FT120AB Series Installation & Operation Manual

(1) Safety Instructions

Please be familiar with all information in this manual prior to installation and
operation.

Note 1: The products described contain a Class 1 laser or LED fiber optic emitter. The following

safety precautions apply.

Warning: Do not disconnect the fiber optic connector while the unit is powered up.
Exposure to Class I invisible optical radiation is possible when the internal fiber optic
connector is disconnected while the unit is powered up.

Caution: Any access to the controls, adjustments, or performing operations, which are
other than those specified may result in hazardous radiation exposure. Permanent eye
damage or other bodily injuries may be resulted from such exposure even for only
seconds.

Note 2: This assembly contains parts sensitive to damage by electrostatic discharge (ESD). ESD
precautionary procedures should be applied in the course of touching, removing or inserting parts
or assemblies.

FT120AB Series Installation & Operation Manual

(2) Product Overview

2.1 Introduction

The FT120AB Series products comprise of either single-mode or multi-mode fiber optic
transmitters and receivers for the optical transmission of ONE forward (Tx → Rx) video and TWO
duplex (Tx ↔ Rx) audio signal on one fiber. The products work at wavelengths of 1310nm and
1550nm with either a 9/125um or 62.5/125um fiber for single-mode or multi-mode transmission
respectively.

A non-compressed 10-bit digital video transmission scheme is implemented which supports
video in NTSC, PAL and SECAM formats.

A 24-bit digital PCM transmission scheme is employed for analogue audio transmission.
Both balanced and unbalanced audio inputs and outputs are supported. Optical Wavelength
Division Multiplex (WDM) technique is also employed for simultaneous reverse audio signal
transmission.

For single-mode transmission, we also offer specifically designed products for long-haul
transmissions up to 60km. These models include the letter “L” in the suffix, e.g. FT120AB-SSTL
for Tx, FT120AB-SSRL for Rx, etc.

The FT120AB Series units are available as standalone units, which can be mounted
horizontally or vertically wall-mounted on any fixture. The standalone unit comes with an external
power supply FT-PA/12V, which can be powered by local 110/220V power.

The FT120AB Series units are also available as plug-in card modules installed in a 19”
rack-mount chassis. Each plug-in card occupies two slots in the rack-mount chassis. The rack
mount chassis has to be ordered separately, and comes with its own power supply for powering
the installed card modules.
