PVC, kana kuti polyvinyl chloride, ipurasitiki inoshandiswa zvakanyanya—kubva papombi kusvika kuzvipfeko. Yakagadzirwa kubva kuvinyl chloride, PVC inozivikanwa nekugara kwayo kwenguva refu, huremu hwayo hushoma uye mutengo wayo wakaderera. Vanoishandisa mudzimba, mumafuremu emahwindo uye kunyange makadhi echikwereti. Haina ngura, saka inogara kwenguva refu munzvimbo dzine mvura. PVC inogona kugadzirwa yakapfava kana kuti yakaoma izvo zvinoita kuti ishandiswe zvakanyanya pasi rose. Vamwe vagadziri vanowedzera zvimwe zvinhu kuti vashandure kupfava kwayo kana kuoma kwayo. Nekushandiswa kwayo kwakasiyana-siyana, PVC yakachinja maitiro atinovaka, kugadzira, uye kunyange kuchengetedza. Chinyorwa chinotevera chinotsanangura kuti polyvinyl chloride inogadzirwa sei uye kuti inoonekwa sei muhupenyu hwezuva nezuva.

Fiber optic itambo inotumira data semapundu echiedza pamusoro pemagirazi kana mapurasitiki. Inofamba nemasaini nekukurumidza uye munzvimbo dzakakura kupfuura tambo dzemhangura dzekare. MaISP akati wandei atove achipa fiber optic yekumhanya nekukurumidza uye kwakavimbika kumba nebasa. Tambo idzi dzakatetepa asi dzakasimba, dzimwe nguva hadzina kukwira kupfuura tambo yebvudzi. Hadzipindirwi netambo dzemagetsi kana mamiriro ekunze, saka dzinoramba dzakagadzikana chero kupi. Fiber optic ikozvino yakabatanidzwa mune zvakawanda, zvakaita semavhidhiyo ekuteerera, mafoni evhidhiyo, uye storage yegore. Kuti tiratidze mashandiro anoita fiber optic uye nei ichikosha, zvikamu zvinotevera zvinotsanangura zvakakosha uye mashandisirwo azvo.

Kusunga simbi simbi tambo yakasimba kwazvo, yakati sandara inoshandiswa kusunga zvinhu zvinorema kuti zvichengeterwe kana kutumirwa. Ingava mumatura, mafekitori, kana kunyange muzvitoro zvidiki, kusunga simbi kunochengetedza zvinhu zvakachengeteka uye zvakagadzikana paunenge uchifamba. Basa rayo guru nderekubatanidza zvinhu zvakakura, zvakaita sematanda, mapaipi, kana zvinhu zvemakanika, kuita pakeji yakanaka, diki. Nesimba rakasimba uye rinogara kwenguva refu, kusunga simbi kwakanakira mabasa apo tambo dzepurasitiki kana dzemachira dzinokundikana. Vashandi vazhinji vanosarudza kusunga simbi kumapurojekiti anoda kutariswa zvakanyanya, akadai sekutumira zvinhu kunze kwenyika kana kutakura zvinhu zvakapinza. Kuziviswa nezvenguva uye nei kushandisa kusunga simbi kunogona kubatsira mukuchengetedza nguva, kuderedza mari uye kudzivirira kukuvara kwezvinhu. Chikamu chinotevera chichakurukura kuti ungasarudza sei uye kushandisa sei zvinobudirira.

Chiyero chemvura cheIP65 zvinoreva kuti inogona kudzivirira kubva kuguruva uye majeti emvura ane simba shoma kubva chero kupi. Chiyero ichi chinopa dziviriro yakasimba yeFiber Termination Box, marambi emubindu, makamera ekuchengetedza, mafoni nezvimwe zvinoshandiswa nguva dzose kunze kana munzvimbo dzakanyorova. Vanhu vazhinji vanosarudza zvigadzirwa zvine IP65 pavanenge vachida kudzivirira kubva kunaya, kupwanyika kana guruva muhupenyu hwezuva nezuva. Midziyo ine chiyero ichi chechisimbiso inogona kutsungirira bindu rakanyorova, nzvimbo yekuchengetera zvinhu yakazara kana mvura mumugwagwa. Vagadziri vanoiedza kusvika padanho rakasimba, saka unogona kuvimba nekuvakwa kwayo. Kuti ikubatsire pakusarudza chigadzirwa chakakodzera, chikamu chinotevera chinotsanangura zvinosanganisirwa neIP65 uye chinoisiyanisa nezvimwe zviyero kuitira kuti ugone kusarudza zvinokunakira.

ABS ipurasitiki yakasimba, inodzivirira kukuvadzwa yakagadzirwa nekusanganisa acrylonitrile, butadiene uye styrene. Tinovimba neABS muzvinhu zvakasiyana-siyana - zvikamu zvemotokari, matoyi, mapaipi, uye kunyange mimwe midziyo yekicheni. Inozivikanwa nekusimba kwayo, inogadzirwa nyore nyore kana ichidziya uye inokwanisa kutsungirira kudonha kana kukuvadzwa pasina kutsemuka. ABS ine magumo akatsetseka, izvo zvinoita kuti ive yakanaka kune zvigadzirwa zvinoda kutaridzika zvakanaka uye zvakachena. Mazhinji maprinta e3D anoshandisa abs nekuti inonyunguduka panzvimbo imwe chete uye inoramba iri muchimiro chayo. Kuti unzwisise kuti ABS inokodzera sei muhupenyu hwezuva nezuva, kana kuti nei ichishanda zvakanaka kune akawanda maapplication, zvikamu zvinotevera zvinotsanangura nemienzaniso nemazano epasirese.

Fiber yemodhi imwe chete vs. faibha yemhando dzakasiyana-siyana Ndiwo marudzi maviri makuru efibers dze optical dzinoshandiswa kutumira data munzvimbo refu nepfupi. Single mode fiber inoshandisa core diki uye inotumira chiedza zvakananga pasi pecore, zvichiita kuti ive yakakodzera kutaurirana kure nekumhanya kwakanyanya. Multimode fiber ine core yakakura, inoparadzira chiedza munzira dzakawanda uye yakakodzera daro pfupi senge mukati mechivako kana campus. Imwe neimwe ine zvayakanakira, zvakaita semutengo, bandwidth, uye daro. Kuti ikubatsire pakusarudza fiber yakakodzera, zvikamu zvinotevera zvinopa ruzivo rwakajeka, kuenzanisa mashandisirwo, uye kuongorora mitengo. Chinangwa ndechekuita kuti sarudzo ive nyore uye pachena kune wese munhu.

Chishandiso chekuongorora tambo dzemagetsi chinoshandiswa kuyedza hutano uye mamiriro etambo dzemagetsi, kuve nechokwadi chekuti dzinoshanda nemazvo uye dzinotevedzera zvinodiwa. Vanoshandisa vaongorori ava mumahofisi, muzvikoro nemudzimba kuti vaone maburi, mapfupi kana kuti waya dzisina kunaka mumagetsi. Tambo yeEthernets. Vayedzi veFluke vanopa mhedzisiro yakajeka uye kuvaka kwakasimba kuchengetedza nguva uye kudzivirira zvikanganiso pakugadzirisa kana kugadzirisa. Vayedzi vazhinji vanoratidza mamepu ewaya, kureba uye hunhu hwechiratidzo, zvichibvumira vashandisi kukurumidza kuona nekugadzirisa matambudziko. Pamusoro pekumhanya, maturusi akaita seFluke LinkIQ neFluke DSX Series anonyanya kufarirwa pakutarisa zviri nyore uye mishumo yakazara. Kuti zvikubatsire pakusarudza, zvikamu zvinotevera zvicharatidza maficha akakosha uye zvinopa mazano ekushandisa.

ABS vs. Polypropylene (PP) abs uye pp ndiwo maviri emapurasitiki anonyanya kushandiswa muzvigadzirwa zvezuva nezuva. ABS zvinoreva acrylonitrile butadiene styrene, purasitiki ine magumo akaomarara uye ane simba rakanaka rekubata. PP yakareruka, inochinjika zvishoma, uye inowanzo kuwanikwa mumidziyo yechikafu kana machira nekuda kwekupisa kwayo uye kusadzivirira makemikari. Mapurasitiki ese ari maviri anoshanda zvakanyanya mumaindasitiri, kubva kumotokari kusvika kumatoyi. Imwe neimwe ine zvayakanakira, ingave kugona kwayo kuvaka kwakasimba kweABS kana ganda rayo rinopfava, rePP. Kunzwisisa mutsauko unoshanda pakati pemapurasitiki maviri aya kunobatsira mukusarudza rakakodzera chero basa. Ruzivo rwekupedzisira runoratidza kuti zvinhu izvi zvinosanganiswa sei mukushandiswa kwezuva nezuva.
