OPGW (Optical Ground Wire) ke mofuta oa thapo e sebelisoang indastering ea likhokahano ho fetisa data ka theknoloji ea fiber optic, ha e ntse e fana ka phetiso ea matla a motlakase methapong ea matla a phahameng a matla a holimo. Lithapo tsa OPGW li entsoe ka phaephe e bohareng kapa konokono, eo ho pota-potileng eona ho behiloeng lera le le leng kapa ho feta tsa tšepe kapa lithapo tsa aluminium, le lera le kantle la likhoele tsa optical. Kaho ea likhoele tsa OPGW e fapana ho latela ts'ebeliso le litlhoko tse ikhethileng tsa sistimi ea mohala oa motlakase.
Ho na le mefuta e meraro ea mantlha ea meaho ea cable ea OPGW:
Central Tube: Mofuta ona oa mohala o na le tube e bohareng, eo ho eona ho nang le lithapo tsa tšepe tse behiloeng kapa lithapo tsa alloy aluminium. Joale likhoele tsa optical li behoa ka har'a tube. Moqapi ona o lumella ho fetoha ha maemo le ho fana ka sebaka se eketsehileng bakeng sa likhoele tsa optical.
Lera Stranding: Mofuta ona oa mohala o na le likarolo tse 'maloa tsa lithapo tsa tšepe kapa tsa aluminium tse hokelletsoeng hammoho. Likhoele tsa optical li behiloe ka har'a li-interstices pakeng tsa likhoele. Moqapi ona o fana ka matla a eketsehileng 'me o loketse haholoanyane likopo tse phahameng tsa tsitsipano.
Unitube: Mofuta ona oa mohala o na le tube e le 'ngoe eo ho eona ho behoang lithapo tsa tšepe kapa tsa aluminium le likhoele tsa optical. Moralo ona o fana ka thapo e kopaneng eo ho leng bonolo ho e kenya.
Lithapo tsa OPGW le tsona li ka hlophisoa ho latela palo ea tsona ea fiber, e tlohang ho 12 ho isa ho 288 fibers. Khetho ea palo ea fiber e itšetlehile ka ts'ebeliso e khethehileng le litlhoko tsa bokhoni ba tsamaiso ea lithapo tsa motlakase.
