The TFF 1310-1490-1550-1625nm FWDM (Filter Wavelength Division Multiplexer) is a versatile optical device designed to combine or separate multiple wavelengths in a single fiber. This FWDM supports the 1310nm, 1490nm, 1550nm, and 1625nm wavelengths, making it ideal for applications in FTTH (Fiber to the Home), CATV, and broadband networks. It offers excellent isolation, low insertion loss, and high stability, ensuring reliable and efficient transmission of optical signals across various network configurations. The TFF FWDM's robust performance and broad wavelength range make it a crucial component for advanced fiber-optic communication systems.
