High-Performance Tunable Laser Source

Also available as a platform-based module (IQS-2600B), the FLS-2600B is ideal for complete characterization of fiber-optic filters, 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.


Second Generation Specifications and Design

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.

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.
