ʻO OPGW (Optical Ground Wire) he ʻano uwea i hoʻohana ʻia ma ka ʻoihana kelepona e hoʻouna i ka ʻikepili ma o ka ʻenehana fiber optic, ʻoiai e hāʻawi pū ana i ka hoʻouna ʻana i ka mana uila ma nā laina uila uila kiʻekiʻe. Hoʻolālā ʻia nā kaula OPGW me kahi paipu waena a i ʻole ke kumu, a puni ia i hoʻomoe ʻia i hoʻokahi a ʻoi aʻe paha o nā uea kila a i ʻole aluminika, a me kahi papa waho o nā fiber optical. ʻO ke kūkulu ʻana i nā kaula OPGW e like me ka noi a me nā koi kikoʻī o ka ʻōnaehana laina mana.
ʻEkolu mau ʻano kumu o nā hale uwea OPGW:
Paipu Waena: ʻO kēia ʻano uwea he paipu waena, a puni nā uea kila a i ʻole nā uea alumini alumini. Hoʻokomo ʻia nā fiber optical i loko o ka paipu. Hāʻawi kēia hoʻolālā i ka maʻalahi o ka maʻalahi a hāʻawi i kahi ākea no nā fibers optical.
Pae ʻanuʻu: He mau papa kila a alumini paha kēia ʻano uwea i hoʻopaʻa ʻia. Hoʻokomo ʻia nā fiber optical ma waena o nā uea. Hāʻawi kēia hoʻolālā i ka ikaika a ʻoi aku ka kūpono no nā noi kiʻekiʻe.
Unitube: He paipu hoʻokahi kēia ʻano uwea kahi i waiho ʻia ai nā uwea kila a i ʻole aluminika a me nā fiber optical. Hāʻawi kēia hoʻolālā i kahi kaula paʻa i maʻalahi e hoʻokomo.
Hiki ke hoʻokaʻawale ʻia nā kaula OPGW ma muli o ko lākou helu fiber, mai 12 a 288 fibers. ʻO ke koho ʻana o ka helu fiber e pili ana i ka noi kikoʻī a me nā koi pono o ka ʻōnaehana laina mana.
