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.

• High Performance Standard Fiber Extender - HDMI fiber transmitter for providing ultra-reach signals over either multi-mode or single-mode optical fiber infrastructures, using Kramer pluggable OSP SFP+ units (multi-mode SFP+ included). Near-zero latency video chroma sub-sampling conversion technology, is employed to auto-adapt above 10G HDMI signals to 10G optical link signal data-rate.
• Note: To ensure specified performance, support, and warranty of this product, use only Kramer's certified hi-performance OSP SFP+ pluggable optical units.
• Multi-drop Signal Distribution - Use optical splitters to extend the input signals from a single transmitter to multiple receivers, for displaying the same content on multiple display devices using optical splitting only, with no need for AV distribution amplifiers.
• HDMI Signal Extension - HDCP 2.2 compliant and supports up to 18G (6G per channel) data rate, LPCM 7.1, Dolby True HD, and DTS-HD as specified in HDMI 2.0.
• Power Saving - With CEC ON/OFF function, shut down a display device automatically when not in use, and auto power it ON upon presentation start.
• I-EDIDPro Kramer Intelligent EDID Processing - Intelligent EDID handling, processing and pass-through algorithm that ensures Plug and Play operation for HDMI source and display systems.
• Bidirectional RS-232 Extension - Serial interface data flows in both directions, to enable data transmission and control of devices.
• Cost-Effective Maintenance - Status LED indicators for power, source, sink and fiber link connections detection facilitate easy local troubleshooting.
• Easy Installation - DigiTOOLS rack mountable fan-less enclosure enables side-by-side mounting of 3 units in a 1U rack space with the recommended rack adapter.
