Ubwino wa chingwe cha fiber ndi momwe mungasankhire chingwe cha fiber

Pazaka zingapo zapitazi, chingwe cha fiber optic chakhala chotsika mtengo.Tsopano imagwiritsidwa ntchito pazinthu zambiri zomwe zimafuna chitetezo chokwanira ku kusokonezedwa ndi magetsi.Fiber ndi yabwino pamakina apamwamba kwambiri a data monga FDDI, multimedia, ATM, kapena netiweki ina iliyonse yomwe imafuna kusamutsa mafayilo akulu, owononga nthawi.

Ubwino wina wa fiber optic chingwe pamwamba pa mkuwa ndi:

• Mtunda waukulu-Mutha kuthamanga ulusi mpaka makilomita angapo.• Kutsika pang'ono-Maziko a kuwala amakumana ndi kukana pang'ono, kotero deta ikhoza kuyenda kutali.

• Chitetezo-Mapampu mu chingwe cha fiber optic ndizosavuta kuzizindikira.Chingwecho chikaponyedwa, chimatulutsa kuwala, zomwe zimapangitsa kuti dongosolo lonse lilephereke.

• Bandiwifi yayikulu-Fiber imatha kunyamula zambiri kuposa mkuwa.• Chitetezo cha mthupi-Fiber optics sichimasokoneza.

Single-mode kapena multimode?

Ulusi wamtundu umodzi umakupatsani mwayi wotumizira kwambiri komanso mtunda wofikira nthawi 50 kuposa ma multimode, komanso amawononga ndalama zambiri.Ulusi wamtundu umodzi uli ndi phata laling'ono kwambiri kuposa ma multimode fiber-nthawi zambiri ma microns 5 mpaka 10.Ndi magetsi amodzi okha omwe amatha kufalitsidwa panthawi yake.Kachingwe kakang'ono kakang'ono ndi kuwala kamodzi kokha kumachotsa kupotoza kulikonse komwe kungabwere chifukwa cha kuwala kodutsana, kumapereka chidziwitso chochepa kwambiri komanso kuthamanga kwapamwamba kwambiri kwa mtundu uliwonse wa chingwe cha fiber.

Multimode fiber imakupatsirani bandwidth yayikulu pa liwiro lalitali mtunda wautali.Mafunde amagetsi amamwazikana m'njira zingapo, kapena njira zambiri, akamayenda pakati pa chingwecho.Ma diameter amtundu wa multimode fiber core diameters ndi 50, 62.5, ndi 100 micrometer.Komabe, pazingwe zazitali (zoposa 3000 mapazi [914.4 ml), njira zingapo za kuwala zingayambitse kusokoneza kwa chizindikiro pamapeto olandira, zomwe zimapangitsa kuti deta isamveke bwino komanso yosakwanira.

Kuyesa ndi kutsimikizira chingwe cha fiber optic.

Ngati mumazolowera kutsimikizira chingwe cha Gulu 5, mudzadabwitsidwa kuti ndizosavuta kutsimikizira chingwe cha fiber optic chifukwa ngati sichingasokonezedwe ndi magetsi.Muyenera kungoyang'ana miyeso yochepa:

• Kuchepetsa (kapena kutayika kwa decibel) -Kuyesedwa mu dB / km, uku ndiko kuchepa kwa mphamvu ya chizindikiro pamene ikuyenda kudzera mu chingwe cha fiber optic.• Kubwerera kutayika-Kuchuluka kwa kuwala kumawonekera kuchokera kumapeto kwa chingwe kubwerera ku gwero.Kutsika kwa chiwerengerocho, kumakhala bwinoko.Mwachitsanzo, kuwerenga kwa -60 dB kuli bwino kuposa -20 dB.

• Grade refractive index-Imayezera kuchuluka kwa kuwala komwe kumatumizidwa pansi pa ulusi.Izi nthawi zambiri zimayesedwa pamafunde a 850 ndi 1300 nanometers.Poyerekeza ndi ma frequency ena ogwiritsira ntchito, magawo awiriwa amatulutsa mphamvu yotsika kwambiri.(Dziwani izi ndizovomerezeka pa fiber multimode zokha.)

• Kuchedwa kufalitsa-Iyi ndi nthawi yomwe imatengera chizindikiro kuyenda kuchokera kumalo ena kupita kumalo ena kudzera pa njira yopatsirana.

• Time-domain reflectometry (TDR) -Imatumiza ma pulse apamwamba kwambiri pa chingwe kuti muthe kuyang'ana zowonetsera pamodzi ndi chingwe ndikudzipatula zolakwika.

Pali zoyesa zambiri za fiber optic pamsika lero.Ma Basic fiber optic testers amagwira ntchito powunikira mbali imodzi ya chingwe.Kumapeto ena, pali wolandila wolumikizidwa ku mphamvu ya gwero la kuwala.Ndi mayesowa, mutha kuyeza kuchuluka kwa kuwala komwe kumapita mbali ina ya chingwe.Nthawi zambiri, oyesa awa amakupatsirani zotsatira za decibel (dB) zotayika, zomwe mumaziyerekeza ndi bajeti yotayika.Ngati kutaya kwake kuli kochepa kuposa chiwerengero chowerengedwa ndi bajeti yanu yotayika, kuyika kwanu kuli bwino.

Oyesa atsopano a fiber optic ali ndi kuthekera kosiyanasiyana.Atha kuyesa ma siginecha onse a 850- ndi 1300-nm nthawi imodzi ndipo amathanso kuyang'ana Gable yanu kuti ikutsatira miyezo yeniyeni.

Nthawi yosankha fiber optic.

Ngakhale chingwe cha fiber optic chikadali chokwera mtengo kwambiri kuposa mitundu ina ya zingwe, chimakondedwa ndi mauthenga amakono othamanga kwambiri chifukwa chimathetsa mavuto a chingwe chopotoka, monga pafupi-end crosstalk (NEXT), electromagnetic interference (EIVII), ndi kuphwanya chitetezo.Ngati mukufuna chingwe cha fiber mungathe kuyenderawww.mireko-cable.com.
