1541.35nm 20mW DFB激光器 热电制冷 保偏光纤
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 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 a built-in optical isolator and TEC. It is housed in a 14-pin butterfly package.
