General Specifications
The ADSL micro filter has been specifically designed to implement the functionality of lowpass filter of POTS splitter in ADSL application. This filter protect POTS from interference signal produced by transceiver and also protect transceiver from all POTS related signals where as it do not provide surge voltage protection. It contain a plastic enclosure including RJ11 socket at either end.
Feature
- Consist exclusively of passive element.
- Handle all POTS loop currents from 0mA to 100mA.
- Designed for implementation of ADSL CPE application.
- Provides excellent isolation between ADSL and POTS.
