Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Iyunithi ye-fiber optical ibekwe phakathi nendawo.I-Fiber Reinforced Plastics(FRP) emibili ehambisanayo ibekwe ezinhlangothini ezimbili.Izintambo zensimbi njengoba kusetshenziswa ilungu elinamandla engeziwe. Khona-ke ikhebula liqedwa ngombala omnyama noma we-LSZH sheath.Ikhebula lisetshenziswa kakhulu kuphrojekthi ye-FTTH.
Izici:
1. I-Specail low-bend-sensitivity fiber inikeza i-bandwith ephezulu kanye nempahla yokudlulisela yokuxhumana enhle kakhulu;
2. Amalungu amabili ahambisanayo wamandla e-FRP aqinisekisa ukusebenza kahle kokumelana nokuchoboza ukuvikela i-fiber;
3. Isakhiwo esilula, isisindo esincane kanye nokusebenza okuphezulu;
4. Amamasaji njengelungu elengeziwe lamandla aqinisekisa ukusebenza kahle kwamandla aqinile;
5. Idizayini yomtshingo inoveli, ukuhlubula kalula nokuhlanganisa, ukwenza kube lula ukufakwa nokulungisa;
6. Intuthu ephansi, i-halogen enguziro kanye nesigodlo se-flame retardant.
7. I-Anti Twisting Self-sustainment Fiber optical Cable
Ukucaciswa kobuchwepheshe:
| Into | Ipharamitha yobuchwepheshe |
| Ukucaciswa kwekhebula | I-GJYXCHN-1~12B6a2 |
| Umbala wefiber | Imvelo (noma wenze ngendlela oyifisayo) |
| Uhlobo lwefiber | 9/125 (G657A2) |
| Umbala we-sheath | Mnyama |

Qaphela: umkhiqizo uhambisana nemiyalelo ye-EU RoHS
UKUPAKA:
1.Ubude bokuhamba bendawo bekhebula buzoba ngu-1~3 km. Obunye ubude buyatholakala futhi uma kudingwa umthengi.
2.Ubude bekhebula ngalinye buzofakwa okhunini oluqinile oluhlukile.
I-3.Zombili iziphetho zekhebula zizovalwa nge-cap efanelekayo yokushisa enciphisa ukushisa ukuze kuvinjelwe ukungena komswakama ngesikhathi sokuthutha nokugcinwa.
4.Isiphetho sekhebula sizoboshelwa ngokuvikelekile kusigubhu ukuze kuvinjwe ikhebula ukuthi lingaxegi ngesikhathi sokuthutha noma lixege phakathi nokubeka imisebenzi.
5.Ama-battens we-circumference azovikelwa phakathi kwamaphethelo angaphandle e-flange ukuze kuvikelwe intambo emonakalweni ngesikhathi sokuthunyelwa nokugcinwa.
6.Ngezinjongo zokuhlola, isiphetho sangaphakathi sekhebula sizohlehliswa sibe yimbobo ku-drum flange . Ubude obuncane bemitha eyodwa yekhebula ekugcineni kwangaphakathi buzofinyeleleka.
7.Intambo izothunyelwa ngezigubhu eziklanyelwe ukuvikela ukulimala kwentambo ngesikhathi sokuthunyelwa nokufakwa.
8.Ubukhulu obuncane bomphongolo wesigubhu buzoba izikhathi ezingu-30 kububanzi bekhebula lilonke.
