A fiber optic cable is network cable iyo inoshandisa michina yegirazi fiber mukati mekuchengetedzwa kwepakisi. Iyo yakagadzirirwa kure kure, iyo yakakwirira-kushandiswa kwekubatanidza data, uye kuterevhizheni.
Inofananidzwa nemataipi akaoma, fiber optic cables inopa hupamhi hwepamusoro uye inogona kutumira dharairi pamharaunda yakareba.
Fiber optic cables inotsigira zvakawanda zvekambani yenyika, terevhizheni terevhizheni uye nhare dzefoni.
Nzira dze Fiber Optic Cables Dzinoshanda
Fiber optic cables inotakura magwaro ekukurukurirana achishandisa kupisa kwechiedza chinobudiswa nevana mashoma lasers kana chiedza-emitting diodes (LEDs).
Iyo kambani inosanganisira imwe kana zvigadzirwa zvegirazi, rimwe nerimwe rinopfuvura zvishoma kupfuura bvudzi revanhu. Pakati pepande imwe neimwe inonzi inheyo, inopa nzira yekuedza kufamba. Nheyo yakakomberedzwa neganda regirazi rainzi cladding rinoratidza chiedza mukati kuti urege kurasikirwa kwechiratidzo uye kubvumira chiedza kuti chipfuure kuburikidza mumakumbo.
Iyo miviri miviri yakakura ye fiber cables inonzi sarudzo imwe chete uye multi-mode fiber. Single mode fiber inoshandisa micheka yakaoma yegirazi uye laser kuti iite chiedza apo ma-multi-mode fibers anoshandisa LED.
Single mode fiber network dzinoshandisa nzira dzeWave Division Multiplexing (WDM) nzira dzokuwedzera huwandu hwemashoko emigwagwa anokwanisa kutumirwa kudarika tambo. WDM inobvumira chiedza pane zvakasiyana-siyana zvevevelengths kuti zvibatanidzwe (multiplexed) uye gare gare zvakaparadzaniswa (de-multiplexed), zvichibudirira kutumira mitsara yakawanda yekukurukurirana kuburikidza nechimwe chiedza chekupisa.
Makomborero eFiber Actic Cables
Fiber cables dzinopa huwandu hwezvakanaka pamusoro pemaitiro akareba-kure nematare copper cabling.
- Fiber optics ine simba rakakwirira. Nhamba yehutano bandwidth fiber cable inogona kutakura nyore nyore kupfuura iyo yemhangura yemhangura yakafanana. Fiber cables yakarongwa pa 10 Gbps, 40 Gbps uye kunyange 100 Gbps yakaenzana.
- Sezvo chiedza chichifamba marefu marefu marefu pasi fiber chipfeko pasina kurasikirwa nesimba rayo, inoderedza kudiwa kwemashoko ekusimudzira.
- Fiber haigoni kupindira. A mutambo netambo tsvina inoda kushandiswa kudzivirira kuchengetedza kwayo kubva pakuvhiringidzwa kwemagetsi. Kunyange zvazvo ichi chivharo chichibatsira, hazvina kukwana kudzivirira kupindira apo tambo dzakawanda dzakabatana pamwe chete pedyo. Zvisikwa zvegirazi uye fiber cables dzivisa zvakawanda zvezviitiko izvi.
Fiber To Home (FTTH), Zvimwe Zvinoshandiswa, uye Fiber Networks
Kunyange zvazvo fiber yakawanda yakagadzirirwa kutsigira kure kurema kwekubatana pakati pemaguta nenyika, vamwe vashandi vekugara zvekutsvaga vakaisa mari yekuwedzera fiber yavo yekugadzirisa maguta edzimba dzepamhenderekedzo dzemuganhu kuti zviwane nyore kupinda mhuri. Vapei uye vashandi vezvimbambani vanoshevedza iyi "mairi ekupedzisira" kuiswa.
Mamwe mapurogiramu anozivikanwa neFTTH mumusika nhasi anosanganisira Verizon FIOS neGoogle Fiber. Aya mazano anogona kupa gigabit (1 Gbps) internet inowedzera kumhuri imwe neimwe. Zvisinei, kunyange zvazvo vapeji vanopawo mari shoma, vanowanzopawo mapuraneti emadzikiti akaderera kune vatengi vavo.
- FTTP (Fiber to the Premises): Fiber yakaiswa nenzira yose kusvika kuchivako.
- FTTB (Fiber to Building / Business / Block): Izvo zvakafanana neFTTP.
- FTTC / N (Fiber to Curb of Node): Fiber yakagadzirirwa node asi asi mhepo dzemhangura dzinozadza ukama mukati meimba.
- Tarisa fiber: Fiber inobva muhofisi yepamusoro uye inowanikwa kune mumwe mutengi. Izvi zvinopa huwandu hwemagetsi asi hunodhura.
- Yakagadziriswa fiber: Inofanana nekuendesa fiber kunze kwekuti sezvo fiber inoswedera pedo neimba yevanoshambadzirana vari pedyo, inoparadzaniswa kuva dzimwe fiber kune avo vanoshandisa.
Chinonzi Dark Fiber?
Izwi rokuti dark fiber (rinowanzosvibiswa rima fiber kana kuti inonzi flit unlit ) inowanzoreva kune yakaiswa fiber optic cabling iyo isiri kushandiswa iye zvino. Iko dzimwe nguva inoreva zvakare kumagadzirirwo akachengeterwa fiber ari oga.
