The single-mode Planar Lightwave Circuit Splitter (PLCS) are developed based on unique silica glass waveguide process with reliable precision aligned fiber pigtail in a miniature package, it provides a low cost light distribution solution with small form factor and high reliability. The PLCS devices have high performance in terms of low insertion loss, low PDL, high return loss and excellent uniformity over a wide wavelength range from 1260nm to 1620nm and working in temperature from -40ºC to +85ºC. The PLCS devices have standard configurations of 1x4, 1x8, 1x16 and 1x32 con- figurations, as well as customized structures of 2x16, 2x32 and 2x64.
