With fast tuning speed, low insertion loss, these tunable filters raise the bar of filter performance. The Optannel tunable filters are small enough to be seamlessly to be integrated within today’s electronic systems. Based on optannel’s all fiber-based tunable filter technologies and by employing a specified collimating lens as small as the optical fiber. The Optannel optical tunable filter achieves high finesse and maintains low loss across a wide range of frequencies. The side modes are suppressed within the working range.
