USource passive WM1 module multiplexes and demultiplexes up to 4 TWDM PON wavelengths for downstream and upstream connectivity between Optical Line Terminal (OLT) transceivers and Optical Network Units (ONUs) in an NG-PON2 system. All ports provide bi-directional connectivity for upstream and downstream wavelengths over a single fiber.

Channel 1 Central wavelength 1532.68 and 1596.34 nm
Channel 2 Central wavelength 1533.47 and 1597.18 nm
Channel 3 Central wavelength 1534.25 and 1598.04 nm
Channel 4 Central wavelength 1535.04 and 1598.89 nm
