EXFO FTB-5240S-El Optical Spectrum Analyzer Module

FTB-5240S

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 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 new and unique challenge as the existing OSNR measurement methods yield incorrect results. EXFOﾒs polarization-resolved optical spectrum OSNR (PROS-OSNR) method is the answer to this new challenge, providing reliable in-band OSNR measurement.

SHARP AND ACCURATE OSNR MEASUREMENT
The IEC subsystem test procedure 61280-2-9 defines OSNR measurement as the power ratio between the peak power and the noise at half the distance between the peaks. Using this method, as shown in figure 1, the noise level at the channel (or peak power) wavelength (Ni) is interpolated from the noise level between the channels (N(?i + ??) and N(?i - ??)). Figure 2 shows the OSA trace of a DWDM network where the interpolation method can properly troubleshoot the optical layer. 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. For instance, Figure 3 displays closely spaced 40G signals that require in-band OSNR measurement, since the power level between channels is higher than the actual noise due to channel overlap. The built-in polarization-resolved optical spectrum method of EXFOﾒ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.

CHOICE WITHOUT COMPROMISE
The all-new FTB-5240S and FTB-5240BP Optical Spectrum Analyzer (OSA) series covers your DWDM applications and all channel spacings, from 50 GHz DWDM to CWDM. This is what we call ﾓno-compromise performanceﾔ, whatever your network specificities and testing requirements.

NIMBLE OSA MEETS SUPERTECH PLATFORMS
The FTB-5240S OSA test module, housed in either the FTB-500 Platform or the FTB-200 Compact Platform, is purpose-built for fast and accurate dense wavelength-division multiplexing (DWDM) network commissioning and high-speed networking up to 40 Gbit/s.Housing the FTB-5240S in the FTB-200 platform makes it the smallest, high-performance, portable solution for spectral characterization of next-generation networks on the market. When equipped with in-band OSNR measurement capabilities, this versatile OSA can also be combined with the FTB-8140 Transport Blazer test module to create a unique test solution for commissioning reconfigurable optical add/drop multiplexers (ROADMs), packet optical transport platforms (POT-Ps) and 40 Gbit/s systems.

ADVANCED EDFA ANALYSIS
Since amplifiers are critical elements in all networks, it is crucial to ensure that they are optimized, that the gain is well-distributed and that the output power is flat. Now, you can further optimize EDFAs by measuring key parameters such as gain per channel, noise figure, gain flatness, gain slope, etc. More importantly, you can save and print this precious information.

DRIFT MEASUREMENTS
You can now monitor power, wavelength and OSNR over time. Follow the evolution of these critical parameters, set relative or absolute thresholds and get alarm notifications when they are crossed. You can also view the current and historical status of all channels in a single view called the dashboard and view the WDM trace of any acquisition that displays a change of state (i.e., when a threshold is crossed).

ACCURATE SPECTRAL TRANSMITTANCE
With the advent of larger spectral content through the implementation of 40G and 100G, knowing the bandwidth of any given filter and the residual network bandwidth guarantees proper transmission. The new Spectral Transmittance software feature now compares the filtered wavelength to the nominal one, showing insertion loss, channel isolation and bandwidth at different power levels.

IN-DEPTH DFB LASER ANALYSIS
Make sure your transmitters are within specifications. With the DFB Laser Analysis feature, you can now characterize a DFB laser source for central wavelength, peak power, bandwidth, side-mode suppression ratio (SMSR) and much more.

FASTER IS ALWAYS BETTER
Testing speed is critical, which is why EXFOﾒs FTB-5240S and FTB-5240BP OSAs can complete a scan and display the results in less than one secondﾗthatﾒs fast enough for highly efficient network element adjustments on the go.

HIGH-POWER OPTION
With todayﾒs high-power signals making their way into the DWDM space, it is critical to have an OSA that can measure them accurately without risking damaging your test equipment. The FTB-5240S matches this need, offering a high-power option (FTB-5240S-HPW) allowing up to +23 dBm input power per channel. The option is available with or without the in-band capability.
