The DFT-16 can handle up to 16 channels of 3G/HD-SDI, ASI or MADI in just one RU and over just one single-mode fiber. The direction of the signal paths are user-configurable in pairs of two in order to meet any send/receive requirements, and redundant power supplies are standard for ensuring a complete backup of critical paths. In addition, full-fiber redundancy with automatic fail-safe switchover is available as an option for all DFT Series frames.
