Fiber pigtail imatanthawuza cholumikizira chofanana ndi chodumphira hafu chomwe chimagwiritsidwa ntchito kulumikiza ulusi wa kuwala ndi kuwala kwa fiber coupler.Zimaphatikizapo cholumikizira cha jumper ndi gawo la fiber optical.Kapena kulumikiza zida kufala ndi ODF poyimitsa, etc.
Mapeto amodzi okha a optical fiber pigtail ndi cholumikizira chosunthika.Mtundu wolumikizira ndi LC/UPC, SC/UPC, FC/UPC, ST/UPC, LC/APC, SC/APC, FC/APC.Mapeto onse a jumper ndi zolumikizira zosunthika.Pali mitundu yambiri yolumikizirana, ndipo mawonekedwe osiyanasiyana amafunikira ma couplers osiyanasiyana.Jumper imagawidwa pawiri ndipo ingagwiritsidwenso ntchito ngati pigtail.
Chigawo chapakati cha fiber multimode ndi 50-62.5μm, m'mimba mwake yakunja ya 125μm, pakati pa ulusi wamtundu umodzi ndi 8.3μm, ndipo m'mimba mwake wakunja ndi 125μm.Kutalika kwa mawonekedwe a ulusi wa kuwala kumakhala ndi kutalika kwafupipafupi 0.85μm, kutalika kwa 1.31μm ndi 1.55μm.Kutayika kwa fiber nthawi zambiri kumachepa ndi kutalika kwa kutalika kwa mafunde.Kutaya kwa 0.85μm ndi 2.5dB/km, kutayika kwa 1.31μm ndi 0.35dB/km, ndipo kutayika kwa 1.55μm ndi 0.20dB/km.Uku ndiko kutayika kochepa kwambiri kwa ulusi, ndi kutalika kwa 1.65 Kutayika pamwamba pa μm kumawonjezeka.Chifukwa cha kuyamwa kwa OHˉ, pali nsonga zotayika m'magawo a 0.90 ~ 1.30μm ndi 1.34 ~ 1.52μm, ndipo magawo awiriwa sagwiritsidwa ntchito mokwanira.Kuyambira zaka za m'ma 1980, ulusi wamtundu umodzi wakhala ukugwiritsidwa ntchito nthawi zambiri, ndipo kutalika kwa 1.31μm kwautali kwagwiritsidwa ntchito poyamba.
Multimode fiber
Multi Mode Fiber:Pakatikati pagalasi pachimake ndi chokhuthala (50 kapena 62.5μm), chomwe chimatha kufalitsa mitundu ingapo ya kuwala.Komabe, kubalalitsidwa kwapakati-mode kumakhala kwakukulu, komwe kumalepheretsa kufalikira kwa ma siginecha a digito, ndipo kumakhala kowopsa kwambiri pakuwonjezeka kwa mtunda.Mwachitsanzo: 600MB/KM kuwala kwa fiber kumangokhala 300MB bandiwifi pa 2KM.Choncho, mtunda wotumizira wa multimode fiber ndi waufupi, nthawi zambiri makilomita ochepa chabe.
Single Mode Fiber
Single Mode Fiber:Pakatikati pagalasi pachimake ndi woonda kwambiri (pakati awiri ake nthawi zambiri amakhala 9 kapena 10 μm) ndipo amatha kufalitsa mtundu umodzi wokha.Chifukwa chake, kubalalitsidwa kwake kwapakati pamachitidwe ndikochepa kwambiri, komwe kuli koyenera kulumikizana kwakutali, koma pali kubalalitsidwa kwakuthupi ndi kufalikira kwa ma waveguide.Mwanjira imeneyi, ulusi wamtundu umodzi uli ndi zofunikira zapamwamba pakukula kwa mawonekedwe ndi kukhazikika kwa gwero la kuwala, ndiko kuti, m'lifupi mwake kuyenera kukhala kocheperako komanso kokhazikika.Zabwino.Pambuyo pake, zidadziwika kuti pamtunda wa 1.31μm, kufalikira kwa zinthu ndi kufalikira kwa ma waveguide a fiber single-mode ndi zabwino ndi zoipa, ndipo kukula kwake kuli chimodzimodzi.Izi zikutanthauza kuti pamtunda wa 1.31μm, kubalalitsidwa kwathunthu kwa fiber yamtundu umodzi ndi ziro.Kuchokera pakuwona kutayika kwa mawonekedwe a kuwala kwa kuwala, 1.31μm ndiwindo lochepa lotayika la fiber optical.Mwanjira imeneyi, dera la 1.31μm wavelength lakhala zenera labwino kwambiri lothandizira kulumikizana kwa fiber optical, komanso ndilo gulu lalikulu logwirira ntchito lamakono ogwiritsira ntchito optical fiber communication system.Magawo akuluakulu a 1.31μm wamba wamtundu umodzi amatsimikiziridwa ndi International Telecommunication Union ITU-T mu malingaliro a G652, kotero fiber iyi imatchedwanso G652 fiber.
Single-mode fiber, mainchesi apakati ndi ochepa kwambiri (8-10μm), chizindikiro cha kuwala chimangoperekedwa pakona imodzi yosungunuka ndi fiber axis, ndipo imafalitsidwa munjira imodzi, yomwe imapewa kufalikira kwa modal ndikupanga chipinda chotumizira. bandwidth patali.Mphamvu yotumizira ndi yaikulu, kutayika kwa chizindikiro cha kuwala ndi kochepa, ndipo kubalalitsidwa kuli kochepa, komwe kuli koyenera kuyankhulana kwakukulu ndi mtunda wautali.
Multi-mode fiber, optical signal ndi fiber axis imafalitsidwa pamakona angapo osungunuka, ndipo kuwala kwamitundu yambiri kumafalitsidwa munjira zingapo nthawi imodzi.M'mimba mwake ndi 50-200μm, yomwe ndi yotsika poyerekeza ndi machitidwe amtundu umodzi wa fiber.Zitha kugawidwa mu multimode mwadzidzidzi CHIKWANGWANI ndi multimode graded CHIKWANGWANI.Yoyamba ili ndi pachimake chokulirapo, njira zambiri zotumizira, bandwidth yopapatiza, ndi mphamvu yaying'ono yopatsira.
RAISEFIBER imagwira ntchito bwino popanga zingwe zowoneka bwino ndi zingwe za nkhumba, ndipo imapereka zida zaukadaulo zama fiber optic kwa makasitomala okhala ndi mawaya ophatikizika.
