The 2-way Coaxial Semi-isolated Isolator Single Galvanized F-F F-F Data TV 5-862MHz from Technetix is a Coaxial Galvanic Isolator. Coaxial isolator is a two-port passive device used for isolation a circuit from a source of power, it protects other components from excessive signal reflections. Usually, isolator is called unline, because it absorbs the power for propagation in one direction and provides lossless transmission in the opposite direction.
Isolators (frequently referred to as system outlets) are used to separate the in-home installation or subscriber equipment from the CATV network. They prevent hazardous voltages from being transferred to in-home installations. Technetix supplies two major types of isolator; fully and semi-isolated system outlets. The TSA-series consists of semi-isolated system outlets. This type of isolator incorporates an isolating component (high voltage capacitor) in series with the inner conductor of the coaxial connectors. The TSA-series has been specially developed to meet the needs of the European market. There are a variety of single, dual and three port isolators in the TSA series. Additional circuits are incorporated into some designs. Tap outputs, filters and splitter circuits are available.
TSA semi-isolated system outlets have a silver plated, zinc die-cast housing. The inner spring of the connector has been designed to accept coax cables with an inner conductor of between 0.51 and 1.20 mm. It retains this elasticity and provides effective clamping force even when varying thicknesses of inner conductor are connected in succession. The high frequency shielding exceeds Class A requirements (IEC-60728-2) over the frequency range.
