converts the optical signal back into an HDMI signal. Together, the 670T and
670R form an HDMI transmitter/receiver over multimode fiber system.
The 670T and 670R pair:
Features a transmission range of 1700 meters (more than 5570ft)
over an optical cable
Is strictly regulated in accordance with Class 3R Laser Eye Safety in
compliance with ANSI Z136 and IEC 60825-1:2007
Includes HDMI connectors
Transmits four TMDS video channels as well as one low-speed
channel for passing HDCP, EDID, 5V source and a Hot Plug Detect
(HPD) signal over one multimode fiber
Supports up to 2.25Gbps bandwidth per graphic channel1

Has 5V DC power adapters and is housed in Kramer DigiTOOLS®
enclosures
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital2
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
In particular, HDMI3:
Provides a simple4 interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and video monitor, such as a
digital flat LCD / plasma television (DTV), over a single lengthy5 cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio6 on a single cable
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digitalto-analog conversions
3 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
licensing LLC
4 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
6 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
4
Transmits all ATSC HDTV standards and supports 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements and
requirements
Benefits consumers by providing superior, uncompressed digital video
quality via a single cable1, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support:
Existing high-definition video formats (720p, 1080i, and 1080p/60), as
well as standard definition formats such as NTSC or PAL
3.2 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 noise-levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position
your 670T and 670R 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 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner
