SOLUTION FOR NEXT-GENERATION NETWORKS
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 an accurate measurement of optical signal-to-noise ratio (OSNR), but ROADM and 40 Gbits/s networks present a unique challenge as the existing OSNR measurement methods yield incorrect results. EXFO’s 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. Using this method 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 EXFO’s 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.
- Intelligent setup and analysis on a per-channel basis based on the bit rate, modulation scheme, as well as the network configuration experience by the wavelenght (ROADM, filters, etc.)
- First time right: no guesswork, which eliminates truck rolls
- Training time is significantly reduced as this ready-to-go unit can be taken directly into the field for the live EXFO DWDM experience
- Most accurate and adaptive in-band method on the market
CHOISE WITHOUT COMPROMISE
The FTB-5240S and FTB-5240BP Optical Spectrum Analyzer (OSA) series covers your DWDM applications and all channel spacings, from 25 GHz DWDM to CWDM. This is what we call "no-compromise performance", whatever your network specificities and testing requirements.
