673T, 673R - Getting Started

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.

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).
