1490nm Optical Fiber Filter High Transmission Rate Fiber Filter

This is 1490nm (1480nm) wavelength fiber filter device. Thanks to the special filter elements and unique production process, HTF1490T has the function of efficiently passing light at 1490nm (1480nm) wavelength and deep-cutting at 1310nm (1300nm), 1550nm, 1625nm and 1650nm wavelengths.

1. High transmission rate
2. Deep cutoff
3. More cut-off wavelength
4. Low polarization dependent loss
5. Small size
6. High stability

1. WDM channel
2. Optical instrumentation
3. FTTX optical path
4. Research and production of optical devices and optical machines
