Optone’s single-mode Planar Lightwave CircuitSplitter(PLCS) are developed based on unique silica glass waveguide processwith reliable precision aligned fiber pigtail in a miniature package, itprovides a low cost light distribution solution with small form factor and highreliability. The PLCS devices have high performance in terms of low insertionloss, low PDL,high return loss and excellent uniformity over a wide wavelengthrange from 1260nm to 1620nm and working in temperature from -40ºC to +85ºC. ThePLCS devices have standard configurations of 1x4, 1x8, 1x16 and 1x32configurations, as well as customized structures of 2X8, 2x16, 2x32 and 2x64.
