Fiber-optic laser
QLM3S910 (isolated) and QLM3S900 (non-isolated) lasers feature thermal-electric coolers that perform at -40 to +85C and -20to +65C, respectively. Optical attenuation in singlemode fiber at 1310 nm is less that 0.5 dB per kilometer. Uses for the laser include antenna remoting/testing, radar communications, delay lines, radio-telescope links and long-distance analog-transmission applications.
