Alkalmazás

Earthing is available in a number of combinations to suit most applications. As standard, a capacitor is arranged to connect the grounding of the co-axial to twisted pair and a zero ohm resistor ties the grounding of both coaxial connectors.

Dual Balun

This module contains 2 Coaxial Connectors, 2 Baluns and 1 RJ45 socket housed in an insulated enclosure. It is intended to convert an E1/T1 Channel consisting of 1 Transmit and 1 Receive signal from 75Ω coaxial to 2 x 120Ω twisted pair signals on an RJ45/Cat5 cable.

High Speed Dual Balun 34 to 155Mbit/s

This module offers two STM1 155Mbit/s paths (also 140Mbit/s, 45Mbit/s or 34Mbit/s) into a single RJ45 socket from coaxial feeders. The module contains 2 Coaxial Connectors, 2 Baluns and 1 RJ45 socket housed in an insulated enclosure.
