Highly accurate, easy-to-use intelligent optical spectrum analyzers (OSAs) for current and next-generation networks. Optical Spectrum Analyzers for Next-Gen NetworksUp to 100G. Consumers and companies around the world require more bandwidth than ever before for data-hungry applications such as video-on-demand, voice-over-IP (VoIP), videoconferencing, etc. Accordingly, service providers need to deploy faster and more reliable networks, using novel technologies such as reconfigurable optical add-drop multiplexers (ROADM) or 40G/100G networks. Reducing downtime in any type of network calls for accurate measurement of optical signal-to-noise ratio (OSNR), but ROADM and 40 Gbit/s networks present a unique challenge, as the existing OSNR measurement methods yield incorrect results. EXFOs WDM-Aware technology is the answer to this challenge, providing reliable in-band OSNR measurement. The IEC subsystem test procedure 61280-2-9 defines the OSNR measurement as the power ratio between the peak power and the noise at half the distance between the peaks. However, in ROADM or 40 Gbit/s systems, this method may lead to incorrect results since the noise level between the peaks is no longer directly correlated with the noise level at the channel wavelength. However, the built-in WDM-Aware technology of EXFOs FTB-5240S-P and FTB-5240BP OSAs enables you to achieve accurate in-band OSNR measurements of a ROADM or 40 Gbit/s system directly and automatically.
