Frequently Asked Questions (FAQ)
Q
What standard do the center wavelength (λc) specifications of these 2.5G GPON filters comply with?
The center wavelength (λc) specifications fully comply with the standards established by the International Telecommunication Union (ITU).
Q
What is the operating temperature range and thermal drift for these filters?
These filters are designed to operate reliably within a temperature range of -40℃ to +85℃, featuring a low thermal drift (△λ/△T) of less than 2 pm/°C.
Q
What are the physical dimensions of the standard 2.5G GPON filter?
The standard dimensions for these GPON filters are 1.1(±0.05) * 1.1(±0.05) * 0.2(±0.05) mm.
Q
What are the incident angles available for these GPON filters?
We offer variants designed for different incident angles, including 0° (with a passband of 1480-1503 nm) and 45° (with a passband of 1260-1360 nm).
Q
What is the performance of the Backside AR Coating on these filters?
The Backside AR Coating is optimized to minimize signal loss, achieving a reflectivity performance of 0.2%.
Q
Can I request custom specifications if my required configuration is not listed?
Yes. If you cannot find the specific configurations you require in our current stock list, please contact us directly to discuss custom manufacturing options.
