Telecommunication and Data Line Filter (TDLF) is a Front-End device for use in communication system. The device collects more than 200 signals such as Fast Ethernet (1Gbit), RS422, RS232, Video, discrete etc, and provides full guaranty for Signal Integrity (SI). It is used in all air, naval and ground platforms.The unit is plugged in to a communication cabinet.
It has the capabilities of:
- Protection against lightning.
- Protection against other spikes and surges.
- Full RFI, EMI immunity for the equipment within the shelter.
