1552.93nm 20mW DFB激光器 熱電制冷 保偏光纖
The CQF975 is a C-band High Power DFB module with Polarization Maintaining (PM) fiber. This module is suitable to use as CW light source for external Mach-Zehnder modulator for use in 2.5Gb/s and 10Gb/s digital optical communication systems or as the laser source for analog externally modulated transmitter. It features 20mW minimum output level, a built-in optical isolator and TEC. It is housed in a 14-pin butterfly package.
For DWDM applications. an integrated wavelength locker stabilizes the laser wavelength. The CQF975 features high side mode suppression ratio, very low PIN nose and narrow laser linewidth and maximum output power of 40mW.
