kwakanyanya, uye pasina kupindira kubva kune ruzha
● Ukuru huduku, uremu huremu, hupenyu hurefu, hutano hwakanaka uye mutengo wakaderera
● Insulation, high pressure resistance, high temperature, corrosion, strong adaptability
● Kuvanzika kwakanyanya
● Zvokudya zvakapfuma uye zvisingagoneki: Chinhu chinonyanya kukosha pakugadzira quartz fiber isilika, iro jecha, uye jecha ibun.
Optical fiber communication inoumbwa nenhevedzano yemidziyo yekukurukurirana yemaziso.dant in nature, saka mutengo wayo wakadzikira.Optical equipment inoiswa muzvikamu zvinoshanda uye mapassive devices.An optical active device chinhu chakakosha muoptical communication system yekushandura chinhu. chiratidzo chemagetsi kuita chiratidzo chemaziso kana kushandura chiratidzo chemaziso kuita chiratidzo chemagetsi, uye ndiwo moyo weoptical transmission system.Optical passive components midziyo inoda huwandu hwesimba mumagetsi ekutaurirana asi isina photoelectric kana electro- optic kutendeuka. Iwo makiyi node dze optical transmission masisitimu, anosanganisira fiber optic zvibatanidza, wavelength division multiplexers, optical splitters, uye optical.switches. , optical circulators uye optical isolators.
● Fiber optic patch cords (inozivikanwawo sefiber optic connectors) inoreva maplugs ekubatanidza kumativi ose etambo ye optical path active connection.Plagi kune imwe magumo inonzi pigtail.
● Wavelength division multiplexer (WDM) inobatanidza mutsara wezviratidzo zvemaziso ane marefu akasiyana-siyana uye anoatumira pamwe chete neoptical fiber imwe chete. Nzira yekukurukurirana umo zviratidzo zvemaziso zveavelengths akasiyana zvinoparadzaniswa nedzimwe nzira pamagumo ekugamuchira.
● Optical splitter (inozivikanwawo sesplitter) i-fiber-optic tandem device ine zvinyorwa zvakawanda uye zvakawanda zvinobuda. Maererano nemutemo wekuparadzanisa, optical splitter inogona kugoverwa mumhando mbiri: yakanyungudutswa taper type uye planar waveguide type ( PLC mhando).
● Opticalchinjais an optical switching device, inova chigadziro chemaziso chine imwe kana kupfuura zvingasarudzwa zvekutumira zviteshi. Basa rayo ndere panyamachinjakana zvine musoro shandisa optical masaini mumitsetse yekufambisa yemagetsi kana nzira dzakabatanidzwa dzemaziso.
● The optical circulator is a multi-port optical device ine unhu husina kudzorera.
● Kana iyo optical chiratidzo ichiiswa kubva kune chero chiteshi, inobuda kubva kune inotevera chiteshi nekurasikirwa kudiki mukurongeka kwedhijitari. Kana iyo chiratidzo ichiiswa kubva pachiteshi 1, inogona chete kubuda kubva pachiteshi 2. Saizvozvo, kana chiratidzo chikaiswa kubva pachiteshi chechipiri, chinogona chete kubuda kubva pachiteshi chetatu.
● An optical isolator mudziyo unongobvumira chiedza cheunidirectional chete kupfuura uye chinochidzivirira kuti chisapfuure chakatarisana. Nheyo yayo yekushanda yakavakirwa pakusawirirana kweFaraday kutenderera.
