Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Ikhebula le-Simplex isebenzisa i-fiber eyodwa eyisibhafa eqinile njengendawo yokuxhumana ebonakalayo, i-tight buffer fiber esongwe ngongqimba lwezintambo ze-aramid njengelungu lamandla futhi ikhebula ligcwaliswa ngejakhethi ye-TPU.
I-ultra beng enganaki yemodi eyodwa i-fiber optical BendCom® G.657.B3 inokusebenza okuvelele kokugoba, ikakhulukazi ku-5 mm ukugoba irediyasi. Ukusabalalisa kwephrofayela yenkomba ye-refractive kulungiselelwe ukuze i-fiber ihambisane ngokugcwele ne-G.657.A2 fiber, okuyenza ibe umkhiqizo ongcono kakhulu we-fiber-to-the-home (FTTH).
Isingeniso Somkhiqizo:

Izimo zohlelo lokusebenza:
1.FTTH
2.Izimo zohlelo lokusebenza lwasekhaya njengekhebula le-fiber optic elingabonakali
3.Okwezikhathi ezinezidingo ezikhethekile zokugoba irediyasi
Izici:
1. Isakhiwo esilula, isisindo esincane namandla aphezulu aqinile.
2. Idizayini ye-groove ekhethekile, ukuhlubula kalula nokuhlanganisa, ukufakwa nokugcinwa lula.
3. Izintambo ezimbili zensimbi ezihambisanayo ziqinisekisa ukushuba.
4. Ukumelana ne-Crush kanye nokuguquguquka.
5. Intuthu ephansi enguziro halogen kanye nomgodla we-flame retardant, imvelo enobungani nokuvikeleka okuhle.

Umbala wesixhumi
UKUPAKA:
1 Ubude bokuhamba bekhebula buzoba ngu-1~3 km. Obunye ubude buyatholakala futhi uma kudingwa umthengi.
2 Ubude bekhebula ngalinye buzofakwa okhunini oluqinile oluhlukile.
3 Zombili iziphetho zekhebula zizovalwa ngesivalo esifanele ukushisa esishwabenekayo 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-batten ayisiyingi 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 Ikhebuli izothunyelwa ngezigubhu eziklanyelwe ukuvimbela ukulimala kwekhebula ngesikhathi sokuthunyelwa nokufakwa
8 Ubuncane bobukhulu bomphongolo wesigubhu buzoba izikhathi ezingu-30 kububanzi bekhebula bebonke.
