4-Channel 3G HD-SDI over Single Fiber Optic Transmitter & Receiver


FREE Shipping on orders over $100

The 673T and 673R are a high-performance fiber optic transmitter and receiver for video signals up to 3G HD-SDI and dual link HD-SDI signals. The 673T converts up to four channels of SDI signals on BNC connectors to an optical signal that is transmitted over a single fiber optic cable. The 673R converts the optical signal back to SDI signals.
