ＳＣ / AＰＣ-SC / APCPre-Ihuza Optical Fibre Drop Cable itanga precess
1. Umugozi wa FTTH uciwe muburebure butandukanye ukurikije ibipimo byumugozi, mubisanzwe kuva kuri 1m kugeza 300m, ariko turashobora kandi gukata dukurikije ibindi bisabwa.Nintambwe yambere mugukora umugozi.
2. Shira ibikoresho bya connexion mbere, mbere yo gukuramo fibre optique.
3.Kuramo fibre optique hanyuma ushire 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 gutunganya ingingo hamwe na kole idasanzwe.Hano, igihe cyo gukira ni isaha imwe nigice.Twongereye igihe cyo gukiza kandi twongere imbaraga zingana nubunini bwibice byicyuma.
5.Guhuza gukosorwa: Iyi nzira ni ngombwa cyane, igena imbaraga zo guhangana.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. Reba kandi ugerageze.Buri muhuza asaba 100% yo kugenzura no gusuzuma amakuru
