Kramer 4K60 4:4:4 HDMI and RS–232 Receiver over Ultra–Reach MM/SM Fiber Optic

676R is a high−performance HDMI fiber receiver for ultra−reach extension of 4K@60Hz (4:4:4) HDMI signals.

676R receives the transmitted optical signal from a compatible transmitter and converts it to an HDMI and RS−232 signals.

676R includes a multimode 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 receiver for providing ultra–reach signals over either multimode or single-mode optical fiber infrastructures, using Kramer pluggable OSP SFP+ units (multi-mode SFP+ included).

Near-zero latency video chroma subsampling 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.
