Mukugadzirwa kwetambo dze optical fiber (OFC), kusarudza zvinhu zvakagadzirwa zvakanaka kwakakosha. Nzvimbo dzakasiyana dzekushanda—dzakadai sekutonhora kwakanyanya, tembiricha dzakakwirira, hunyoro, kuiswa panze, kukotama nguva dzose, kana kufamba-famba kakawanda—zvinoda zvinhu zvakasiyana-siyana patambo dze optical. Pano, tinopfupikisa zvinhu zvinoverengeka zvinoshandiswa zvakanyanya muindasitiri, tichiongorora mashandiro azvo uye mashandisirwo azvo kuti zvikubatsire kugadzirisa dhizaini yako yetambo dze optical fiber uye kusarudzwa kwezvinhu.
1. PBT (Polybutylene Terephthalate) — Chinhu Chinonyanya Kushandiswa Pamachubhu Akasununguka
PBTndiyo inonyanya kushandiswa pakugadzira machubhu asina kusimba mutambo dzefiber dzinopenya. Mapurasitiki etambo akajairika anowanzo pfava patembiricha yakaderera uye anopfava patembiricha yakakwirira. PBT yakagadziridzwa, semuenzaniso ine zvikamu zvecheni zvinochinjika, inovandudza zvakanyanya kusimba kwekupisa kwakaderera uye inogona kusangana nezvinodiwa kusvika -40°C. Pamusoro pezvo, PBT inopa kusimba kwakanaka uye kugadzikana kwehukuru patembiricha yakakwirira, ichivimbisa dziviriro yakavimbika kune fibers pasi pekumanikidzwa kwekupisa. Kushanda kwayo kwakaringana, mutengo unonzwisisika, uye kushanduka-shanduka kunoita kuti ive sarudzo yakajairika yetambo dzekutaurirana dzekunze, tambo dzinofamba kwenguva refu, uye zvivakwa zvetambo dzeADSS.
2. PP (Polypropylene) — Kusimba Kwepamusoro-soro Pakupisa Kushoma uye Kuramba Kunyungudika Kwemvura
PP yawana mukurumbira mumidziyo yetambo dzemagetsi nekuda kwekusimba kwayo kwakanyanya pakupisa kwakaderera, ichidzivirira kutsemuka mumamiriro ekunze anotonhora zvikuru. Kusagona kwayo kushandisa hydrolysis kwakanyanyawo kupfuura PBT, zvichiita kuti ive yakakodzera munzvimbo dzine hunyoro kana dzine mvura yakawanda. Zvisinei, PP ine modulus yakaderera uye kuomarara zvishoma kana ichienzaniswa nePBT, saka kushandiswa kwayo kunofanira kufunga nezvechimiro chetambo chaiyo. Semuenzaniso, tambo dzakareruka, tambo dzemukati nekunze dzakasanganiswa, kana zvivakwa zvemachubhu akasununguka zvinoda kuchinjika kwakanyanya zvinogona kusarudza PP seimwe nzira.
3. LSZH (Low Smoke Zero Halogen) — Chinhu Chinochengetedza Ruzivo Rwepasi Pese
LSZHndiyo inonyanya kushandiswa nejaketi retambo risingakuvadzi nharaunda. Mafomula eLSZH emhando yepamusoro, anowanikwa kuburikidza nemasisitimu epolymer akasarudzika uye matekinoroji ekuzadza, anogona kusangana nezvinodiwa nekupisa kwakaderera kwe -40°C uye anogona kushandiswa kwenguva refu pa85°C. Kana paine moto, LSZH inoburitsa utsi hushoma uye isina magasi e halogen, zvichiwedzera kuchengetedzeka kwetambo dzemukati, tambo dzedata centre, uye waya dzevashandi veruzhinji. Inopawo kudzivirira kwakanyanya kupwanyika kwekumanikidzwa kwezvakatipoteredza uye ngura yemakemikari, zvichiita kuti ive sarudzo inoshanda zvakasiyana-siyana yejaketi dzetambo dzemukati nedzekunze.
4. TPU (Thermoplastic Polyurethane) — "Mambo" weKuchinjika Kwekupisa Kushoma uye Kuramba Kukweshana
TPU inozivikanwa nekuchinjika kwayo uye kusimba kwayo kana tembiricha yakaderera. Kusiyana nePVC, TPU inoramba yakapfava uye haitsemuke. Inewo simba rekudzivirira kukwesha, mafuta, uye kubvaruka, zvichiita kuti ive yakakodzera tambo dzinofambiswa, dzinosanganisira tambo dzekudhonza, tambo dzemotokari, tambo dzemigodhi, tambo dzerobhoti, uye mashandisirwo emagetsi eindasitiri. Ziva kuti kudzivirira kupisa kwakanyanya uye hydrolysis kweTPU kunoenderana negiredhi chaiyo, saka kusarudza mafomula emhando yepamusoro kwakakosha.
5. PVC (Polyvinyl Chloride) — Sarudzo yeJaketi reCable Rinoshanda Mari Yakawanda Nekudzikamiswa Kwekupisa Kushoma
PVC ichiri kushandiswa kune dzimwe tambo dze optical nekuda kwemutengo wayo wakaderera uye nyore kushandisa. Zvisinei, PVC yakajairwa inooma uye inogona kutsemuka pasi pe -10°C, zvichiita kuti isakodzere mamiriro ekunze anotonhora zvakanyanya. PVC isingatonhori kana kuti isingatonhori inogona kuderedza tembiricha yekuchinja kwegirazi kuburikidza nema plasticizers, asi izvi zvinogona kukanganisa simba remakanika uye kuramba kukwegura. Saka PVC yakakodzera zvirinani kumapurojekiti anonyanya kudhura munzvimbo dzakagadzikana, dzakadai sekuisa mukati meimba kana kugadzirisa tambo kwenguva pfupi.
6. TPV (Thermoplastic Vulcanizate) — Kubatanidza Rubber Elasticity uye Plastiki Kugona Kugadziriswa
TPV inosanganisa kusimba kwerabha nekugona kugadzikiswa kwepurasitiki. Inopa kusimba kwakanaka kwazvo pakupisa kwakanyanya uye kwakaderera, pamwe nekusimba kwakanyanya kwemamiriro ekunze uye kudzivirira ozone. Kusimba uye kusimba kweTPV kunoita kuti ive yakakodzera tambo dzekunze dzemagetsi, waya dzemotokari, uye tambo dzinochinjika. Sechinhu, TPV inoenzanisa hunhu hweTPU nePVC, ichipa kusimba kwakanaka kwechimiro uye kusimba kwezvakatipoteredza.
7. XLPE (Crosslinked Polyethylene) — Zvinhu Zvinodzivirira Kupisa Kwakanyanya zveMatambo Emagetsi Nemagetsi
XLPE, kuburikidza nekubatanidza, inowedzera kudzivirira kupisa uye inogona kushanda nguva dzose pamusoro pe90°C. Inopawo simba remakanika uye kudzivirira kushushikana kwakanyanya. Kunyange zvazvo XLPE ichinyanya kushandiswa pakudzivirira tambo dzemagetsi (semuenzaniso, 1kV–35kV), dzimwe nguva inoshandiswa mutambo dzeoptical kusimbisa kana kushandisa tembiricha yepamusoro. Hunhu hwayo hwekupisa uye hwemakanika hunoita kuti ikodzere tambo dzeoptical dzakagadzirwa munzvimbo dzakaoma.
Kusarudza Zvinhu zveOptical Cable Jacket — Maitiro ekushandisa Ndiwo Akakosha
Kusarudza zvinhu zvetambo dze optical zvakakodzera kunoda zvinopfuura kungoongorora ruzivo rwehunyanzvi; kunofanirawo kufunga nezvemamiriro chaiwo ekushandiswa:
Kuiswa Kwakagadziriswa (kunze, duct, aerial): LSZH, TPV, XLPE
Mashandisirwo Ekufambisa (cheni dzekudhonza, marobhoti, mota, migodhi): TPU
Kutonhora Kwakanyanya (-40°C kana pasi): PBT Yakagadziriswa, PP, TPU
Kuisa Tabhu Mumba, Kushandiswa Kwakajairika, Mapurojekiti Anonyanya Kudhura: PVC (inokurudzirwa chete mumamiriro ezvinhu chaiwo)
Hapana mhinduro "inokodzera zvese" yezvinhu zvetambo dze optical. Sarudzo yacho inofanira kunge yakavakirwa pakuongorora kwakazara kwechimiro chetambo, mamiriro ekuisa, bhajeti, uye kuvimbika kwenguva refu.
