PVC, kapena polyvinyl chloride, ndi pulasitiki yomwe imagwiritsidwa ntchito kwambiri—kuyambira mapaipi mpaka zovala. Yopangidwa kuchokera ku vinyl chloride, PVC imadziwika chifukwa cha kulimba kwake, kulemera kwake kochepa komanso mtengo wake wotsika. Amaigwiritsa ntchito pansi pa nyumba, mafelemu a zenera komanso ngakhale makadi a ngongole. Siichita dzimbiri, kotero imakhala nthawi yayitali m'malo onyowa. PVC imatha kupangidwa kukhala yofewa kapena yolimba zomwe zimapangitsa kuti ikhale ndi ntchito zambiri padziko lonse lapansi. Opanga ena amawonjezera zinthu zina kuti asinthe kufewa kwake kapena kuuma kwake. Chifukwa cha kusinthasintha kwake, PVC yasintha momwe timamangira, kupanga, komanso kuteteza. Nkhani yotsatirayi ikufotokoza momwe polyvinyl chloride imapangidwira komanso komwe imaonekera m'moyo watsiku ndi tsiku.

Fiber optic ndi chingwe chomwe chimatumiza deta ngati kuwala pamwamba pa galasi kapena ulusi wa pulasitiki. Chimayendetsa zizindikiro mwachangu kwambiri komanso pamtunda wautali kuposa mizere yakale yamkuwa. Ma ISP angapo akupereka kale fiber optic kuti azithamanga mwachangu komanso modalirika kunyumba ndi kuntchito. Zingwezo ndi zoonda koma zolimba, nthawi zina sizili zazikulu kuposa tsitsi. Sizimasokonezedwa ndi zingwe zamagetsi kapena nyengo, kotero zimakhala zokhazikika pafupifupi kulikonse. Fiber optic tsopano ili muzinthu zambiri, monga makanema owonera, mafoni apakanema, ndi malo osungira mitambo. Kuti tifotokoze momwe fiber optic imagwirira ntchito komanso chifukwa chake ndiyofunikira, magawo otsatirawa akufotokoza zoyambira ndi ntchito zothandiza.

Kumanga zitsulo ndi chingwe cholimba kwambiri, chathyathyathya chomwe chimagwiritsidwa ntchito pomanga zinthu zolemera kuti zisungidwe kapena kutumizidwa. Kaya m'nyumba zosungiramo katundu, mafakitale, kapena m'masitolo ang'onoang'ono, kumanga zitsulo kumasunga katundu wotetezeka komanso wokhazikika pamene akuyenda. Ntchito yake yayikulu ndikumanga zinthu zolemera, monga matabwa, mapaipi, kapena zida zamakanika, kukhala phukusi loyera komanso lopapatiza. Ndi mphamvu yolimba komanso nthawi yayitali, kumanga zitsulo ndikwabwino kwambiri pantchito zomwe zingwe zapulasitiki kapena nsalu sizikugwira ntchito. Antchito ambiri amasankha kumanga zitsulo pamapulojekiti omwe amafunikira chisamaliro chochulukirapo, monga kutumiza zinthu kunja kwa dziko kapena kunyamula katundu wakuthwa. Kudziwa nthawi komanso chifukwa chake kugwiritsa ntchito kumanga zitsulo kungathandize kusunga nthawi, kuchepetsa ndalama komanso kupewa kuwonongeka kwa zinthu. Gawo lotsatira likambirana momwe mungasankhire ndikuzigwiritsa ntchito bwino.

Chiyeso chosalowa madzi cha IP65 zikutanthauza kuti imatha kuteteza ku fumbi ndi madzi otsika mphamvu kuchokera mbali iliyonse. Chiyerekezo ichi chimapereka chitetezo champhamvu cha Fiber Termination Box, magetsi a m'munda, makamera achitetezo, mafoni ndi zida zina zomwe zimagwiritsidwa ntchito nthawi zonse panja kapena m'malo onyowa. Anthu ambiri amasankha zinthu zokhala ndi IP65 akafuna kuteteza ku mvula, madontho kapena fumbi m'moyo watsiku ndi tsiku. Zipangizo zokhala ndi chisindikizo ichi zimatha kupirira munda wonyowa, malo ochitira masewera olimbitsa thupi odzaza kapena mvula yambiri mumsewu. Opanga amayesa izi pamlingo wokhwima, kotero mutha kudalira kapangidwe kake. Kuti akuthandizeni kusankha chinthu choyenera, gawo lotsatirali likufotokoza zomwe IP65 imaphatikizapo ndikusiyanitsa ndi ziyerekezo zina kuti mutha kusankha zomwe zikugwirizana ndi zosowa zanu.

ABS ndi pulasitiki yolimba, yosagwedezeka yomwe imapangidwa posakaniza acrylonitrile, butadiene ndi styrene. Timadalira ABS muzinthu zosiyanasiyana - zida zamagalimoto, zoseweretsa, mapaipi, komanso ziwiya zina zakukhitchini. Imadziwika kuti ndi yolimba, yosavuta kupanga ikatentha komanso imatha kupirira kugwa kapena kugunda popanda kusweka. ABS ili ndi mawonekedwe osalala, zomwe zimapangitsa kuti ikhale yabwino kwambiri pazinthu zomwe zimafunika kuwoneka bwino komanso zoyera. Makina ambiri osindikizira a 3D amagwiritsa ntchito abs chifukwa imasungunuka pamalo okhazikika ndipo imasunga mawonekedwe ake. Kuti mumvetse momwe ABS imagwirizanirana ndi moyo watsiku ndi tsiku, kapena chifukwa chake imagwirira ntchito bwino kwambiri pazinthu zambiri, magawo otsatirawa akufotokoza ndi zitsanzo ndi upangiri weniweni.

Ulusi wa single mode vs. ulusi wa multimode Ndi mitundu iwiri yayikulu ya ulusi wa kuwala womwe umagwiritsidwa ntchito kutumiza deta pamtunda wautali ndi waufupi. Ulusi wa single mode umagwiritsa ntchito pakati pang'ono kwambiri ndipo umatumiza kuwala mwachindunji pansi pa pakati, zomwe zimapangitsa kuti zikhale zoyenera kulumikizana mtunda wautali pa liwiro lalikulu. Ulusi wa multimode uli ndi pakati waukulu, umafalitsa kuwala m'njira zingapo ndipo ndi woyenera mtunda waufupi monga mkati mwa nyumba kapena sukulu. Iliyonse ili ndi zabwino zake, monga mtengo, bandwidth, ndi mtunda. Kuti zikuthandizeni kusankha ulusi woyenera, magawo otsatirawa akuwonetsa zambiri zosavuta, kufananiza kagwiritsidwe ntchito, ndi kusanthula mtengo. Cholinga chake ndikupangitsa chisankhocho kukhala chosavuta komanso chodziwikiratu kwa aliyense.

Choyesera chingwe cha netiweki ya fluke chimagwiritsidwa ntchito kuyesa thanzi ndi kapangidwe ka zingwe za netiweki, kuonetsetsa kuti zikugwira ntchito bwino komanso zikutsatira zofunikira. Amalemba ntchito oyesa awa m'maofesi, masukulu ndi m'nyumba kuti adziwe zosweka, zazifupi kapena mawaya osagwira ntchito bwino mu Chingwe cha Ethernets. Oyesa a Fluke amapereka zotsatira zomveka bwino komanso zomangamanga zolimba kuti asunge nthawi ndikupewa zolakwika pokonza kapena kukonza. Oyesa ambiri amawonetsa mamapu a waya, kutalika ndi mtundu wa chizindikiro, zomwe zimathandiza ogwiritsa ntchito kuzindikira mwachangu ndikuthetsa mavuto. Kuphatikiza pa liwiro, zida monga Fluke LinkIQ ndi Fluke DSX Series ndi zosankha zodziwika bwino pakufufuza kosavuta komanso malipoti athunthu. Kuti zikuthandizeni kusankha, magawo otsatirawa akuwonetsa zinthu zofunika ndikupereka malangizo ogwiritsira ntchito.

ABS vs. Polypropylene (PP) abs ndi pp ndi awiri mwa mapulasitiki odziwika kwambiri omwe amagwiritsidwa ntchito pazinthu za tsiku ndi tsiku. ABS imatanthauza acrylonitrile butadiene styrene, pulasitiki yokhala ndi mapeto olimba komanso olimba omwe ali ndi mphamvu yabwino yogwira ntchito. PP ndi yopepuka, yosinthasintha pang'ono, ndipo imapezeka kwambiri m'mabotolo azakudya kapena nsalu chifukwa cha kutentha kwake ndi kukana mankhwala. Mapulasitiki onsewa amagwira ntchito kwambiri m'mafakitale, kuyambira magalimoto mpaka zoseweretsa. Iliyonse ili ndi zabwino zake, kaya ndi mphamvu yomanga ya ABS kapena khungu lopepuka la PP. Kumvetsetsa kusiyana pakati pa mapulasitiki awiriwa kumathandiza kusankha yoyenera ntchito iliyonse. Tsatanetsatane womalizawu ukuwonetsa momwe zipangizozi zimagwirizanirana pakugwiritsa ntchito tsiku ndi tsiku.
