1558.58nm 40mW DFB激光器 1MHz線寬 保偏光纖
The CQF935 is a C-band High Power DFB module with Polarization Maintaining (PM) fiber. This module is suitable to a CW light source for external modulator integration in 10Gb/s and 40Gb/s digital optical communication systems or as the laser source for analog externally modulated transmitter. It features a built-in optical isolator and TEC. It is housed in a 14-pin butterfly package. Features: 40 mW output at 250 mA; Narrow line width <1 MHz; Fully tested to 45 mW.
