10MW 1310nm DFB butterfly laser module

DFB butterfly laser module is specialized for adopting the high-quality MQW-DFB chip to meet the requirement of a high-speed, specific-wavelength light transmission system. It can be used for continuous-wave and pulsed applications such as sensing, frequency doubling, light detection and ranging, and injection seeding for fiber amplifiers or lasers.

Fiber-Mart 10MW 1310nm DFB butterfly laser module produces laser beams with a particular wavelength. It is able to deliver output power of 10MW. The 14-pin butterfly laser module will be supplied with a built-in optical isolator, a monitor photodiode, a thermoelectric cooler, and FC/APC connector and is pigtailed with a polarization-maintaining fiber. The built-in thermoelectric 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.
