A US based start-up is working on technology to make a beam of light travel further over telecoms based fibre optic networks without any quality degradation.
Lasercomm has developed a so-called Dispersion Management Device (DMD), which connects to a fibre optic network and is based on the company's spatial mode transformation (SMT) technology. SMT enables fibre optic systems to be put into the network without requiring as many regenerators as is currently the case.
Mark Barratt, Lasercomm's vice president of business development, said: "This single fibre is capable of transmitting billions of bits per second without much quality loss, unlike traditional copper line based networks, which have limited capacity and experience quality drops."
He explained that, in long distance networks, light goes through a fibre and travels at different speeds rather than a constant one. "Our device at Lasercomm allows us to reverse the affect of the dispersion in the fibre and we control the speed of the light. No one has ever been able to do this before," he claimed.
He added that the large scale telecoms carriers and long distance suppliers were interested in the technology because it enabled voice data to travel over longer distances without the need for them to change their existing equipment.
It also enabled them to add more capacity to the fibres they were already using and to manage chromatic dispersion. This is the tendency of light pulses to spread out as they travel through a given medium.
Lasercomm's first DMD product, Himode, is currently in beta, and corrects dispersion and dispersion slope, which enables carriers to add more channels and offer faster bit rates, while reducing network operating costs.
The offering will initially be sold in the US, but the company is also in talks with some European companies.
Lasercomm is a privately held company based in Richardson, Texas' famous "Telecom Corridor," and has 52 employees. It also has a research and development subsidiary in Tel Aviv, Israel and has just closed a $14 million round of financing.
