Semutengesi wehunyanzvi wezvinhu zvetambo,NYIKA IMWE CHETEinopa mhando dzakasiyana-siyana dzezvinhu zvemagetsi zvetambo dzemagetsi, kusanganisira fiber yemagetsi yemhando yepamusoro ye single-mode. Senzira huru yekutumira data yemazuva ano yekutaurirana, fiber yemagetsi ye single-mode inoshandiswa zvakanyanya mumasisitimu ekutaurirana ari kure uye anomhanya zvakanyanya nekuda kwebandwidth yayo yakakwira, kuderera kwesimba, uye daro refu rekutumira data.
Muchinyorwa chino, tinoongorora hunhu hwewavelength uye kutumirwa kwe single-mode.faibha yemazisokubva pamaonero ezvinhu, zvichipa ruzivo rwakakosha pakusarudza zvinhu uye kugadzira tambo.
1. Maumbirwo Ekutanga eSingle-Mode Optical Fiber
Fiber ye optical yemhando imwe chete ine core necladding. Refractive index yecore yakakwira kupfuura yecladding, zvichiita kuti chiedza chipararire kuburikidza nekufungisisa kwemukati mukati mecore. Chimiro ichi chinotsigira nzira imwe chete yekuparadzira (fundamental mode), zvichibvisa kupararira kwemodal uye kuvandudza kunaka kwekutumira.
Dhayamita yepakati inowanzova pakati pema micrometer akati wandei kusvika pa 10 μm, nepo dhayamita yecladding iri inenge 125 μm.
2. Kukosha kweWavelength
Wavelength inoita basa rakakosha mukutaurirana kwe optical fiber. Mahwindo ekutumira magiya anoshandiswa kazhinji anosanganisira:
O-band (1260–1360 nm)
Bhendi reC (1530–1565 nm)
B-bhendi (1565–1625 nm)
Mukati meaya mawavelength, optical fibers dzinoratidza kushanda kwakanaka kwekutumira. Pakati padzo, C-band ine attenuation yakaderera (yakaderera se0.2 dB/km), zvichiita kuti ive hwindo guru rekushanda kwemasisitimu ekukurukurirana kwe optical ari kure uye anomhanya zvakanyanya.
3. Hunhu Hunokosha hweKutumira
Kuderedza Kuwanda Kwemafuta:
Kudzikira kwesimba remagetsi, kunoyerwa mu dB/km, chinhu chakakosha chinoshandiswa kuongorora kurasikirwa kwesimba remagetsi. Izvi zvinonyanya kuitika kubva mukunyudzwa kwezvinhu uye kupararira kwazvo. Mu C-band, kudzikira kwesimba remagetsi kunogona kunge kwakaderera kusvika pa 0.2 dB/km, ukuwo kwakakwira zvishoma mu O-band.
Fiber ye optical ye single-mode inopihwa neONE WORLD inogadzirwa uchishandisa zvinhu zvakachena uye maitiro akagadzikana, zvichiita kuti kushanda kwacho kurambe kwakadzikama mukati mezvinodiwa zvakajairwa zvekutumira kure kwakavimbika.
Hunhu hwekupararira:
Kupararira kunoreva musiyano wekumhanya kwechiedza pakupararira kwemafungu akasiyana, izvo zvinotungamira pakuwedzera kwechiratidzo. Nekugadzirisa kuumbwa kwezvinhu uye dhizaini yemaumbirwo, fibers dzinogona kugadzirwa dzine hunhu hwakasiyana hwekupararira kuti dzisangane nezvinodiwa zvakasiyana zvekutaurirana.
Kureba kweWavelength:
Kureba kwewavelength ndiko kureba kwewavelength uko kunokwanisa kuchengetedzwa ne single-mode transmission, kazhinji kuri pakati pe1260–1300 nm. Pasi pemutengo uyu, high-order modes dzinogona kupararira, zvichikanganisa kugadzikana kwesignali. ONE WORLD inodzora zvakanyanya wavelength ye cut-off kuti ive nechokwadi chekuti single-mode performance yakagadzikana mukati me range yakatarwa yekushanda.
Dhayamita yeMunda weModhi (MFD):
Dhayamita yemode field inotsanangura kupararira kweoptical field mufiber core uye inokanganisa kushanda zvakanaka kwecoupling uye mashandiro ekubatanidza. MFD dzakasiyana dzinowanikwa kuti dzisangane nezvinodiwa zvakasiyana-siyana zvekugadzira system uye kurongedza.
4. Kugadzirisa Kushanda Kwekutumira Mafaira
Kushanda kwe single-mode optical fiber kunogona kuvandudzwa zvakanyanya nekuvandudza kuchena kwezvinhu uye maitiro ekugadzira akadai seMCVD (Modified Chemical Vapor Deposition). Kuvandudzwa uku kunobatsira kuderedza kunyudzwa kwetsvina uye kukanganisa kwechimiro, zvichikonzera kudzikira kwesimba uye hunhu hwekupararira huri nani.
ONE WORLD inogara ichitevera budiriro yeindasitiri uye inoshanda pamwe chete nevatinoshanda navo vakavimbika kuti vape zvigadzirwa zve optical fiber zvakagadzikana uye zvemhando yepamusoro.
5. Mhedziso
Hunhu hwehurefu hwema "single-mode optical fiber" uye hunhu hwe "transmission" hwe "single-mode optical fiber" zvinosarudza zvakananga mashandiro e "optical communication systems". Kunzwisisa zvakajeka ma "parameters" aya kunobatsira kugadzirisa dhizaini ye "fiber network" uye kusangana nekudiwa kuri kukura kwe "high-speed" uye "high-capacity" ye "data transmission".
Semubatsiri akavimbika muzvinhu zvetambo, ONE WORLD yakazvipira kupa fiber yemagetsi yakagadzikana uye yakavimbika yekutsigira mapurojekiti ako ekutaurirana. Inzwa wakasununguka kutibata kuti uwane rumwe ruzivo nezvechigadzirwa uye rutsigiro rwehunyanzvi.
