Opticis 19” 1U rack series is the ideal solution to mount multi-units of 3G-SDI extenders and supply power securely in various applications. Opticis BR-300 and BR-310, 19” 1RU frames are ideal solutions for modular and systematic fiber-optic needs adopting up to 12 units of 3G-SDI extenders securely in place. Each module slot is connected into a central power bus. Both two(2) power supply frames use 100-240VAC, 50-60Hz of input power, BR-300 for primary power and BR-310 for dual power with loadsharing and redundant backup. Its LEDs are indicated in the front panel for power supply failure. BR-300 and 310 use ST fiber connected on the front and SDI BNC connectors in the rear.
