Isikhathi esincane emsebenzini sisho ukwehla kwengozi yabasebenzi kanye nokuncipha kwesikhathi sokungasebenzi kwabasebenzisi bezintambo. Ukusebenzisa izinsimbi ezimbalwa nezinto eziphinde zasetshenziswa kuzuzisa iplanethi futhi kunganciphisa izindleko ngokuhamba kwesikhathi. Ezinye zezintambo zethu ezintsha zenzelwe ngisho nokuvuselelwa okulula lapho zifika ekupheleni komjikelezo wazo wokuphila.

Zonke lezi zinguquko zibeka i-fiber endaweni evelele kakhulu yamanethiwekhi esikhathi esizayo, kokubili ezokuxhumana kanye nokudluliselwa kukagesi. Ngezintambo eziqinile, ezisindayo, nezihlakaniphile, amanethiwekhi angafinyelela kude futhi asebenze kahle kakhulu, esekela imiphakathi yasemadolobheni kanye neyasemakhaya ngokufanayo ukuthi ixhunywe.

Isiphetho

I-ADSS vs OPGW akudingeki ibe yimpicabadala. Zombili izintambo zenza imisebenzi ebalulekile kumagridi kagesi. I-ADSS ikhanya kakhulu emizileni evinjiwe kakhulu. I-OPGW ifanelana kahle nemigqa enamandla kagesi aphezulu. Ikhebula ngalinye lithwala inani lalo, kusukela esivinini sokufakwa kwalo kuya ezidingweni zalo zokulungisa. Amaqembu amaningi abheka imithetho yokuphepha, izindleko, kanye nokuphuthuma. Amagridi ahlakaniphile kanye nobuchwepheshe obusha bayaqhubeka nokuhambisa amathuba womabili phambili. Ensimini, amaqembu athola izinzuzo ezibonakalayo ngokwenza ukukhetha okufanele. Amaqembu alinganisela izidingo, ukwakheka kwendawo, kanye nezinhloso zesikhathi esizayo ayizinqumo ezinhle. Bheka ngokucophelela izinhloso zakho zegridi kanye nezidingo zendawo, bese uthintana nochwepheshe wekhebula ukuze uthole ikhambi elifanele.

imibuzo ejwayelekile ukubuzwa

Uyini umehluko omkhulu phakathi kwezintambo ze-ADSS ne-OPGW?
