Whakataka te tukanga hua papaki taura FTTH.

SC/APC-SC /APCPre-Hononga Orotika Whakataka Whakataka Taura ka whakaputa i mua

 

1. Ka tapahia te taura FTTH ki nga roa rereke e ai ki nga whakaritenga taura papaki, ko te tikanga mai i te 1m ki te 300m, engari ka taea ano e tatou te tapahi kia rite ki etahi atu whakaritenga. Koinei te mahi tuatahi ki te hanga i te taura papaki.

2. Whakatakotoria he taputapu tūhono i mua, i mua i te tangohanga i te muka whatu.

3. Tihorea te muka whatu ka whakakakahu takitahi ki runga i nga taputapu hono. Me waiho te roa o te muka whatu ki te taha kia pai ai nga mahi o muri mai.

4.hoting whakakoi: Kia taea ai te kaha o te kaha o te hononga ki te 120N, me whakatika e tatou te hononga ki te kopa motuhake. I konei, kotahi me te hawhe haora te wa whakaora. Ka whakaroahia e matou te wa whakaora me te whakanui ake i te kaha o te kaha ki te rahi o nga waahanga rino.

5.Joint kua whakaritea: He mea tino nui tenei tukanga, e whakatau ana i te kaha o te aukati tahi. Kua whakaroahia e matou te rahi o te pepa rino me te whakanui ake i te nui o te kapia, kia kaha ake te pupuhi o te hononga.
