Yokogawa releases optical spectrum analyser

Yokogawa has launched a new optical spectrum analyser (OSA) designed to offer the extreme high precision demanded by researchers developing the next generation of optical communication components.

With the exponential growth in the Internet of Things, as well as cloud computing services, video broadcasting and conferencing, and the rise in access to mobile broadband, demand for data capacity will expand hugely over the next few years. High capacity optical backhaul networks will be needed to serve this growing traffic density.  Dense wavelength division multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over the existing fiber network.

As data hungry applications push the performance requirements of DWDM systems, telecommunication channels become ever more closely spaced, making it more difficult to separate the individual channels in the wavelength division multiplexing (WDM) analysis on an OSA.

The Yokogawa AQ6380 OSA offers high optical performance to allow engineers and scientists to develop and improve the speed, bandwidth and quality of the next generation of communication networks, while its ease of use ensures it can be operated quickly and efficiently. 

The AQ6380 has excellent optical wavelength resolution down to 5 picometres (pm), allowing optical signals in close proximity to be clearly separated and accurately measured. With the AQ6380, waveforms that were previously not even visible in a typical OSA, such as modulation side peaks in the laser spectrum, can now be accurately visualised.
