2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
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 673T, 673R 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.

2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country

673T, 673R - Overview
3 Overview
The 673T is a high-performance fiber optic transmitter for 3G HD-SDI, HD-SDI,
SDI, and dual-link SDI signals. The unit converts up to four channels of serial
digital signals on gold-plated BNC connectors to light pulses that are transmitted
over a single multimode fiber optic cable to a 673R receiver that converts them
back to serial digital signals. The 673T and 673R pair has a transmission range of
1000 meters (more than 3,200ft).
Both the 673T and 673R:
Feature a maximum data rate of up to 3Gbps, enabling it to be used for
standard definition, high definition and the new 3G high definition serial
digital video signals (SD/HD-SDI)
Feature a single multimode OM3 fiber optic with SC connectors
Include four HD-SDI signals on gold-plated BNC connectors each for the
transmitter and the receiver
Support SDI, HD-SDI, 3G HD-SDI and dual-link and support data rates of
270Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps
Are strictly regulated in accordance with Class 3R Laser Eye Safety in
compliance with ANSI Z136 and IEC 60825-1:2007
Feature HDTV compatibility
Include cable equalization up to 350m for SD signals, 140m for 1.5GHz HD
signals, and 120m for 3GHz HD signals
Standard Definition (SD) means an NTSC or PAL compatible video format, consisting of
480 (for NTSC) or 576 (for PAL) lines of interlaced video. High Definition (HD) means a
video format, consisting of 720 active lines of progressive video or 1080 lines of
progressive or interlaced video
Feature fiber optic, output and input indication LEDs
Include reclocking and equalization on each channel
Include 5V DC power adapters and housing in Kramer DigiTOOLS®
enclosures
Can be rack mounted in a 1U rack space with the optional RK-3T rack
adapter

4 Connecting the 673T, 673R
Always switch off the power to each device before connecting it to
your 673T, 673R. After connecting your 673T, 673R, connect its
power and then switch on the power to each device.
Warning:
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 673T and 673R, as illustrated in the example in Figure 3, do the
following:
1. Connect up to four SDI sources (for example video players and/or HD-SDI
cameras) to the four SDI IN connectors.
You do not have to connect all the inputs and outputs.
2. Connect the four SDI OUT connectors to up to four SDI acceptors (for
example, HD-SDI displays).
3. Remove the dust caps and connect the OPTIC CABLE connector of the
673T to the OPTIC CABLE connector of the 673R, via OM3 cabling with SC
connectors (maximum range of 900 meters (2950ft)).
4. 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).
