Description
Customized Filter WDM, FWDM Band Splitter
Arkoptics provides FWDM device(filter-based wavelength division multiplexing filter device) that is customized for specific wavelength bands for your special applications. The FWDM combines filters with multi-channel multiplexers, enabling it to reflect, transmit and manipulate signals of different wavelengths. Due to its low insertion loss, low polarization dependence and high isolation, the FWDM filter is widely used in CATV system, FTTx, PON systems, Fiber Communication, Raman Amplifiers, EDFA, Test Instrument and etc.
Typically, GEPON systems operate on 1310/1490nm, so the CATV signals here are transmitted over the same fiber using 1550nm, and FWDM is the component that “mixes” all these signals. Also, the Filter WDM system uses Multiplexers at the transmitter to combine several wavelengths together, each carrying a different signal with a bite-rate up to 10G, and use demultiplexers at the receiver to split them apart. FWDM can expand the capacity of a single fiber to achieve bidirectional communication, so it is widely used in optical network upgrades and expansion, or introduce new comprehensive business, etc.
