Ntchito yofunikira kwambiri pakupanga chingwe cha optical fiber ndikuteteza ulusi wa kuwala momwemo kuti ugwire ntchito motetezeka kwa nthawi yayitali m'malo ovuta.Zopangira zamagetsi zoperekedwa ndi GL Technology zimazindikira kutetezedwa kwa ulusi wowoneka bwino kudzera m'mapangidwe osamala, kuwongolera njira zapamwamba komanso kuwongolera zinthu mosamalitsa.Tiyeni tikambirane za kapangidwe kakeCHIKWANGWANI chamawonedwe chingwe.
Malinga ndi zotsatira za zolemba za kafukufuku wa ITU-T, chikhalidwe ichi chapanga chizoloŵezi chotsogola kwambiri padziko lonse lapansi, komanso ndi njira yomwe imakonda kwambiri mizere yamtunda wautali ku China.Kapangidwe kake ndikuyika ulusi wa kuwala mu chubu lotayirira ndikudzaza ndi mafuta a thixotropic osalowa madzi (mafuta odzola).Chubu lotayirira limapindidwa mozungulira pachimake cholimbikitsira chapakati kapena mawonekedwe a SZ kuti apange pakati pa chingwe.Malinga ndi ntchito zosiyanasiyana, m'chimake osiyana extruded kunja kwa chingwe pachimake, ndipo mipata pachimake chingwe amadzazidwa ndi mafuta (chingwe phala).mawonekedwe ndi:
1. Chimake cholimbikitsa chimakhala pakatikati pa chingwe chachitsulo, ndipo chubu lotayirira limakhala lopotoka pazitsulo zolimbitsa thupi ndi phula loyenera lopotoka.Pakuwongolera kutalika kopitilira muyeso wa ulusi wa kuwala ndikusintha mayendedwe okhotakhota, chingwe cha kuwala chimatha kukhala ndi zinthu zabwino zamakokedwe komanso mawonekedwe a kutentha.
2. Chitsulo chotayirira chokha chimakhala ndi mphamvu zambiri, ndipo chubucho chimadzazidwa ndi phala la fiber, lomwe limapereka chitetezo chofunika kwambiri cha fiber optical.Ulusi wa kuwala umayenda momasuka mu chubu ndipo umatetezedwa ku mphamvu zakunja
3. Chubu lotayirira ndi chitsulo cholimbitsa chimadzazidwa ndi phala la chingwe ndikupotoza pamodzi, kotero kuti kukhulupirika kwa chingwe chachitsulo kutetezedwa.
4. Kutsekemera kwamadzi ozungulira ndi kotalika kwa chingwe cha kuwala kumatsimikiziridwa ndi miyeso yotsatirayi: chingwe chimodzi chachitsulo chimagwiritsidwa ntchito m'malo mwa chingwe chachitsulo kuti chiteteze madzi kuti asalowe mumayendedwe aatali a chitsulo cholimbitsa;kudzazidwa kwa phala la chingwe kumatsimikizira kutetezedwa kwamadzi kwakutali kwa dera la triangular pakati pa waya wachitsulo ndi casing;Phala la CHIKWANGWANI lingalepheretse chinyontho kuwononga ulusi wa kuwala;phala la chingwe limadzazidwa ndi kukakamizidwa kuti zitsimikizire kuti chingwe chachitsulo chadzaza kwathunthu;tepi ya aluminiyamu yokutidwa ndi pulasitiki ndi zida zachitsulo zamalata zimamangiriridwa motalika ndi zomatira zosungunuka kutentha kuti mamolekyu amadzi ozungulira asalowemo;zida zosanjikiza ulusi wotchinga madzi umagwiritsidwa ntchito ndi sheath yamkati kuti zitsimikizire kuti chingwecho chimagwira ntchito motalikirapo komanso kuti chingwecho chikhale cholimba.
