Omron has added a range of compact and highly reliable bi-directional PLC splitter modules targeted at FTTx Passive Optical Networks, DWDM and CWDM systems, optical cable TV and other outside equipment applications. The introduction of the P1C silica on silica planar waveguide device (PLC) splitters follows the recent acquisition of NHK Spring Optical Communications Components Business. Each device is a packaged optical waveguide chip based on patented plasma chemical vapour deposition (P-CVD) technology. The combination of PLC structure and P-CVD process technology provide exceptional stable optical characteristics and superior reliability compared with fused biconical taper (FBT) technology. In addition, the splitter modules exhibit low insertion loss, low polarisation dependent loss and high port uniformity. The splitters are tested to Telcordia GR1209 and GR1221. Modules available include 1x4, 1x8 and 1x16, 1x32, with a 1x64 planned for mid 2007. Optional custom packaging, metal fittings and connectorised cassette modules also available.
