Frequently Asked Questions (FAQ)
Do these COMOB filters comply with industry telecommunication standards?
Yes, all of our COMOB filters fully comply with the standards of the International Telecommunication Union (ITU), ensuring high compatibility and performance in telecom network applications.
What is the operating temperature range and thermal stability?
These filters are designed to operate in harsh environments ranging from -40°C to +85°C. They feature an exceptionally low thermal wavelength drift (Δλ/ΔT) of less than 2 pm/°C.
What kind of optical coatings are applied to these filters?
The filters are equipped with a high-performance Backside Anti-Reflection (AR) Coating, achieving a reflectivity of 0.2% to optimize transmission and minimize return loss.
Are custom dimensions or custom optical specifications available?
While our standard stock size is 1.4(±0.05) × 1.4(±0.05) × 0.3(±0.05) mm, we can accommodate custom dimensions, passbands, and incident angles. Please contact us to discuss your specific requirements.
What is the typical insertion loss (IL) and polarization dependent loss (PDL) for these filters?
The COMOB filters exhibit highly efficient optical performance with a Peak Insertion Loss (IL) of less than 0.3 dB and a Passband Polarization Dependent Loss (PDL) of less than 0.1 dB.
