Frequently Asked Questions
What standards do these BI-DI filters comply with?
Our BI-DI filters comply with the standards set by the International Telecommunication Union (ITU), ensuring high performance and compatibility in global telecommunication networks.
What is the typical operating temperature range for these filters?
These filters feature an industrial-grade operating temperature range of -40℃ to +85℃, allowing them to perform reliably under extreme environmental conditions.
What are the standard dimensions of the BI-DI filters?
The standard physical dimensions for the stock items are 1.75(±0.05) × 1.5(±0.05) × 0.2(±0.05) mm, featuring a backside AR coating with reflectivity of 0.2%.
What is the thermal drift performance of these filters?
The wavelength thermal drift (△λ/△T) is extremely low, measured at less than 2 pm/°C, ensuring high stability across varying temperatures.
Can I request custom specifications if they are not listed in the stock table?
Yes. The table shows our current stock items. If you require custom wavelengths, different incident angles, or specific packaging dimensions, please contact us directly.
