Tunable Laser Source

Brand:EXFOModel:FLS-2600B

The FLS-2600B Tunable Laser Source is ideal for testing dense WDM components in the C- and L-band ranges. With a 1 pm resolution and an impressive signal-to-spontaneous-emission ratio (SSER) of 75 dB, this source is optimized for passive component testing. The FLS-2600B’s clean signal provides a superior dynamic range, allowing you to measure isolation greater than 65 dB.

Key Features
Also available as a platform-based module (IQS-2600B), the FLS-2600B is ideal for completely characterizing (IL, ORL and PDL) DWDM passive components. Its naturally low spontaneous emission enables a > 75 dB dynamic range. Thanks to its tuning range of > 100 nm, it covers both the C and L bands (wavelength tuning from 1510 nm to 1612 nm) with an output power of 0 dBm over the 1515 nm to 1610 nm range.

Designed Around Your Testing Needs
The tunable laser source integrates both a monitor output port and a main output port. The monitor port, which is essentially a 5 % tap from the laser cavity, is useful for real-time wavelength monitoring in tests where optimum wavelength accuracy plays a major role. In addition, the main output is regulated in output power and can be attenuated over a 10 dB range. The triggering capability simplifies external synchronization with other instruments such as optical spectrum analyzers, power meters or simple oscilloscopes.

Low Spontaneous Noise Emission
Over the 1515 nm to 1610 nm range, the IQS-2600B and FLS-2600B provide more than 75 dB local noise suppression and more than 45 dB in signal-to-total-noise ratio, making them ideal for testing both stopband (notch) and passband filters. When combined with the source’s coherence properties, they are the best tunable lasers on the market for characterizing passive DWDM components.

Fast GPIB and Wavelength Tuning
Maximize your efficiency by taking advantage of both fast tuning and effective remote control with the FLS-2600B stand-alone configuration. Use the GPIB access to complete a 50 pm step setup, including laser position confirmation, in about 60 ms, and benefit from more time for measurements, while reducing time spent on wavelength tuning.

Step-by-Step or Continuous Sweep
Both FLS-2600B configurations support programmable sweep functions. Choose between continuous and step-by-step approaches, depending upon your specific application.

To obtain a loss profile, use continuous tuning at up to 50 nm/s in real time to perform optical alignments or maximize transmission during device processing. When coupled with one of EXFO’s fast power meters, the result is an efficient and compact alignment station.

Optimum wavelength accuracy takes precedence over test time or the number of acquisition points in some situations. For example, testing WDM components for PDL at ITU grid wavelengths typically requires a stop and measure approach in step-by- step mode. Whichever sweep mode is used, the laser is mode-hop free over the entire tuning range.

Input and output triggering for synchronization is available. This function eases integration of the tunable laser source with external measuring devices, including oscilloscopes, voltmeters, optical spectrum analyzers or power meters.
