Thin film filter technology, which is commonly used in long haul and metro access fiber-optic telecom, can also be utilized to cater to the increasing requirements for datacom optical filtering.
Datacom filter solutions are now available to address these needs:
- Wavelength division multiplexing (WDM) in transceivers separating or combining multiple (typically four) different wavelengths onto a single device
- WDM regions covering include O-band (1260 - 1360nm), C-band (1530 – 1565 nm), and L-band (1565-1625 nm)
- Silicon (Si) Etalons for TLA providing controlled free-spectral range (FSR), finesse, and tunability to enable selection of specific wavelength peaks
Datacom filters often have similar optical functionality and requirements as traditional telecom filters however the optical design, filter size and thickness may be customized to meet the unique requirements of these ultra-compact products.
