Optical fiber inotamisa masaini muchimiro chechiedza pulses, uye inoshandisa girazi kana plexiglass senzira yekufambisa network.Iyo ine fiber core, cladding uye inodzivirira chivharo.Optical fiber inogona kukamurwa kuita Single Mode fiber uye Multiple Mode fiber.
Single-mode optical fiber inongopa nzira imwe chete yekuona, iyo yakaoma kugadzirisa, asi ine hukuru hwekutaurirana uye kureba kwekufambisa kureba.Multimode fiber inoshandisa nzira dzakawanda dze optical kuendesa chiratidzo chimwe chete, uye kumhanya kwekufambisa kunodzorwa nekudzorwa kwechiedza.
Optical fiber inowanzo shandiswa pakufambisa kwema network network.Munguva yekutapurirana, mhando dzakasiyana dze optical fibers dzinosarudzwa zvinoenderana nenharaunda uye kutapurirana zvinodiwa.Kune marudzi anotevera emafiber optical anoshandiswa mumakombuta network
A. 8.3pm core/125pm shell, single-mode Optical cable;
B. 62.5um core/125um shell, multimode optical cable;
C. 5OPm core/125pm shell, multimode optical cable;
D. Loopm musimboti/140pm goko, multimode optical tambo.
Iyo tambo yemaziso inonyanya kuumbwa neoptical fibers (bvudzi regirazi rakatetepa sebvudzi) uye epurasitiki ekudzivirira maoko uye epurasitiki sheaths.Iko hakuna simbi yakaita segoridhe, sirivheri, mhangura uye aluminium muOptical cable, uye kazhinji hapana kukosha kwekudzokorora.An optical cable inzira yekutaurirana umo imwe nhamba ye optical fibers inoumba tambo yetambo mune imwe nzira, iyo yakafukidzwa nesheath uye imwe yakafukidzwa nekunze sheath kuti ione kutapurirana kwezviratidzo zvemaziso.Kureva: tambo inoumbwa neoptical fiber (optical transmission carrier) mushure meimwe nzira.Chimiro cheiyo optical tambo inowanzo umbwa netambo core, yakasimbiswa simbi waya, yekuzadza, uye sheath.Pamusoro pezvo, kune zvimwe zvinhu zvakaita sechitubu chisingapindi mvura, buffer layer, uye insulated simbi waya sezvinodiwa.
Chikonzero chikuru chekukurumidza kukura kwefiber optic cable ndechekuti ine zvinotevera maitiro:
1. Iyo yekufambisa bandwidth yakakura kwazvo uye kugona kutaurirana kwakakura kwazvo;
2. Kurasikirwa kwekutapurika kwakaderera uye kureba kwerelay kure, kunyanya yakakodzera kutenderera kure-kure;
3. Simba rinopesana nemheni uye anti-electromagnetic interference capabilities;
4. Kuvanzika kwakanaka, kusiri nyore kuvanzwa kana kubvunzurudzwa data;
5. Ukuru hudiki uye uremu huremu;
6. Low bit kukanganisa mwero uye yakakwirira kutapurirana kuvimbika;
7. Mutengo uri kudonha nguva dzose.
Chimiro cheiyo optical tambo inowanzo umbwa netambo core, yakasimbiswa simbi waya, yekuzadza, uye sheath.Pamusoro pezvo, kune zvimwe zvinhu zvakaita sechitubu chisingapindi mvura, buffer layer, uye insulated simbi waya sezvinodiwa.Iyo optical tambo inoumbwa neyakasimbiswa core uye cable core, sheath uye kunze sheath.Kune mhando mbiri dzetambo core structure: single-core type uye multi-core type: single-core type ine marudzi maviri: full type uye tube bundle type;multi-core type ine marudzi maviri: ribhoni uye unit unit.Iyo yekunze sheath ine marudzi maviri esimbi yesimbi uye isiri-yombo.
Iyo yekugadzira maitiro eiyo optical tambo inowanzo kupatsanurwa mune anotevera maitiro:
1. Kuongororwa kwefiber optical: sarudza iyo optical fiber ine yakanakisa kutapurirana maitiro uye inokwanisa tension.
2. Staining of optical fiber: Shandisa mwero wakazara chromatogram kumaka, zvinoda kusapera uye kutama pane tembiricha.
3. Secondary extrusion: shandisa plastiki ine yakakwira elastic modulus uye yakaderera linear yekuwedzera coefficient kuti iwedzere muchubhu yeimwe saizi, isa faibha mujeli-inodzivirira uye isingapinde mvura, uye uichengete kwemazuva mashoma (kwete isingasviki maviri. mazuva).
4. Twisted optical cable: twist akawanda extruded optical fibers neyakasimbiswa unit.
5. Svetesa sheath yekunze kwetambo ye optical: wedzera jira re sheath kune yakamonyoroka optical cable.
