Triplex Filter (Triple-Play Filter) is an Optical Communication Filter specially designed by MULTI IR for the "voice, data, video" triple-play scenario. Its core function is to separate the wavelength signals corresponding to three different services in a single optical fiber, realizing "one line for multiple uses". The product integrates the dual advantages of Dichroic Mirror and High Transmittance Filter, with a reflectivity of ≥ 98% for voice signal wavelength (such as 1310nm), a transmittance of ≥ 95% for data signal wavelength (such as 1490nm), and a transmittance of ≥ 95% for video signal wavelength (such as 1550nm). The crosstalk between the three types of signals is ≤ -38dB, and the insertion loss is ≤ 0.4dB, which can completely avoid inter-service interference. This product is compatible with the triple-play module of FTTH Optical Network Unit (ONU), and the packaging size is compatible with 2.5×2.5mm, meeting the miniaturization needs of home user end equipment; at the same time, it has high reliability, and the performance does not attenuate after 1000 plug-in tests and 10000-hour operation tests; combined with MULTI IR's mass production capacity, the cost is controllable, and it is a core component of FTTH construction under the "triple-play" policy.
