Bandwidth9 plans to introduce a line of tunable optical transmission modules enabling Wavelength-on-Demand systems for remotely provisioning bandwidth through Metro WDM infrastructures.
The flexible modules also provide a solution for ‘Hot Standby’ spares for Metro fibre-optic equipment. The modules allow for new designs of optical cross connects, metro transport systems, and optical access systems. In addition, these tunable modules enable spares replacement designs that replace as many as 60 fixed wavelength laser sources in metro systems. The tunable modules will be capable of covering either the C band (1530-1564nm) or the L band (1580-1620nm) and will be available for select customers by year-end.
The initial product is a completely integrated evaluation card that consists of a broadly tunable, directly modulated, semiconductor laser source, an erbium-doped fiber amplifier (EDFA) and the hardware, firmware and programmable logic that provides repeatable, tunable wavelength and power control, all provisioned remotely via a graphical user interface (GUI). The laser source is directly modulated at speeds up to SONET OC-48 or SDH STM-16 data rates.
‘Both equipment manufacturers and carriers have already indicated their needs for these modules as a simple and effective sparing solution as well as for dynamic Wavelength-on-Demand system architectures,’ said Hatch Graham, chairman and chief executive officer of Bandwidth9.
Tim Richardson, executive vice president of business development added, ‘Our transmission modules provide a cost-effective solution by being broadly tunable across both the L and C bands, directly modulated, and in a package with a very small footprint.’
Bandwidth9’s tunable fiber-optic components and modules for telecommunications are based upon the vertical cavity surface emitting laser (VCSEL) and optical micro-electro-mechanical structure (MEMS) technologies.
