676T is a high-performance HDMI fiber transmitter for ultra-reach extension of 4K@60Hz (4:4:4) HDMI signals. 676T converts the HDMI and RS-232 input signal to an optical signal that is transmitted over a fiber optic cable to a compatible receiver that converts it back to HDMI and RS-232 signals. 676T includes a multi-mode SFP+ transceiver, but can be used with any Kramer certified SFP+ transceiver, such as a single-mode SFP+ transceiver.
