Optical fiber ndi chinthu chofunikira kwambiri pazaka zamasiku ano zama network, koma kodi mumamvetsetsadi fiber fiber? Kodi njira zolumikizirana ndi fiber ndi ziti? Kodi pali kusiyana kotani pakati pa optical cable ndi optical fiber? Kodi n'zotheka kuti CHIKWANGWANI chilowe m'malo mwa zingwe zamkuwa kuchokera kunja?
Kodi njira zolumikizirana ndi fiber ndi ziti?
1. Kulumikizana kokhazikika:
Kulumikizana mwachangu ndi njira yolumikizira tsamba kutsamba kapena tsamba ku chingwe cha fiber optic pogwiritsa ntchito zida zosiyanasiyana zolumikizirana ndi fiber optic (mapulagi ndi zitsulo). Njirayi ndi yosinthika, yosavuta, yabwino, komanso yodalirika, ndipo imagwiritsidwa ntchito nthawi zambiri pa mawaya apakompyuta m'nyumba. Attenuation yake wamba ndi 1dB / cholumikizira.
2. Kulumikizana mwadzidzidzi (kotchedwanso) kusungunuka kozizira:
Kulumikizana kwadzidzidzi makamaka kumagwiritsa ntchito njira zamakina ndi mankhwala kukonza ndi kulumikiza ulusi wamaso awiri palimodzi. Khalidwe lalikulu la njirayi ndikuti kugwirizana kuli mofulumira komanso kodalirika, ndipo kuchepetsedwa kwa kugwirizana ndi 0.1-0.3dB / mfundo.
Atha kulumikizidwa muzolumikizira ndikulumikizidwa muzitsulo za fiber optic. Cholumikizira chimagwiritsa ntchito 10% mpaka 20% ya kuwala, koma zimapangitsa kuti zikhale zosavuta kukonzanso dongosolo. nthawi yochepa.
Ikhoza kuphatikizidwa ndi makina. Kuti muchite izi, ikani mbali imodzi ya ulusi wodulidwa mosamala mu chubu ndikumangirira pamodzi. CHIKWANGWANI chikhoza kusinthidwa kudzera pamphambano kuti muwonjezere chizindikiro. Kulumikizana kwamakina kumafuna pafupifupi mphindi 5 kuti ophunzitsidwa amalize, ndipo kutayika kwa kuwala kumakhala pafupifupi 10%.
3. Kulumikizana kosatha kwa CHIKWANGWANI (kotchedwanso hot melt):
Kulumikizana kotereku kumagwiritsa ntchito kutulutsa kwamagetsi kuphatikizira ndikulumikiza malo olumikizirana ndi fiber. Nthawi zambiri amagwiritsidwa ntchito kulumikiza mtunda wautali, kulumikizana kokhazikika kapena kokhazikika kokhazikika. Mbali yake yayikulu ndikuti kulepheretsa kulumikizana ndikotsika kwambiri pakati pa njira zonse zolumikizira, zomwe zili ndi mtengo wa 0.01-0.03dB / point.
Komabe, polumikiza, zida zapadera (makina owotcherera) ndi ntchito zamaluso zimafunikira, ndipo malo olumikizira amafunika kutetezedwa ndi chidebe chapadera. Ulusi uwiriwo ukhoza kusakanizidwa pamodzi kuti ukhale wolumikizana wolimba.
Ulusi wopangidwa ndi njira yophatikizira umakhala wofanana ndi ulusi umodzi, koma pali kuchepa pang'ono. Panjira zonse zitatu zolumikizirana, pali chiwonetsero pamphambano, ndipo mphamvu yowonekera imalumikizana ndi chizindikiro.
Ndikofunikira kumvetsetsa kutayika kwa ulusi wa kuwala kuti mugwiritse ntchito bwino kuwala kwa kuwala. Ntchito yayikulu ya Fluke's CertiFiber Pro Optical Loss Test fiber loss tester ndikuyesa kutayika ndi kulephera komwe kumayambitsa ulusi.
Fluke's CertiFiber Pro Optical Loss Test fiber loss tester ikhoza:
1. Mayesero odziwikiratu amasekondi atatu - (kuwirikiza kanayi kuposa oyesa achikhalidwe) akuphatikizapo: kuyeza kwa kutaya kwa kuwala pamizere iwiri ya mafunde awiri, kuyeza mtunda ndi kuwerengera bajeti yotayika.
2. Perekani kusanthula kwachiphaso / kulephera kokha kutengera miyezo yamakampani kapena malire oyeserera
3. Dziwani njira zoyeserera zolakwika zomwe zimayambitsa "kutayika koyipa".
4.Onboard (USB) yoyendera kamera imalemba chithunzi cha fiber endface
5. Ma adapter mita yamagetsi osinthika omwe amapezeka pamitundu yonse yolumikizira (SC, ST, LC, ndi FC) panjira yolondola yodumphira imodzi
6.Built-in video error locator for basic diagnostics and polarity diagnosis
7. Kuthekera kwa kuyeza kwa mafunde awiri pamtundu umodzi kumapangitsa kuti woyesayo agwiritsidwe ntchito pamapulogalamu omwe amafunikira ulalo umodzi wokha wa ulusi.
Palibe zida zowonjezera kapena njira zomwe zimafunikira kuti zigwirizane ndi zofunikira za TIA-526-14-B ndi IEC 61280-4-1 ring flux.
Kodi pali kusiyana kotani pakati pa optical cable ndi optical fiber?
Chingwe cha kuwala chimapangidwa ndi nambala inayake ya ulusi wa kuwala. Pakatikati pa kunja ndi yokutidwa ndi sheath ndi wosanjikiza zotetezera kulankhulana ndi mtunda wautali kufalitsa uthenga waukulu mphamvu.
Optical fiber ndi chida chotumizira, ngati waya woonda wapulasitiki. Ulusi wowonda kwambiri wowoneka bwino udzakutidwa mu manja apulasitiki kuti utumize uthenga wautali. Chifukwa chake chingwe cha fiber optic chimakhala ndi ulusi wowoneka bwino.
Pomaliza, tiyeni tikambirane chingwe. Chingwe chimapangidwa ndi core conductive wire core, chosanjikiza chotsekereza, ndi chitetezo chosindikizira. Amapangidwa ndi chitsulo (makamaka mkuwa, aluminiyamu) ngati kondakitala, ndipo amagwiritsidwa ntchito popereka mphamvu kapena chidziwitso. Mawaya amapotozedwa. Zingwe zimagwiritsidwa ntchito kwambiri m'malo oyendetsa, malo ocheperako, etc. Ndipotu, mawaya ndi zingwe zilibe malire okhwima. Nthawi zambiri, timatcha mawaya okhala ndi ma diameter ang'onoang'ono ndi ma cell ochepa ngati mawaya, ndi zingwe zokhala ndi mainchesi akulu ndi ma cell ambiri.
Kodi ndi zotheka kuti ulusi wa kuwala ulowe m'malo mwa zingwe zamkuwa zakunja?
M'malo ambiri opangira ma data, CHIKWANGWANI chakhala chikulamulira msika chifukwa cha zofunikira za bandwidth. Kuphatikiza apo, zingwe za fiber optic sizimakhudzidwa ndi kusokonezedwa ndi ma elekitiroma, ndipo zofunikira pakuyika kwawo sizovuta ngati zingwe zamkuwa. Choncho, kuwala kwa fiber ndikosavuta kukhazikitsa.
Komabe, ziyenera kuzindikirika kuti ngakhale kusiyana kwa mtengo pakati pa ulusi wa kuwala ndi zingwe zamkuwa zachepa, mtengo wamtengo wapatali wa zingwe za kuwala ndi wapamwamba kuposa zingwe zamkuwa. Chifukwa chake, CHIKWANGWANI chimagwiritsidwa ntchito kwambiri m'malo omwe amafunikira ma bandwidth apamwamba, monga ma data center.
Kumbali ina, zingwe zamkuwa ndizotsika mtengo. Ulusi wagalasi ndi mtundu wapadera wa ulusi wagalasi womwe ndi wosalimba kuposa zingwe zamkuwa. Choncho, mtengo wokonza tsiku ndi tsiku wa chingwe chamkuwa ndi wotsika kwambiri kuposa wa fiber optical. Imaperekanso kuyanjana chakumbuyo ndi zida zakale za 10 / 100Mbps za Ethernet.
Chifukwa chake, zingwe zamkuwa zimagwiritsidwabe ntchito potumiza mawu komanso kugwiritsa ntchito maukonde amkati. Kuphatikiza apo, ma cabling opingasa, Power over Ethernet (POE), kapena mapulogalamu a intaneti a Zinthu akuyendetsa kugwiritsa ntchito zingwe zamkuwa. Choncho, zingwe za fiber optic sizingalowe m'malo mwa zingwe zamkuwa.
Za chidziwitso chaching'ono cha fiber optical, ndikukankhira pano kwa aliyense lero. Zingwe za fiber optic ndi zingwe zamkuwa zimatha kupereka ntchito zolumikizira intaneti m'nyumba ndi mabizinesi. M'malo mwake, mayankho a fiber ndi zamkuwa azikhala limodzi m'tsogolomu, ndipo yankho lililonse lidzagwiritsidwa ntchito pomwe lingamveke bwino.
