Tlhaloso ea mohlala:faeba ya mofuta o le mong e sa utlweng (G.657A2)
Tekanyetso ea tsamaiso:Kopana le litlhoko tsa ITU-T G.657.A1/A2/B2 lintlha tsa tekheniki tsa fiber optical.
Likarolo tsa sehlahisoa:
- Sebaka se fokolang sa ho kobeha se ka fihla ho 7.5mm, ka khanyetso e ntle ea ho koba;
- E lumellana ka botlalo le G.652 fiber ea mofuta o le mong;
- 1260～1626nm phetiso e felletseng ea waveband;
- Phatlalatso e tlase ea mokhoa oa polarization e kopana le litlhoko tsa phetisetso ea lebelo le phahameng le sebaka se selelele;
- E sebelisoa likhoeleng tse fapaneng tsa optical, ho kenyeletsoa likhoele tsa ribone tsa optical, tse nang le attenuation e tlase haholo ea "micro-bending";
- E na le li-parameter tse phahameng tse thibelang mokhathala ho netefatsa bophelo ba ts'ebeletso tlas'a radius e nyenyane ea ho kobeha.
- Tlhokomeliso ea Kopo: E sebelisoa ho likhoele tsa optical tsa meaho e fapaneng, phetiso ea maqhubu a felletseng ho 1260 ~ 1626nm, FTTH ea lebelo le phahameng la optical routing, likhoele tsa optical tse nang le litlhoko tse nyane tse kobehang, likhoele tsa boholo bo nyane le lisebelisoa tsa optical fiber, le litlhoko. ea ho sebelisa L-band.
