2.1  
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.

Overview  
The 672T and 672R are an optical fiber transmitter and receiver for computer  
graphics signals up to UXGA and stereo audio signals. The 672T converts the  
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  
Full compatibility with the Kramer 670T/670R and 671T/671R HDMI/DVI  
transmitters and receivers for non-HDCP content  
5V DC power adapters  
Housing in Kramer DigiTOOLS® enclosures

Connecting the 672T, 672R  
Always switch off the power to each device before connecting it to your  
672T, 672R. After connecting your 672T, 672R, connect its power and  
i
then switch on the power to each device.  
Avoid direct eye exposure into the optic connectors when powered,  
although this product is regulated strictly enough to operate under the  
Laser Class 3R for eye safety  
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)).  
7. Connect the 5V DC power adapter to the power socket on each unit and  
connect the adapter to the mains electricity (not shown in Figure 3).  
Note: A 672T can be connected to Kramer’s 670R or 671R to convert a VGA input  
to an HDMI/DVI output.
