Awoṣe pato:Okun-ipo kanṣoṣo ti ko ni itara (G.657A2)
Iwọn alaṣẹ:Pade awọn ibeere ti ITU-T G.657.A1/A2/B2 opitika fiber imọ ni pato.
Awọn ẹya ara ẹrọ ọja:
- Radiọsi atunse to kere julọ le de ọdọ 7.5mm, pẹlu resistance atunse to dara julọ;
- Ni ibamu ni kikun pẹlu G.652 okun ipo-ọkan;
- 1260 ~ 1626nm ni kikun igbi okun gbigbe;
- Pipin ipo polarization kekere pade awọn iwulo ti iyara giga ati gbigbe gigun;
- Ti a lo ni ọpọlọpọ awọn kebulu opiti, pẹlu awọn kebulu opiti tẹẹrẹ, pẹlu iwọn kekere afikun attenuation ti atunse bulọọgi;
- O ni awọn paramita egboogi-irẹwẹsi giga lati rii daju igbesi aye iṣẹ labẹ radius atunse kekere.
- Akiyesi Ohun elo: O ti lo si awọn kebulu opiti ti awọn oriṣiriṣi awọn ẹya, gbigbe gigun ni kikun ni 1260 ~ 1626nm, FTTH ipa ọna opopona iyara-giga, awọn kebulu opiti pẹlu awọn ibeere radius atunse kekere, awọn kebulu opiti kekere ati awọn ẹrọ okun opiti, ati awọn ibeere ti lilo L-iye.
