The Kramer 4K60 4:4:4 HDMI Extender Kit over Ultra-Reach MM/SM Fiber Optic is a high-performance HDMI fiber extender kit for ultra-reach extension of 4K at 60 Hz (4:4:4) HDMI signals. The 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. The 675R/T includes 2 multimode SFP+ transceivers, but can be used with any Kramer certified SFP+ transceiver, such as a single-mode SFP+ transceiver.
This high-performance standard fiber extender kit provides ultra-reach signals over either multimode or single-mode optical fiber infrastructures, using Kramer pluggable OSP SFP+ units. Near-zero latency video chroma subsampling conversion technology is employed to auto-adapt above 10G HDMI signals to 10G optical link signal data-rate. 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. Featuring I-EDIDPro Kramer Intelligent EDID Processing for intelligent EDID handling, processing and pass-through algorithm that ensures Plug and Play operation for HDMI source and display systems.
