Filter-Based Wavelength Division Multiplexer
Filter-based Wavelength Division Multiplexer (Filter WDM, or FWDM) is based on the mature membrane filter technology, with a wide channel bandwidth, low insertion loss, high channel isolation degrees and high environmental stability and reliability. It is widely used in single-mode fiber optic communication systems and DFA. FTTX Filter WDM module is based on Thin Film Filter (TFF) technology.
The Filter-Based WDM is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. The FWDM series is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range.
They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. In Sopto, Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier and EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm (for high performance DWDM optical amplifier and EDFA) and 1310/1490/1550nm (for PON, FTTX and test instrument). 1310/1490/1550 FTTX FWDM is based on filter based platform for optical device.
This multiplexer is ultra-low loss, high isolation, and high reliability. Sopto 1490nm/1310nm/1550nm FTTH FWDM can realize the multiplexing and de-multiplexing of two communication signal 1490nm/1310nm and 1550nm. It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
As you might know, GEPON system itself works on 1310nm/1490nm, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get’s “mixed”.
