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.
6.Assemble tūhono
7.Grinding muka whatu mutunga: SC / APC me SC / UPC tukanga huri rerekē.Me ki kia whenua tūhono muka whatu. He rereke te Koki o te huri ki te hono.
8. Tirohia me te whakamatautau. Me 100% te mutunga o te tirotiro me nga raraunga whakamatautau mo ia hononga
