Frequently Asked Questions (FAQ)
What is the operating wavelength range of the LWDM filter?
The operating wavelength range for this LWDM (LAN-WDM) filter is 1260.0 nm to 1330 nm, complying with the standards of the International Telecommunication Union (ITU).
What are the dimensions and tolerance specifications of the filter?
The standard dimensions are 0.757 (±0.03) mm × 0.757 (±0.03) mm with a thickness of 0.6 (±0.025) mm.
How stable is the filter under temperature fluctuations?
The filter features excellent thermal stability with a thermal wavelength drift (△λ/△T) of less than 2 pm/°C across an operating temperature range of -40°C to +85°C.
What is the polarization dependent loss (PDL) and insertion loss (IL)?
The filter has a maximum passband PDL of less than 0.1 dB and a peak insertion loss (IL) of ≤0.33 dB, ensuring minimal signal attenuation and high-quality optical performance.
Does the LWDM filter have anti-reflection coating?
Yes, it is designed with a backside AR (Anti-Reflection) coating featuring a reflectivity of 0.2% to optimize transmission efficiency and minimize back-reflection.
