C波段可調諧激光器 帶波長掃描


The Optilab TLS-C-B is a high spectral purity and stable tunable wavelength laser source capable of sweeping the extended C-band in 100 ms.

Product Overview

The Optilab TLS-C-B is a high spectral purity and stable tunable wavelength laser source capable of sweeping the extended C-band in 100 ms. The TLS-C-B features a unique ability to either set the wavelength or sweep the entire C-band or a select section, and features wide wavelength tuning range, narrow laser linewidth, high Side Mode Suppression Ratio (SMSR), excellent wavelength stability, and optical output level up to 30 mW. With the standard Polarization Maintaining (PM) fiber output, TLS-C-B offers a linearly polarized output. These features makes TLS-C-B well suited for many different applications, including DWDM device testing, optical sensing and laboratory measurement applications. It includes an RS-232 Interface for remote operation in laboratory environments. Contact Optilab for more information.
