Our Single-mode Planar Lightwave Circuit Splitter (PLCS) are developed based on unique silica glass waveguide process with reliable precision aligned fiber pigtail in a minia-ture 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 wave-length range from 1260nm to 1620nm and working in temperature from -40 to +85. The PLCS devices have standard configurations of 1*4, 1*8, 1*16, 1*32, 1*64, 2*2, 2*4, 2*8, 2*16 and 2*32.
