OPGW (Optical Ground Wire) ni ubwoko bw'insinga zikoreshwa mu nganda z'itumanaho mu kohereza amakuru binyuze mu ikoranabuhanga rya fibre optique, mu gihe kandi itanga amashanyarazi mu mashanyarazi menshi.Umugozi wa OPGW wakozwe hamwe numuyoboro wo hagati cyangwa intangiriro, uzengurutswe urwego rumwe cyangwa byinshi byuma cyangwa aluminiyumu, hamwe ninyuma ya fibre optique.Kubaka insinga za OPGW biratandukanye bitewe nibisabwa hamwe nibisabwa byihariye bya sisitemu y'umuriro.
Hariho ubwoko butatu bwibanze bwa kabili ya OPGW:
Tube Hagati: Ubu bwoko bwa kabili bugizwe numuyoboro wo hagati, uzengurutswe insinga z'ibyuma cyangwa insinga za aluminium.Fibre optique noneho ishyirwa mumiyoboro.Igishushanyo cyemerera guhinduka kwinshi kandi gitanga umwanya munini wa fibre optique.
Inzira: Ubu bwoko bwa kabili bufite ibyuma byinshi cyangwa insinga za aluminiyumu zifatanije hamwe.Fibre optique ishyirwa hagati yinsinga.Igishushanyo gitanga imbaraga nyinshi kandi kirakwiriye cyane murwego rwo hejuru.
Unitube: Ubu bwoko bwa kabili bufite umuyoboro umwe ushyizwemo insinga z'ibyuma cyangwa aluminiyumu hamwe na fibre optique.Igishushanyo gitanga umugozi woroshye byoroshye gushiraho.
Intsinga ya OPGW irashobora kandi gushyirwa mubikorwa ukurikije ibara rya fibre, iri hagati ya 12 na 288.Guhitamo fibre ibarwa biterwa na progaramu yihariye hamwe nubushobozi bukenewe bwa sisitemu y'umurongo w'amashanyarazi.
