Fiber Bragg Grating Tunable laser module
Describe:
Tum-L4900-A’s tunable laser module has the characteristics of accurate wavelength, stable power and fast scanning speed, and is widely used in fiber grating demodulation systems and optical passive device testing systems. Under the 1GHz scanning step, the scanning speed of 2kHz in the 40nm range can be achieved; meanwhile, the scanning speed can be improved by adjusting the scanning step and changing the scanning range.
Features:
● Tunable wavelength range: 40nm
● Scan rate up to 2kHz
● High output power (20mW)
● Good wavelength stability
