Amplified CWDM system available

Swedish system vendor Transmode Systems AB has developed a new generation of Coarse Wavelength Division Multiplexing systems using Linear Optical Amplifiers.

It claims that the development means that CWDM can address markets traditionally reserved for DWDM (Dense Wavelength Division Multiplexing). Amplified CWDM systems can address long-reach applications very efficiently.

"Linear optical amplifiers have the potential to be as important for the CWDM systems as the Erbium Doped Fibre Amplifiers (EDFA) has been for the long-haul transmission market", says VP R&D Johan Sandell. "This opens up a number of new applications for us where longer transmission reaches are required".

"The introduction of amplified systems will open up new markets for us. We are introducing a cost-effective solution for amplified WDM requirements", says CEO Isaac Olasoko.

Since 2000 Transmode has focused on CWDM technology as a key optical technology to fully exploit the existing networking protocols. The company has been shipping CWDM systems since March 2001 and has customers worldwide.
