Designed at Nortel optical lab at 3500 Carling Ave., Ottawa, in the early 1990s. Nortel was the first optical equipment vendor to introduce optical transmitters and receivers able to operate at 10 Gbps, the OC 192 industry standard for fibre optic networks. As a result, Nortel enjoyed market dominance in these products for the rest of the decade. Later versions were used extensively in metropolitan (metro) fibre optic networks.

Function

A device used to provide and modulate a laser light source for a fibre optic network.

Technical

This is a 10 Gbps transmitter designed for the OC192 optical network standard. It has a range of 80-170km without regeneration. Known as a Mach-Zehnder modulator, this device generates on/off pulses of light using interference. The light beam from a continuous wave (CW) laser is split in two, with each passing through a second length of fibre. An electrical voltage is applied to each fibre, changing its refractive index and thus altering the phase of each light wave in a controlled manner. The two waves are recombined. If they have been put out of phase they subtract, and the light beam is turned 'OFF'. Based on the principle of th Mach-Zehnder interferometer.
