| The OCA Series are professional quality, amplified output combiners. These units are designed for use in headends to combine and amplify the outputs of multiple modulators and processors. The OCA Series employs radiation-proof passive components that provide excellent signal reproduction and years of reliable service. Two models are available, including: OCA8b, 8 inputs; and OCA-12, 12 inputs.
The OCA Series features a single push-pull hybrid amplifier which supplies sufficient gain for driving a distribution system directly. The overall gain of the unit is variable using a built-in manual gain control, accessible via the front panel. The OCA Series provides high isolation between ports and net combining gain from each of the broadband inputs (50 to 450 MHz). A 20 dB test port is provided for signal monitoring without disrupting service.
