1550nm Butterfly DFB laser diode DFB butterfly laser diode module is equipped with MQW-DFB laser diode chip. By using DFB grating to produce and control laser. The laser diodes from Vfibre features high linearity and high power, 14 pin butterfly cooled package, long center wavelength reach from 1540nm to 1560nm, spectral width from 0.1nm to 1nm, output power from 2mW to 12mW, low threshold current and operating voltage. Because of low loss in high speed and long distance transmission, it can be used as a light source in CATV forward path 1310nm, 1550nm broadcast and point to point application. Feature High linearity high power MQW DFB LD chip Built-in isolator 14-pin butterfly cooled package Output power 2~24mW Application 2.5 Gb/s long haul DWDM Transmission CATV forward-path
