Kazhinji, kune mhando mbiri dzefiber: idzo dzinotsigira nzira dzakawanda dzekuparadzira kana nzira dzakachinjika dzinodaidzwa kuti multi-mode fibers (MMF), uye idzo dzinotsigira imwe modhi dzinonzi single-mode fibers (SMF). Asi chii chakasiyana pakati pavo? Kuverenga chinyorwa ichi kuchakubatsira kuwana mhinduro.
Mhedzisiro yeSingle Mode Vs Multimode Fiber Optic Cable
Single mode fiber inobvumira kupararira kwechiedza chimwe chete modhi panguva, nepo multimode optical fiber inogona kuparadzira akawanda modes. Misiyano yakakosha pakati pavo iri mu fiber core dhayamita, wavelength & mwenje sosi, bandwidth, color sheath, chinhambwe, mutengo, nezvimwe.
Single Mode Vs Multimode Fiber, Ndeupi Musiyano?
Nguva yekuenzanisa single mode vs. multimodeoptical fiberuye kunzwisisa kusiyana kwavo.
Core Diameter
Single Mode tambo ine diki musimboti saizi, kazhinji 9μm, inogonesa kuderera, mabhendi epamusoro, uye kureba kwekufambisa madaro.
Kusiyana neizvi, Multimode optical fiber ine saizi yakakura yepakati, kazhinji 62.5μm kana 50μm, ine OM1 pa62.5μm uye OM2/OM3/OM4/OM5 pa5μm. Kunyangwe paine musiyano muhukuru, hazvisi nyore kuoneka kune vakashama Eve sezvo ivo vari madiki pane upamhi hwebvudzi remunhu. Kutarisa iyo yakadhindwa kodhi pane fiber optic tambo inogona kubatsira kuziva mhando.
Iine chivharo chekudzivirira, ese ari maviri mode uye multimode fiber ane dhayamita ye125μm.
Wavelength & Chiedza Chitubu
Multimode optical fiber, nehukuru hwayo hwepakati, inoshandisa magetsi akaderera-anodhura se LEDs chiedza uye VCSELs pa850nm uye 1300nm wavelengths. Kusiyana neizvi, single mode tambo ine diki core, inoshandisa lasers kana laser diodes kugadzira mwenje wakabaiwa mutambo, kazhinji pawavelengths ye1310nm uye 1550nm.
Bandwidth
Aya marudzi maviri efiber anosiyana mukugona kwebandwidth. Single-mode fiber inopa ingangoita isina muganho bandwidth nekuda kwerutsigiro rwayo kune imwechete mwenje sosi modhi, zvichikonzera kuderera kuderera uye kupararira. Ndiyo sarudzo inosarudzika yekumhanya-mhanya kufonera madaro marefu.
Kune rimwe divi, multimode fiber inogona kufambisa akawanda optical modes, asi ine yakakwira attenuation uye yakakura kupararira, ichidzikamisa bandwidth yayo.
Single-mode fiber inodarika multimode optical fiber maererano nebandwidth simba.
Attenuation
Single-modhi faibha ine yakaderera attenuation, nepo multimode fiber iri nyore kutapudza.
Distance
Single mode tambo yekudzikira attenuation uye modhi dispersion inogonesa kureba kwekufambisa madaro pane multimode. Multimode inodhura-inoshanda asi inongogumira kune mapfupi link (eg, 550m ye1Gbps), nepo imwe chete modhi ichishandiswa kune yakarebesa-kusvika kutapurirana.
Mutengo
Kana uchifunga nezve mutengo wakazara, zvikamu zvitatu zvinoita basa rakakosha.
Installation Cost
Mari yekuisa ye single-mode fiber inowanzo onekwa seyakakwira kupfuura multimode tambo nekuda kwezvakanaka zvayo. Zvisinei, chokwadi chinopesana. nekuda kwekugadzira kwakanyatsoita, kuchengetedza 20-30% zvichienzaniswa nemultimode fiber. Kune pricier OM3/OM4/OM5 fibers, single-mode inogona kuchengetedza kusvika ku50% kana kupfuura. Nekudaro, iyo optical transceiver mutengo unofanirwa kuverengerwa.
Optical Transceiver Mutengo
Iyo optical transceiver chinhu chakakosha chinodhura chikamu mufiber cabling, inoverengera chikamu chakakura, dzimwe nguva kusvika 70% yemutengo wakazara. Single mode transceivers kazhinji inodhura 1.2 kusvika 6 nguva kupfuura multimode. Izvi zvinodaro nekuti single modhi inoshandisa yakakwirira-simba laser diodes (LD), iyo inodhura, nepo multimode michina inowanzo shandisa yakaderera-mutengo maLED kana VCSELS.
Mutengo Wekusimudzira Sistimu
Nekukurumidza kufambira mberi mune tekinoroji, macabling masisitimu anowanzoda kukwidziridzwa uye kuwedzera. Single mode fiber optic cabling inopa yakakura scalability, kuchinjika, uye kuchinjika. Multimode tambo, nekuda kweiyo shoma bandwidth uye ipfupi chinhambwe kugona, inogona kunetseka kusangana neramangwana rekuda kwekureba uye yakakwirira-vhoriyamu chiratidzo chekufambisa.
Kukwidziridza imwe mode fiber optic system yakanyanya kutwasuka, inosanganisira chete kushandura switch uye transceivers pasina chikonzero chekuisa mafibhi matsva. Kusiyana neizvi, kune multimode tambo, kukwidziridzwa kubva kuOM2 kuenda kuOM3 uyezve ku OM4 kune yakakwirira-kumhanya kutapurirana kwaizounza mutengo wakakwira zvakanyanya, kunyanya pakuchinja mafiber akaiswa pasi pevhu.
Muchidimbu, multimode inodhura-inoshanda kune mapfupi madaro, nepo imwe modhi yakanakira yepakati kusvika kureba.
Color
Coding yeruvara inorerutsa kuzivikanwa kwemhando yetambo. TlA-598C inopa iyo indasitiri kodhi yeruvara yakakurudzirwa kuti izivikanwe zviri nyore.
Multimode OM1 uye OM2 kazhinji vane jekete reorange.
OM3 inowanzova neAqua color jackets.
OM4 kazhinji ine Aqua kana Violet mavara mabhachi.
OM5 yaive neruvara rwegreen.
Single mode OS1 uye OS2 kazhinji ine Yellow jackets.
Application
Single mode tambo inonyanya kushandiswa mumashure marefu uye metro masisitimu mune telecom, datacom, uye CATV network.
Kune rimwe divi, tambo yemultimode inonyanya kuisirwa mune zvipfupi-kure maapplication senge data centers, cloud computing, kuchengetedza masisitimu, uye maLAN (Local Area Networks).
Mhedziso
Mukupedzisa, single-mode fiber cabling yakanakira kurefu-kusvika data kutapurirana mumatairi network, MANs, uye PONs. Multimode fiber cabling, kune rumwe rutivi, inonyanya kushandiswa mumabhizinesi, nzvimbo dzedata, uye maLAN nekuda kwekusvika kwayo kupfupi. Kiyi ndeyekusarudza iyo fiber mhando inonyatsoenderana netiweki yako zvinodiwa uchifunga nezve iyo yakazara fiber mutengo. Semugadziri wetiweki, kuita sarudzo iyi kwakakosha kune inoshanda uye yakavimbika network setup.
