Getting Started

2.1 Quick Start

This quick start chart summarizes the basic setup and operation steps.

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 SCconnectors

•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-link1

•Are strictly regulated in accordance with Class 3R Laser Eye Safety in

compliance with ANSI Z136 and IEC 60825-1:2007

and support data rates

of 270Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps

•Feature HDTV compatibility

•Include cable equalization up to 350m for SD2signals, 140m for 1.5GHz

HD3

•Feature fiber optic, output and input indication LEDs

signals, and 120m for 3GHz HD signals

•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

adapter4

1 Using two BNC connectors per signal

2 Standard Definition (SD) means an NTSC or PAL compatible video format, consisting of 480 (for NTSC) or 576 (for PAL)

lines of interlaced video

3 High Definition (HD) means a video format, consisting of 720 active lines of progressive video or 1080 lines of progressive

or interlaced video

4 Up to three machines, side-by-side

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 noise-

levels (often associated with low quality cables)

•Avoid interference from neighboring electrical appliances and position your

673T and 673R 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 unit1

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.

5 Connecting the 673T and 673R Transmitter/Receiver System

To connect1the 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.

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 cabling2

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

(maximum

range of 900 meters (2950ft)).

Figure 3).

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
