Dome type fiber optical splice closures (FOSC) adapangidwa kuti azigwiritsidwa ntchito panjira zapakati pa loop ndi chingwe cha mailosi omaliza pakumanga ma fiber optical network. Zina zomwe zimatchedwa bunchy FOSC ndizothandiza kuphatikiza ma fiber cores ndi fusion splicer ndi machubu achitsulo otentha. Nthawi zambiri amalumikizidwa pamutu, popanda kutha kwa chingwe chachikulu.
FOSC imapereka chitetezo chodalirika komanso nthawi yayitali yogwiritsira ntchito poyerekeza ndi mabokosi ochotsa fiber optic a chingwe chapakati cha loop feeding, kuti alumikizitse ndi zingwe zazing'ono muukadaulo wa FTTx womanga intaneti.
Izi zimayendetsedwa ndi kutentha shring mfundo protechtion ndi mpweya utsi. Takulandirani kuti mutithandize kudziwa zambiri.
