G.657A1 Faeba e kobehang ea mofuta o le mong Fiber e Hlahetsoeng

Tlhaloso e Khutšoanyane:

Sehlahisoa se amohela theknoloji e tsoetseng pele ea ho etsa li-fiber e entsoeng ka pele, e ka laolang OH- content ea fiber prefabricated rod ho ea boemong bo tlaase haholo, kahoo sehlahisoa se na le coefficient e babatsehang ea ho fokotsa metsi le tlhōrō e tlaase ea metsi, ts'ebetso e babatsehang ea phetisetso. Sehlahisoa se ka etsa bonnete ba hore sebaka se senyenyane sa ho koba ha se ntse se lumellana ka ho feletseng le marang-rang a G.652D, kahoo fiber e ka finyella ka botlalo litlhoko tsa wiring tsa FTTH.

Likarolo tsa Sehlahisoa

● Excellent attenuation coefficient le tlaase metsi tlhoro.

● "O - E - S - C - L bakeng sa phetiso eohle ea lihlopha.

● Tahlehelo e tlaase ea ho kobeha.

Tlhahiso ea Sehlahisoa

Sesebelisoa sa Sehlahisoa

1. E loketse mefuta eohle ea sebopeho sa thapo ea fiber optic: mofuta oa li-tube tse bohareng, mofuta o hlephileng oa lera, mofuta oa skeleton, sebopeho sa mohala oa fiber optic;

2. Likopo tsa fiber optics li kenyelletsa: lisebelisoa tsa fiber optic tse hlokang tahlehelo e tlaase le bandwidth e phahameng; E loketse ka ho khetheha bakeng sa MAN e bonolo ea optical cable, sesebelisoa se senyenyane sa optical fiber, optical fiber coupler le lisebelisoa tse ling tse khethehileng;

3. Mofuta ona oa fiber o loketse lihlopha tsa O, E, S, C le L (ke hore, ho tloha 1260 ho ea ho 1625nm). Mofuta ona oa fiber optical o lumellana ka botlalo le fiber ea G.652D. Litlhaloso tsa tahlehelo ea ho kobeha le sebaka se kopaneng li ntlafatsoa haholo, ka bobeli ho ntlafatsa khokahano;

4. E ka tšehetsa ho kenngoa ha litsamaiso tse nyenyane tsa halofo-diameter le tse nyenyane tsa optical fiber liteishene tsa liofisi tsa puisano le libaka tsa bareki mehahong ea bolulo le matlong a batho ka bomong.
