OSNR MEASUREMENTS UP TO POL-MUX 40G/100G

OSNR has long been recognized as a key performance indicator in wavelength-division multiplexing (WDM) networks, becauseit provides a multichannel assessment of signal quality in a very short time. In addition, OSNR can predict bit error rate (BER) within just a few minutes, while typical BER tests must run for hours or days.

The IEC 61280-2-9 standard defines OSNR measurement as the power ratio between thesignal 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, because the noise level between the peaks is no longer directly correlated with the noise level at the channel wavelength. EXFO’s in-band OSNR is the answer to this challenge.

For Pol-Mux signals at 40G and 100G, neither the IEC nor the in-band method work. This calls for a new measurement method: Pol-Mux OSNR.

FIRST POL-MUX OSA IN THE MARKET

EXFO’s Pol-Mux OSA is the first third-party instrument for Pol-Mux OSNR measurements that is not limited to any specificsystem vendor. The new commissioning assistant, which is the key feature of the new Pol-Mux OSA, is perfect for Pol-Mux OSNR measurements during turn-up. Based on the channel shutdown method, it provides highly accurate amplified spontaneous emission (ASE) OSNR measurements.

The commissioning assistant can be utilized after the user has first taken a measurement at the receiver with all of the channels turned on, and then acquired a series of traces, each taken with one channel turned off. The Pol-Mux OSA then performs the Pol-Mux OSNR calculations via a user-friendly wizard.

The commissioning assistant therefore greatly accelerates OSNR measurements based on the channel shutdown method, and drastically reduces potential human errors. In addition, two standards-compliant calculation approaches are available in the commissioning assistant: one compliant with the IEC-61282-12 standard (under revision), and the other compliant with the China Communications Standards Association (CCSA) method YD/T 2147-2010.

WDM-AWARE TECHNOLOGY

  • Intelligent setup and analysis on a per-channel basis based on the bit rate, modulation scheme, as well as the network configuration experienced by the wavelength (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

ANALYZE ANY WDM NETWORK

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.

Join us as we explore the real-life case study of a 17 Channel High Speed DWDM system exhibiting correctable FEC errors. As this network was carrying extremely high traffic, identifying the issue on this live, in service link without compromising the network was a challenge. The customer needed the right tools along with the right troubleshooting approach to pinpoint the problem and solve it quickly. The webinar will benefit anyone who is charged with maintaining, or upgrading a DWDM, high speed network.
