ELLMAX ELECTRONICS LTD
FIBRE-OPTICS
AND TELECOMMUNICATIONS
Ellmax Electronics Ltd is a designer, manufacturer, and distributor 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, OQPSK, and UWB. 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 ETT-101 (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 ETT-202, 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, 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.
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) HUXCleaner 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).
The full range of fibre-optics analogue and digital telecommunications systems covering video, audio, and data from OPTICOMM CORPORATION is supplied by Ellmax Electronics Ltd. This range covers the areas of High Resolution VGA/RGB video (with data and audio), DVI, USB, CCTV (with data and audio), SDI, HD-SDI, DVB-ASI, AES/EBU, CATV (RF & L-Band), and datacommunications. A single fibre system is available for transmitting VGA/RGB video as well as stereo audio channels, keyboard and mouse data, and RS232. The datacommunications products include 10Mb/s, 100Mb/s, and 1Gb/s Ethernet systems, a Fast Ethernet Media Converter, Ring/Bus Topology modules, RS-232, RS-422, RS-449, RS-485, RS-530, Contact Closure, TTL, T1, E1, T3, E3 transmission devices, and various multiplexers. TDM, FDM, and WDM systems are available for transmitting several simplex or duplex signals down a single fibre. A versatile high-speed 144 port optical switch is also available. All OPTICOMM's products come with a 10 year warranty and are manufactured to a near military specification.
A comprehensive range of fibre-optics test equipment manufactured by Tempo is supplied by Ellmax Electronics Ltd. This range includes power meters, LED and laser sources, return loss test sets, high resolution OTDRS, variable attenuators, laser fault finders, and bare fibre adaptors.
Ellmax Electronics Ltd is a supplier to schools of Roberts Radios, particularly the Roberts R9966 Rugged Radio. This Radio/Audio Amplifier is ideally suited for schools, both for general use and in science departments. It features a powerful 7W output with a 160mm loudspeaker, has excellent sound quality, is housed in a robust and water resistant casing, and is mains or battery operated. It contains sockets for a microphone, an auxiliary input, and headphones. So, as well as being used as a radio, the unit may be used as a portable public address system or general sound/music amplification system when a microphone is attached, a variable gain audio amplifier (with or without loudspeaker output), and also an audio signal source. Optional accessories are a high quality dynamic microphone with metal housing and a set of 6 alkaline batteries. Ex VAT prices are £85.00 for the R9966 radio/audio amplifier, £12.50 for the dynamic microphone, £7.50 for the set of 6 type D alkaline batteries, and £10.00 for carriage in the UK.
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, a highly versatile and self-contained product for demonstrating the principles and applications of fibre-optics communications, 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.
FIBRE-OPTICS POWER METER, which is an analogue (analog) meter showing both dBm and µW on the same scale.
FIBRE-OPTICS MONITOR, a low-cost measuring test set for attenuation measurements, toning, and also voice communications.
FIBRE-OPTICS TRAINER, a low-cost product for secondary schools that is
designed for teaching the principles and applications of fibre-optics
communications and analogue (analog) and digital techniques. This
product, which includes two red LED sources and incorporates plastic fibre, can
show free-space transmission and may also be used in various light and optics
experiments.
