Kramer 675R/T (50-00016090)

The Kramer 675R/T is a high-performance HDMI fiber extender kit for ultra-reach extension of 4K@60Hz (4:4:4) HDMI signals. 675T converts the HDMI input signal to an optical signal that is transmitted over a fiber optic cable to 675R, which converts it back to an HDMI signal. 675R/T includes 2 multi-mode SFP+ transceivers, but can be used with any Kramer certified SFP+ transceiver, such as a single-mode SFP+ transceiver.

  • High Performance Standard Fiber Extender Kit — Provides ultra–reach signals over either multi–mode or single–mode optical fiber infrastructures, using Kramer pluggable OSP SFP+ units. 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.
