Monga ife tonse tikudziwa kuti mphezi ndi kutuluka kwa magetsi a mumlengalenga omwe amayamba chifukwa cha kumangidwa kwa ndalama zosiyana mkati mwa mtambo.Zotsatira zake ndi kutulutsa mphamvu kwadzidzidzi komwe kumapangitsa kuti pakhale kuwala kowoneka bwino, kutsatiridwa ndi kugunda kwa bingu.
Mwachitsanzo, sizidzangokhudza njira zonse za DWDM fiber mu kuphulika kwafupipafupi, komanso zimakhudza njira zotumizira nthawi imodzi malinga ndi kafukufuku wambiri.Zingayambitsenso moto pamene mphezi zikutuluka kwambiri.Ngakhale kuti zizindikiro mu zingwe za fiber ndi zizindikiro za kuwala, zingwe zambiri zakunja zogwiritsira ntchito zitsulo zolimbitsa thupi kapena zingwe zokhala ndi zida zowonongeka zimakhala zosavuta kuonongeka pansi pa mphezi chifukwa cha chitsulo choteteza mkati mwa chingwe.Choncho, ndikofunika kumanga njira yotetezera mphezi ku zingwe zotetezera zoteteza.

Kuteteza mphezi pamizere yowongoka ya chingwe chowongoka: ①Munjira yoyatsira muofesi, mbali zachitsulo mu chingwe cha kuwala ziyenera kulumikizidwa pamalumikizidwe, kuti pachimake cholimbitsa, chosanjikiza chinyontho ndi zida zankhondo za gawo lolumikizirana. chingwe amasungidwa mu chikhalidwe cholumikizidwa.②Malinga ndi malamulo a YDJ14-91, wosanjikiza wosanjikiza chinyezi, zida zankhondo ndi kulimbikitsa pakati pa chingwe cholumikizira ziyenera kulumikizidwa ndi magetsi, ndipo sizimakhazikika, zimayikidwa pansi, zomwe zingapewe kudzikundikira. kuchititsa mphezi mu chingwe cha kuwala.Zitha kupewedwa kuti mphezi yapadziko lapansi imalowetsedwa mu chingwe cha kuwala ndi chipangizo chokhazikika chifukwa cha kusiyana kwa kutsekeka kwa waya wachitetezo cha mphezi ndi chigawo chachitsulo cha chingwe chowunikira pansi.

Pazingwe zoyang'ana pamwamba: mawaya oyimitsidwa pamwamba ayenera kulumikizidwa ndi magetsi ndikukhazikika pa 2km iliyonse.Mukayika pansi, imatha kukhazikitsidwa mwachindunji kapena kukhazikitsidwa kudzera pa chipangizo choyenera choteteza maopaleshoni.Mwanjira iyi, waya woyimitsidwa amakhala ndi chitetezo cha waya wapansi pamtunda.

Pambuyo pakuwala chingweikalowa m'bokosi la terminal, bokosi la terminal liyenera kukhazikitsidwa.Pambuyo mphezi ikalowa muzitsulo zazitsulo za chingwe cha kuwala, pansi pa bokosi la terminal lingathe kumasula mphezi mwamsanga ndikugwira ntchito yoteteza.Chingwe choyang'ana mwachindunji chimakhala ndi zida zankhondo komanso pachimake chokhazikika, ndipo sheath yakunja ndi PE (polyethylene) sheath, yomwe imatha kuteteza dzimbiri ndi makoswe.
