FWDM

HJY provides filter-based wavelength division multiplexing (WDM) filter devices that are customized to the particular wavelength bands for your special applications. As you might know, the GEPON system itself works on 1310/1490, so the CATV signal here is delivered over the same fiber using 1550nm, and FWDM is a place where all this get's "mixed FTTX Filter WDM module extensively used in EDFA, Raman amplifiers, WDM networks, and fiber optics instrumentation is based on Thin Film Filter (TFF) technology. The device combines or separates light at different wavelengths in a wide wavelength range. It can expand the capacity of a single fiber to achieve bi-directional communication so that widely used in optical network upgrades and expansion, or introduce new comprehensive business, etc FWDM covers the following wavelength windows commonly used in optical fiber systems: 850/1310nm FWDM - for multi-mode fiber communication, CATV and testing instrumentation. 1310/1550nm FWDM - for WDM or DWDM optical communications. 1480/1550nm FWDM - for high-power DWDM optical amplifier and EDFA. 1510/1550nm FWDM - for DWDM multi-channel optical networks. 980/1550nm FWDM - for high performance DWDM optical amplifier and EDFA amplifier. 1310/1490/1550nm FWDM - for PON, FTTX and test instrument. 1310/1550/1625nm FWDM - for testing active fibers in service. 1310/1490/1550/1625nm FWDM - for combining or separating 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm so that 1625nm channel can be added into the existing triplex FTTH system.
