Product Specifications
Product Description
The TSL-220 is a high specification tunable laser developed specifically for today's DWDM market. It incorporates an internal wavelength monitor which ensures a wavelength setting accuracy of +/-5pm. A tunable filter is built-in to the unit to remove ASE noise and increase the signal to noise ratio to ten times that of conventional tunable laser designs. This feature, in particular, makes the laser particularly suitable for characterization of fibre Bragg grating and similar DWDM devices. The TSL-220 boasts a full range of other features including an 80nm tuning range covering both C or L band wavelengths; a built-in attenuator enabling power to be controlled independent of laser diode injection current, high stability, GPIB and RS-232 interfaces with LabView drivers; and a useful fully programmable handheld control pad.
The TSL-220 fits into Group's range of tunable lasers alongside the established TSL-210 model, and will find application in both research laboratories and production environments where high specifications and high performance are of particular importance.
