Description

C-band tunable SLED Light Source DFB laser DFB-C-WT type

The DFB-C-WTx tunable laser is a continuous light (CW) output designed for DWDM dense wavelength division multiplexing systems, and the wavelength tuning range covers the fixed wavelength interval of the C Band (ITU-T standard wavelength standard) (channel spacing 50 GHz) A benchtop tunable laser source. The built-in laser component integrates a dual FP cavity temperature tuning etalon with high output optical power (20mW), narrow linewidth, and high wavelength accuracy. Embedded DSP processor and wavelength locking unit, optimized frequency stabilization mechanism makes the wavelength frequency error less than 1.5GHz, power stability less than 0.3dB, power difference less than 0.5dB in the full wavelength range.

Application:

Optical fiber sensing system
Biomedical imaging
Fiber optic passive device measurement
Wavelength division multiplexing device test
