850nm Super luminescent Diode fiber coupled Output power 5mW
FOG-SLD-850-14BF Superluminescent Diode is a light source
for fiber transmission systems, fiber optic gyros, fiber optic sensors,optical
coherence tomography, optical measurements. The diode is packaged in 14-pin
standard butterfly package with monitor photodiode and thermo-electric cooler
(TEC). Module is pigtailed with 0,7-1,0 m of single mode polarization
maintaining fiber and connectorized by FC/APC connector.
