filter ripple specified in nm, not dB?
I'm looking for some ITU G694.2 filters to use in an upcoming project, and found an inexpensive one: {12}72{9}22{6}56The ripple is listed in nm, rather than in dB over the pass band. I'm not sure what...
 
TOSA mounting.
I have a project that will be transmitting 10,000 analog signals of bandwidth 1.5 GHz a distance of 3 km. I had thought about using individual laser diodes in TOSA packages to do this. I have never...
