Introduction Optical transmission uses pulses of light to transmit information from one place to another through an optical fiber. The light is converted to electromagnetic carrier wave, which is modulated to carry information as the light propagates from one end to another. The development of optical fiber has revolutionized the telecommunications industry. Optical fiber has […]
WDM Filter
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 […]
