Nta
- Raws li tus kheej-copyright IC
- Modular wide dynamic optical ntes
- Siv tus qauv 2 xov tooj xov tooj (tsis yog xov tooj tuav) teeb tsa raws li kev txiav txim hluav taws xob-xaim xov tooj (yeem)
- E1 interface ua raws li G.703, txais yuav cov moos digital rov qab thiab du theem-xauv tshuab
- Thaum cov teeb liab kho qhov muag poob, nws tuaj yeem ntes cov khoom siv tej thaj chaw deb yog hluav taws xob lossis fiber ntau raug txiav, thiab qhia lub tswb los ntawm LED
- Cov cuab yeej hauv zos tuaj yeem saib cov cuab yeej ua haujlwm nyob deb
- Muab cov lus txib rau tej thaj chaw deb interface Loop Back, yooj yim kho kab
- Qhov kis tau tus mob mus txog 2-120Km yam tsis muaj kev cuam tshuam
- AC 220V, DC-48V, DC + 24V tuaj yeem xaiv tau
- DC-48V / DC + 24V fais fab mov nrog tsis siv neeg polarity nrhiav muaj nuj nqi, thaum ntsia tsis muaj qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo
