One of the largest challenge at building a headend is to realize a clear-cut and small sized RF connection network between the signal sources and the optical elements. COMTECH provides 1U sized active and passive signal organizers containing splitters, combiners and direction couplers with various coupling values optimized for optical or coaxial segments. As special products bandpassed and impedance matching types are developed too. For feeding this network high level amplifiers may be needed which are available in forward path and in return path. The amplifiers are insertable into the optical mainframes and can be managed by all COMTECH monitoring solutions.
