Butterfly Fiber Coupled Laser Diodes
The butterfly fiber coupled laser diodes adopt the high-quality MQW-DFB chip in order to meet the requirement of a high-speed, specific-wavelength light transmission system. The built-in thermo-electric cooler enables the laser device to run stably under various environmental conditions. This series of product has found wide applications in the LAN, WAN, MAN, CATV transmission system, and long distance DMDW transmission system. It also can be used in the stabilized light source, modulated light source, or other communication equipment such as the CATV transmitter.
