ELLMAX
ELECTRONICS 
LTD
FIBRE-OPTICS
AND TELECOMMUNICATIONS
Ellmax Electronics Ltd is a designer, manufacturer,
and distributor primarily of fibre-optics and telecommunications equipment.
Ellmax Electronics Ltd supplies the TIMS telecommunications
training system which is designed for university level
telecommunications and signal processing courses. TIMS, which is manufactured
by Emona Instruments Pty Ltd., is a modular,
expandable hardware system covering the vast majority of analogue and digital
modulation and coding techniques, from the basic schemes to advanced concepts
such as Convolutional Coding and Decoding, Trellis
Coded Modulation and Demodulation, CDMA Encoding and Decoding, Frequency Hop
Spread Spectrum, DSP, MSK, OQPSK, and UWB. A stand-alone DSP development and
training system, the TIMS-DSP-6713, is also available. The TIMS range includes
a software simulation package and a version of the TIMS hardware which is
accessible over the web.
A lower-cost hardware product, the ETT-101 Telecoms-Trainer,
also manufactured by Emona Instruments, is also
available. The ETT101 (known as biskitTM) is a single board trainer,
and covers a broad range of analogue and digital experiments, including all the
basic modulation schemes, and also includes sampling, PCM encoding and
decoding, line coding, data recovery in a noisy channel, eye patterns, QAM,
BPSK, DPSK, QPSK, and frequency synthesis. Add-on Experiment Boards and an
Electronic Circuits Project Board are also available for the ETT-101.
Another product in the range, the ETT-202
DATExTM Telecoms-Trainer, is a
multi-experiment single board trainer designed for the NI ELVISTM platform
and which can also operate under NI LABVIEWTM software. The ETT202,
which is controlled by either front panel knobs and
switches or through the computer via a Soft Front Panel (SFP), enables an
extensive range of analogue and digital experiments to be carried out.
Ellmax Electronics Ltd supplies a range of HU-125 Bare Fiber
Alignment Modules. These HU125 devices, also known as
Multipurpose Pigtails, are used for making OTDR and other measurements on singlemode or multimode bare fibres in development,
production, and installation environments. Losses of these bare fiber adapters are below 0.3dB. Options include HU-125-SM singlemode, HU-125-MM multimode (62.5/125 or 50/125 cable),
FC, SC, or ST connectors, PC or APC, standard cable length of 1.4 metres or
optional cable length of 3 metres. These HU125SM and HU125MM bare fibre
alignment modules or bare fibre adaptors are long-lasting and easy-to-use
alternatives to elastomeric splices. Download and print a datasheet on the HU 125 Bare
Fibre Alignment Modules.
HUXCleaners, which are pen-type units for cleaning ferrules housed in an adaptor, are supplied by Ellmax Electronics Ltd. Both 2.5mm (for SC, FC, ST) and 1.25mm (for LC, MU) HUX Cleaner units are available, and each provides over 500 cleans. The HUXCleaner is a very effective, simple-to-use, cost-effective, and convenient tool for in-adaptor ferrule cleaning (without having to remove the connector from the adapter).
FIBER OPTIC TRAINING EQUIPMENT
Products designed and manufactured by Ellmax
Electronics Ltd are primarily in the area of fibre optics training for the
educational and training markets worldwide, and include:
FIBRE-OPTICS
EDUCATOR (also known as EFO1101 or KOP101), a highly versatile and
self-contained product for demonstrating the principles and applications of
fibre-optics communications and general telecommunications, covering analogue (analog) and digital transmission and also attenuation
measurement methods. The
product includes both red and infra-red sources, incorporates plastic fibre,
and shows free-space transmission as well as communications over optical cable.
A comprehensive 40-page instruction manual is included (see below for viewing
or downloading a cut-down version of this manual). Download and print a 4
page datasheet on the Fiber Optics Educator (EFO 1101
or KOP 101).
FIBRE-OPTICS POWER METER
(also known as EFO1102 or KOP106), which is an analogue (analog)
meter showing both dBm and µW on the same scale, and
has an SMA connector as standard. A detailed instruction manual is included (see
below for viewing or downloading). Download and print a 2 page
datasheet on the Fiber Optics Power Meter (EFO 1102
or KOP 106).
FIBRE-OPTICS MONITOR (also known as
EFO1105 or KOP105), a portable test set for attenuation measurements,
toning, and also voice communications, for testing multimode fibre, and which
has an SMA connector as standard. A detailed instruction manual is included
(see below for viewing or downloading). Download and print a 4 page
datasheet on the Fiber Optics Monitor (EFO 1105 or
KOP 105).
FIBRE-OPTICS
TRAINER (also known as KOP103), a low-cost product for secondary
schools that is designed for teaching the principles and applications of
fibre-optics communications, general telecommunications, and analogue (analog) and digital techniques. This open-PCB based product, which includes two
red LED sources and incorporates plastic fibre, can show free-space
transmission as well as communications over optical cable, and may also be used
in various light and optics experiments. A comprehensive 34-page instruction
manual is included (see below for viewing or downloading a cut-down version of
this manual). Download and print a 2 page
datasheet on the Fiber Optics Trainer (KOP 103).
A higher bandwidth version of the
Fibre-Optics Trainer is available for optical transmission applications using
visible light over plastic fiber or free-space
requiring an analogue (analog) bandwidth of up to 300
kHz or a digital bandwidth of up to 500 kBit/s. Download
and print a spec sheet of the Fibre-Optics Trainer Higher Bandwidth Option.
