Ellmax Electronics Ltd is a designer, manufacturer, and distributor of fibre-optics, electronics, and telecommunications training, test, and transmission 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, UWB, and OFDM. 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.
Emonaís netCIRCUITlabs digital and analog electronics circuit training product is supplied by Ellmax Electronics Ltd. These fully self-contained electronics labs trainers are based on real electronics circuits which can be accessed online via LAN or the internet by 25 or more students at the same time using a PC, laptop, or tablet using a web browser.† Each student can access and control any one of the multiple experiments on the plug-in applications board at any time, and there are built-in instruments including oscilloscope, spectrum analyser, cursor measurements, and full function signal generator.† Experiments include Basic Analogue and Op Amp circuit experiments and Combinational Logic experiments and cover AC amplifiers, feedback circuits, differential amplifiers, SCR circuits, OTL power amplifiers, op-amp circuits, waveform generators, resonant circuits & filters, digital logic gates, and combinational logic. The netCIRCUITlabs system enables students to get hands-on experience of electronics circuitry using actual hardware rather than a simulation.
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.
Ellmax Electronics Ltd supplies Ritelís comprehensive range of collet knobs, which are available in various sizes, designs, and colours, and come with full accessories. Short knobs, double knobs with coaxial collets, push-on knobs, soft-touch knobs, and 4mm terminals are also included in the range.† Download a short-form brochure on Ritelís products. An alternative short-form brochure with KX prefixed part numbers is also available, and this may be downloaded here.
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).
Products designed and manufactured by Ellmax Electronics Ltd are primarily in the area of fibre optics training, testing, and transmission for the educational, training, and industrial 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 ĶW 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 comprising a transmitter and a receiver for attenuation measurements, toning, and also voice communications, for testing and monitoring optical fibre, and which has SMA connectors as standard. It also incorporates a light to sound converter. 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).
