IQS/FLS-2600B


IQS/FLS-2600B

High-Performance Tunable Laser Source

On the production fl oor, time is money. You need fast, cost-effective test instruments that maximize your production throughput. The IQS-2600B and FLS 2600B Tunable Laser Sources are ideal for complete characterization of fi ber-optic fi lters, multiplexers and other dense WDM components. They are the logical choice for instrumentation calibration and for measuring wavelength-dependent gain, noise contribution and the saturation properties of EDFAs.

Greater Than 100 nm Tuning Range

This second-generation tunable erbium-doped fiber laser delivers exacting wavelength accuracy for long periods of use. Wavelength can now be tuned over a wide range—1510 nm to 1612 nm. Output power is greater than 0 dBm over the critical 1515 nm to 1610 nm range as shown on the right.

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. All this in a two-slot plug-in module. The modular IQS-2600B configuration operates within the IQS test platform.

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! You will have more time for measurements, while reducing time spent on wavelength tuning.

Step-by-Step or Continuous Sweep

Both IQS-2600B and 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 on both IQS and FLS units. This function eases integration of the tunable laser source with external measuring devices, including oscilloscopes, voltmeters, optical spectrum analyzers or power meters.
