Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer 672T, 672R away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

computer graphics and stereo audio signals to an optical signal, and the 672R
converts the optical signal back to computer graphics and stereo audio signals.
Together, the 672T and 672R form a UXGA/audio transmitter/receiver over
multimode fiber system.
The 672T and 672R pair features:
A transmission range exceeding 1700 meters (more than 1 mile) over
multimode optical cable
4.95Gbps (1.65Gbps per graphic channel) suitable for resolutions up to
UXGA at 60Hz, and for all HD resolutions
Regulation in accordance with Class 3R Laser Eye Safety in compliance with
ANSI Z136 and IEC 60825-1:2007

To connect the 672T and 672R, do the following:
1. Connect a computer graphics source (for example, a computer graphics card on
a PC) to the UXGA IN 15-pin HD connector.
2. Connect a stereo audio source (for example, a stereo audio player) to the
AUDIO IN 3.5mm mini jack connector.
3. Connect the UXGA OUT 15-pin HD connector to a computer graphics acceptor
(for example, an LCD display).
4. Connect the AUDIO OUT 3.5mm mini jack connector to a stereo audio acceptor
(for example, the speakers of an LCD display).
5. On the 672R, set the SOURCE switch to VGA. (If a Kramer 670T or 671T
transmitter is connected to the 672R, set the SOURCE switch to HDMI).
6. Remove the dust caps and connect the OPTIC CABLE connector of the 672T to
the OPTIC CABLE connector of the 672R, via OM3 cabling (maximum range of
1700 meters (over 1 mile)).
