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, non-expandable 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.
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.
