3 Overview
The 671T converts the DVI signal to an optical signal, and the 671R converts
the optical signal back into a DVI signal. Together, the 671T and 671R form a
DVI transmitter/receiver over multimode fiber system.
The 671T and 671R pair:
Features a transmission range of 2000 meters (more than 6560ft) over
multimode optical cable
Supports up to 1.65Gbps bandwidth per graphic channel1
Is strictly regulated in accordance with Class 3R Laser Eye Safety in
compliance with ANSI Z136 and IEC 60825-1:2007
Is HDCP compliant
Includes 5V DC power adapters and housing in Kramer DigiTOOLS®
enclosures
3.1 Recommendations for Achieving the Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position your
671T and 671R away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
