Optical Filter
Santec‘s optical filters include the MTF series is a noise reduction filter for optical communications developed using electrostatic MEMS (Micro Electro Mechanical System) technology. It is mainly incorporated into optical transceivers for data communications and supports next-generational small transceiver standards such as SFP (Small Form-factor Pluggable) and CFP2 (C Form-factor Pluggable 2). This filter effectively removes noise generated during optical signal transmission within the fiber, reducing unnecessary noise light remaining after amplifying the optical power. As a result, the signal quality is improved and helps stable operation of optical communications. It is particularly effective in long-distance transmissions using EDFA (Erbium-Doped Fiber Amplifier) and high-density networks such as WDM. The MTF series is also expected to be applied not only in telecommunications but also in cutting-edge fields such as space communications, laser spectroscopy, quantum optics, and precision sensing.
In addition, the WSS-2000 is an LCOS-based programmable optical filter that supports bandwidth tuning, attenuation, switching, and phase control, making it ideal for evaluating next-generational optical networks.
