1. Umugozi wa FTTH uciwe muburebure butandukanye ukurikije ibisabwa byumugozi, mubisanzwe kuva kuri 1m kugeza 300m, ariko turashobora kandi guca dukurikije ibindi bisabwa. Nintambwe yambere mugukora umugozi.
2. Shira ibikoresho bihuza mbere, mbere yo gukuramo fibre optique.
3.Kuramo fibre optique hanyuma ushyire kumurongo uhuza umwe umwe. Uburebure bwa fibre optique bugomba gushyirwa kuruhande kugirango byorohereze ibikorwa.
4.kurasa gukomera: Kugirango tumenye neza ko imbaraga zingana zingingo zishobora kugera kuri 120N, dukeneye gukosora ingingo hamwe na kole idasanzwe. Hano, igihe cyo gukira ni isaha imwe nigice. Twongereye igihe cyo gukira kandi twongere imbaraga zingana nubunini bwibice byicyuma.
5.Guhuza gukosorwa: Iyi nzira ningirakamaro cyane, igena imbaraga zo guhangana hamwe. Twongereye ubunini bw'urupapuro rw'icyuma kandi twongera ubwinshi bwa kole, kugirango ingingo irusheho gukomera.
6.Guteranya umuhuza
7.Gusya fibre optique iherezo: SC / APC na SC / UPC Uburyo butandukanye bwo gusya.Buri buhuza fibre optique igomba kuba hasi. Inguni yo gusya iratandukanye nu muhuza.
8. Kugenzura no kugerageza. Buri muhuza asaba 100% yo kugenzura no kurangiza amakuru
