Nkuko twese tubizi ko inkuba ari isohoka ryamashanyarazi yo mu kirere iterwa no kwiyongera kwamafaranga atandukanye mu gicu.Igisubizo ni ukurekura gutunguranye kwingufu zitera urumuri rwihariye, rukurikirwa ninkuba.
Kurugero, ntabwo bizagira ingaruka kumiyoboro ya fibre ya DWDM gusa mugihe gito, ahubwo izagira ingaruka kumyerekano icyarimwe ukurikije ubushakashatsi bwinshi.Ndetse bizatera umuriro mugihe hari imirabyo ikabije.Nubwo ibimenyetso biri mumigozi ya fibre ari ibimenyetso bya optique, ibyinshi mumigozi yo hanze yo hanze ukoresheje cores zongerewe imbaraga cyangwa insinga za optique byoroshye byoroshye kwangirika munsi yumurabyo kubera icyuma kirinda icyuma imbere.Kubwibyo, ni ngombwa kubaka sisitemu yo gukingira inkuba kurinda insinga zikingira.
Igipimo cya 1:
Kurinda inkuba kumurongo ugororotse wumurongo wa optique: ①Mu biro byubutaka bwo mu biro, ibice byicyuma mumashanyarazi ya optique bigomba guhuzwa hamwe, kugirango ibice byongera imbaraga, bitarimo ubushuhe hamwe nintwaro zicyiciro cya relay ya optique umugozi ubikwa muburyo buhujwe.② Dukurikije amabwiriza ya YDJ14-91, urwego rutagira ubushyuhe, urwego rwintwaro hamwe nimbaraga zishimangira umugozi wa optique rugomba guhagarikwa amashanyarazi, kandi ntiruhagarike, kandi rukaba rwarakingiwe hasi, rushobora kwirinda kwirundanya. yatewe numurabyo mumashanyarazi.Irashobora kwirinda ko umurabyo mwisi winjizwa mumurongo wa optique nigikoresho cyo hasi kubera itandukaniro muguhagarika inzitizi zumuriro wumuriro wumuriro hamwe nicyuma cyicyuma cya optique hasi.

Igipimo cya 2:
Kumugozi wo hejuru wa optique: insinga zo guhagarika hejuru zigomba guhuzwa namashanyarazi kandi zigashyirwa kuri 2km.Iyo ihagaze, irashobora guhagarikwa cyangwa guhagarikwa hifashishijwe igikoresho gikwiye cyo gukingira.Muri ubu buryo, insinga yo guhagarika ifite ingaruka zo gukingira insinga zo hejuru.

Igipimo cya 3:
Nyuma yaumugozi mwizayinjira muri terefone, agasanduku ka terminal kagomba kuba gahagaze.Nyuma yumurabyo winjiye mubyuma bya kabili ya optique, guhagarara kumasanduku ya terefone birashobora kurekura vuba umurabyo kandi bigira uruhare mukurinda.Umugozi wa optique ushyinguwe neza ufite urwego rwintwaro hamwe nimbaraga zishimangiwe, kandi icyuma cyo hanze ni icyatsi cya PE (polyethylene), gishobora gukumira neza kwangirika no kurumwa nimbeba.
