Mukutumira nekugadzira ruzivo, Optical Fiber Cables (OFCs) dzinoita basa rakakosha. Dzinoonekwa senzira dzekutaurirana nefoni. Saka, zvakakosha zvikuru kuti dzivimbise kubatana kwakachengeteka nguva dzese. Zvisinei, dzimwe nguva, nguva yekushanda kweOFC inogona kutyisidzirwa nemakonzo, semuenzaniso kana maOFC akaiswa mumapaipi anowanikwa nemakonzo zviri nyore. Munzvimbo dzakadaro maOFC anofanirwa kuchengetedzwa, nekuti makonzo ane mukana wekuruma nekurwisa maOFC kana kubuda kwawo kwavharwa mumapaipi aya.

Kuti tambo dzive dzakagadzirwa zvakanaka, vagadziri vetambo vanosarudza kushandisa chinhu chinosanganisa zvinhu zvinosimbisa nekudzivirira makonzo. Vanodawo kuti maOFC ave akapfava uye akareba, uye ave nedhayamita diki. Zvinhu zvinosimbisa maOFC e dielectric zvinonyanya kuve aramid neE-glass zvishoma. Kushandiswa kwearamid kwakakurumbira uye kuri kuwedzera nekukurumidza nekuda kwekusanganiswa kwayo kusingaenzaniswi kwehunhu hwemakanika nemakemikari uye hunhu hwayo hwakanaka hwekugadzirisa, zvichikonzera kuti maOFC anodhura zvishoma ane mashandiro akanaka uye akavimbika kwenguva refu. Zvisinei, mubvunzo wekuti E-glass nearamid zvinochengetedza kudzivirirwa kwakakwana kwemakonzo wagara uchimuka. Zvaive zvakaoma kuwana mhinduro yakajeka kubva kune vashandisi veOFC. Zvakaitika kune vashandisi veOFC muSwitzerland semuenzaniso, zvakaratidza kuti mune dzimwe nguva tambo dzeE-glass nearamid dzakasimbiswa dzakakuvadzwa zvakanyanya nemakonzo zvekuti hadzisisina kushanda zvakanaka. Kuti tijekese mamiriro ezvinhu panyaya yekudzivirira makonzo uye kutsigira vagadziri veOFCs dzemagetsi, takasarudza pamwe chete nemumwe wevatengi vedu vekuSwitzerland kuti tifonere sangano rekutsvagisa rakazvimirira, TNO (sangano rekuDutch rekutsvaga kwesainzi), kuti riite ongororo pasi pemamiriro ezvinhu anoshanda kuti tiedze kuramba kwekonzo kwemarudzi akasiyana eOFCs.

2. Kuedza

Kugadzirira bvunzo

Kuti vaedze kudzivirira kweOFCs, TNO yakashandisa makonzo eSprague Dawley akaiswa mumakeji akagadzirirwa chidzidzo ichi. Makeji aya akakamurwa kuita zvikamu zviviri kuburikidza nechikamu chakapihwa buri rakatenderera rekubatanidza zvikamu zviviri (ona Mufananidzo 1). Rimwe remakeji rakavhenekerwa uye rimwe rakasviba. Munguva yekuedzwa, kupinda kwechikamu chakasviba, umo chikafu chemakonzo chaiva, kwakavharirwa neOFCs pakuedzwa. Sezvo makonzo achida nzvimbo ine rima, anopedza nguva yakawanda ari kudivi rerima. Saka, paiva nezvikonzero zviviri zvekuti makonzo apinde muchikamu chakasviba. Munguva yese yekuedzwa, makonzo aiwana mvura yakasununguka. Mushure mekunge makonzo ajaira mamiriro ari mumakeji, miedzo yekutanga yakatanga.

Mufananidzo 1: Keji yekuyedza yakakamurwa kuita zvikamu zviviri.

Pakutanga kwemiedzo, makonzo matatu akaiswa muzvikamu zvakavhenekerwa zvekeji yega yega kwemazuva maviri akatevera, nepo gomba riri muchikamu rakavharirwa nedhizaini yeOFC pakuedzwa (ona Mufananidzo 2). Mushure menguva iyi makonzo akatamisirwa kune mamwe makeji kwemazuva mana uye akazodzoserwa kumakeji ekuyedza kwemazuva maviri ekuwedzera.

Mufananidzo 2: Buri riri muchikamu chakavharwa neOFCs pakutongwa.

Magadzirirwo eOFC akaongororwa

Magadzirirwo mapfumbamwe akasiyana eOFC akaongororwa kuti aone kana makonzo asingakuvadzi. Magadzirirwo aya ese ari muboka remagadzirirwo anomiririra chikamu chikuru chemusika weOFC. MaOFC anogona kukamurwa kuita mapoka maviri:

1. Magadzirirwo eOFC akajairwa achishandisa waya yearamid kana girazi reE (rine kana risina impregnation) sechinhu chinosimbisa pasi pePE outer sheath (Mifananidzo 3a kusvika 3d).

2. Magadzirirwo eOFC akakosha ekudzivirira kurwiswa nemakonzo, semuenzaniso zvivakwa zvine mativi maviri kana zvivakwa zvine PA12 kana simbi yakarukwa (Mifananidzo 3e kusvika 3i).

Mufananidzo 3a: Chikamu chakachinjika chedhizaini yakajairika yeOFC. Mufananidzo 3b: Chikamu chakachinjika chedhizaini yakajairika yeOFC.

Mufananidzo 3c: Chikamu chakachinjika chedhizaini yakajairika yeOFC.Mufananidzo 3d: Chikamu chakachinjika chedhizaini yakajairika yeOFC.

Mufananidzo 3e: Chikamu chemuchinjiko chedhizaini yakakosha yeOFC.Mufananidzo 3f: Chikamu chemuchinjiko chedhizaini yakakosha yeOFC.

Mufananidzo 3g: Chikamu chemuchinjiko chedhizaini yakakosha yeOFC.Mufananidzo 3h: Chikamu chemuchinjiko chedhizaini yakakosha yeOFC.

Mufananidzo 3i: Chikamu chemuchinjiko chedhizaini yakakosha yeOFC.

3. Mhedzisiro nehurukuro

Mushure memazuva maviri ekuyedza emazuva maviri, kukuvara kunokonzerwa nekurwiswa nemakonzo kwakaongororwa. MuMifananidzo 4a kusvika 4i muchaona mifananidzo miviri yemagadzirirwo etambo imwe neimwe yakaedzwa; mufananidzo wepamusoro unoratidza usina kukuvara zvakanyanya uye wepasi unoratidza OFC yakanyanya kukuvara. Mhedzisiro yekuongororwa kwemakonzo akawanda inoratidza zvakajeka mutsauko mukukuvadzwa pakati pemagadzirirwo mapfumbamwe eOFC. Asi, sezvamunoona mumifananidzo, maOFC ese - kunze kwekugadzirwa kwesimbi yakakombama/aramid - akakuvara nenzira yekuti munhu angatarisira kuti hunhu hwekutumira kwenguva refu hukanganiswe. Izvi zvinoshandawo kune magadzirirwo eOFC PE/impregnated E-glass/water-blocking tape (Mufananidzo 4d) uye PE/impregnated E-glass strands/PE/aramid (Mufananidzo 4h), kunyangwe magadzirirwo aya achiratidza kukuvara kushoma. Mukuita, zvakadaro, munhu anobata nemakonzo asiri epamba, izvo zvinogona kusanganisira kurwisa kwakanyanya uye kunoramba kuripo kana mbeva ikasungwa. Saka, zvichibva pamhedzisiro yebvunzo yeTNO, mhedziso inofanira kunge iri yekuti pamagadzirirwo akaedzwa dhizaini yesimbi yakakombama/aramid chete ndiyo inodzivirira makonzo zvachose.

Kusasimba kwembeva dzeOFC kunogonawo kuvandudzwa nekushandisa masheath ekunze akagadzirwa neamorphous polyamide kana polyamide copolymers ane kuomarara kwakanyanya kweShore D. Nokudaro, tinokurudzira vagadziri vetambo kuti vavandudze kusasimba kwembeva dzeOFCs nekushandisa corrugated steel (semuenzaniso Zetabon) kana masheath akagadzirwa neamorphous polyamide kana polyamide copolymers (semuenzaniso Grilamid). Kushandiswa kwecorrugated steel kunoita sekunge ndiyo sarudzo yakanakisisa.

Pfungwa yekuti dhayamita yetambo inokanganisa kuramba kwembeva kweOFC - zvichireva kuti kubva pane imwe dhayamita yetambo zvichienda mberi pane simba rakanaka pakuramba kuramba kwembeva - inonakidza uye kudzidza kwakawedzerwa kunogona kubatsira vagadziri vetambo.

Mufananidzo 4a: Dhizaini yetambo yePE/aramid mushure mekuyedzwa; dhayamita 13.5 mm.

Mufananidzo 4b: Dhizaini yetambo yegirazi reE-girazi rakaiswa PE/yakaiswa mumvura mushure mekuyedzwa; dhayamita 11.8 mm.

Mufananidzo 4c: Dhizaini yetambo yePE/E-girazi mushure mekuyedzwa; dhayamita 9.5 mm.

Mufananidzo 4d: Dhizaini yetambo yePE/girazi reE/rinovhara mvura mushure mekuyedzwa; dhayamita 15.5 mm.

Mufananidzo 4e: Dhizaini yetambo yePE/girazi reE/PE/aramid yakanyudzwa mushure mekuyedzwa; dhayamita 8.8 mm.

Mufananidzo 4f: Dhizaini yekebhu yePE/aramid/PE/aramid mushure mekuyedzwa; dhayamita 21 mm.

Mufananidzo 4g: Dhizaini yetambo yePE/PA12/aramid mushure mekuyedzwa; dhayamita 8.5 mm.

Mufananidzo 4h: Dhizaini yetambo yePE/yegirazi reE/yearamid mushure mekuyedzwa; dhayamita 15.7 mm

Mufananidzo 4i: Dhizaini yetambo yePE/simbi yekongiri/PE/aramid mushure mekuyedzwa; dhayamita 14.7 mm.

4. Mhedziso

Zvichibva pamhedzisiro yemiedzo, TNO yakagumisa kuti pamagadzirirwo eOFC akaedzwa, dhizaini yesimbi/aramid chete ndiyo inodzivirira makonzo zvachose. Mamwe magadzirirwo ese (akasimbiswa negirazi reE rine kana risina kuisirwa- kana aramid, kana nesheath yePA12) haana kudzivirira zvakakwana kurwiswa nemakonzo. Chidzidzo ichi chinoratidza zvakajeka kuti kana kuramba makonzo kuchidikanwa, munhu anofanira kunyatsoteerera dhizaini yetambo.
