PRECAUTIONS

1. Do not install the EHA-FTX/FRX near electric or magnetic fields.

Install the EHA-FTX/FRX away from TV/radio transmitters, magnets, electric motors,
transformers and audio speakers since the electromagnetic fields generated from these
devices may distort the video image.

2. Never disassemble the EHA-FTX/FRX beyond the recommendations in this manual
nor introduce materials other than those recommended herein.

Improper disassembly or introduction of corrosive materials may result in equipment

failure or other damage.

3. Keep the power cord away from water and other liquids and never touch the power

cord with wet hands.

Touching a wet power cord with hands or touching the power cord with wet hands may
result in electric shock.

4. Never install the EHA-FTX/FRX in areas exposed to water, oil or gas.

Water, oil or gas may result in equipment failure, electric shock or, in extreme cases, fire.

5. Do not operate the camera beyond the specified temperature, humidity or power

source ratings.

Use the camera at temperatures within 0℃ ~ 50℃ (32℉~122℉) and humidity between
20~80%. The input power source is 12VDC.

EHA-FTX

1. INTRODUCTION

The EHA-FTX / FRX are a pair of converters for transporting high definition digital video in

HD-SDI standards over fiber optics. The EHA-FTX modulates the HD-SDI video signal to be

transmitted over fiber optics, while EHA-FRX offloads the video signal at the receiving end and

converts it back to HD-SDI video compliant with SMPTE 292M, 296M standards, at data rates

up to 1.485Gb/s. With integrated cable equalizer technology, the EHA-FTX / FRX is capable of

transmitting and receiving HD-SDI digital video at up to 1920 x 1080 resolution over fiber optics

without loss of quality . This provides an effective solution for deploying HD-CCTV digital video

systems over large-span geographic areas.

2. FEATURES

 Support high-definition HD-SDI digital video at 720p60, 1080i60 and 1080p30 formats at

all frame rates

 HD-SDI standard at SMPTE 292M, 296M at 1.485Gb/s data rate
 Integrated cable equalizer for long distance video transmission without loss of quality
 Capable of transmitting and receiving HD-CCTV digital video over fiber optics
 High quality digital video transmission with near zero latency.

8. CABLE REQUIREMENTS FOR BNC CONNECTOR

8.1 Cable Types

Attenuation at 1 GHz: < 32 dB per 100m (328 feet)
Return Loss attenuation: > 20 dB
Impedance: 75 Ω

The table below gives an orientation for achievable cable distances:

Cable Type Attenuation in dB at 1

GHz per 100 m / 328 ft

RG-59 24 ~ 40 * 70 ~ 160 230~520

RG-6 15 ~ 35 * 100 ~ 190 330~620

RG-11, CATV-lowloss

cables

* Low quality cable may have higher attenuation

8 ~ 16 * 180 ~< 250 590~<820

Max. Cable distance in
m ft

8.2 Cable Installation

Please make sure, that the coaxial cable is not squeezed at any position.
Also the max. bending radius defined by the cable manufacturer should be considered.

General rule: maximum bending radius = 10 x outer cable diameter

Bending creates pressure on the center conductor, causing it to move through the dielectric

toward the inside of the bend. This affects impedance and return loss and reduces the
maximum possible cable length.

Please try to avoid any BNC - adapter or any connectors in the BNC cable.
Looping HD-SDI signals by BNC T-connectors to other devices is not possible.

8.3 BNC-plug

Also the BNC - plug plays an important role for clear HD-CCTV signal transmission.

Standard BNC plugs for CCTV have a quite high attenuation and may cause return losses due
to reflection effects.
We recommend using of HD-Video approved BNC plugs.
