LA Techniques To Expand North America Presence

LA Techniques of Claygate in Surrey - a leading European supplier of low cost pattern generators for the fibre optic telecoms component industry - is to expand its activities throughout the United States and Canada.

2 DECEMBER 2002 - LA Techniques of Claygate in Surrey - a leading European supplier of low cost pattern generators for the fibre optic telecoms component industry - is to expand its activities throughout the United States and Canada.

The company, which has grown steadily over the last five years, has reached an agreement with Optimark Fiber Optics of Boston, Mass, which will involve the US partner in sales, distribution and acting as LA Techniques' representatives throughout North America.

"There has been a demand for our products in North America since we were formed - in fact our first export order was from the United States," explained LA Techniques' Sales and Marketing Director Chris Lester.

"We wanted to establish a more dedicated and thorough approach and we are absolutely delighted to have appointed Optimark, who have an outstanding reputation across the market place."

Among the products Optimark will be offering from LA Techniques will be the highly successful LA 19-02-01 12 Gb/s and the LA 19-01-01 2.7Gb/s pulse pattern generators. They will also be selling data driver amplifiers, other high speed logic circuits and bias tees.

The LA 19-02-01 is a pseudo random pulse pattern generator capable of operation of up to 12 Gb/s. It can accommodate two internal clock generators and also accepts an external clock input. It provides a fast pulse output up to 4 Vpp suitable for applications such as testing high bit rate communication components, fast pulse amplifiers and high speed logic circuit development. The LA 19-01-01 operates up to 2.7 Gb/s and provides a fast rise time and low pulse distortion. It can also accommodate two internal clock generators and an external clock output and provides a clean pulse output suitable for applications such as optical communications, fast pulse amplifiers and high speed logic circuit development.

Both products have established an international pedigree in production testing and development applications, where a fully-featured pattern generator is not always necessary.

LA Techniques will be exhibiting for the first time at OFC in March 2003, where it will be supported by Optimark.

"There is considerable life in the North American market, especially for high-spec, low-cost equipment that delivers on its promises," said Mr Lester.

"Our products have established that very reputation and I'm sure that by appointing Optimark as our representatives many more North American optical component companies will get an opportunity to find out for themselves".

LA Techniques Ltd develop and manufacture innovative products for broadband telecoms equipment by applying expertise in microwaves and rf to high-speed digital and analogue circuits, such as data driver amplifiers, pattern generators and pulse shaping circuits. It also offers consultancy in these related fields. Its headquarters is at Claygate near Esher in Surrey, where research and development and manufacturing is carried out.

Technical note to editors

The LA19-02-01 provides a binary sequence signal synchronised to either an internal or external clock. The sequences available are pseudo random (223-1 and 27), clock/2, clock/4, burst and a user-programmed 128 bit sequence. The 223-1 PRBS sequence is in accordance with the CCITT recommendation and the sequence is non-inverted. The 27 PRBS sequence is a zero substitution pattern where the longest run of zeros has been extended to eight zeros and the following bit set to one, thereby making the sequence 128 bits long.

The main output is ac-coupled and provides a user adjustable 2 to 4 Vpp signal with fast transitions of 35 ps. An internal bias-T is provided to allow a dc offset to be superimposed on the main data output. The bias-T supports a dc current of up to 100 mA. The waveform crossover can be adjusted over a range of +5% from the front panel. The auxiliary data output is a dc coupled, logic level output (0 to -0.8 V typical) with the same signal polarity as the main output.

Three types of synchronisation output signals are available, Clock, Clock/16, and Pattern. The clock is a sine wave with a typical amplitude of 0.8 Vpp. The clock/16 is derived from the clock signal by means of low noise dividers. The typical amplitude of this is 0.8 Vpp. The pattern synchronisation output produces an output synchronised to the length of the sequence selected. This allows, for example, the individual data bits to be observed on a sampling oscilloscope. It is available on all settings except the 223-1 pattern length setting.

A bias-T is included on the clock output. This allows a dc offset to be added to the ac clock signal. The maximum dc current allowed is 100 mA. Also, the clock output includes a mechanically adjustable phase shifter able to provide at least 540O of phase shift at 12 GHz.
