Internet plays an important role today. Nearly, all of us seem to live and work with it every day. As life revolves around it, the internet has been improving leaps and bounds, and its technology keeps advancing. Every household has a connection and can experience plenty of benefits. FTTH(fiber to the home) is one of the latest broadband network architectures, and this method for home use uses fiber optics that can transfer large data effectively. To install and maintain the network, it needs lots of FTTH components that must work seamlessly around the clock. And Korea’s PPI (Photonics Planar Integration) has been contributing to the development of high speed internet.

Started in 1999, PPI as a venture business began producing its flagship item, optical power splitters. Based on PLC(Planar Lightwave Circuits)’s fundamental technology, PPI offers core parts for several network architectures. Two major items such as optical power splitters and AWG(Arrayed Waveguide Grating) are reaching globally, and also Korea’s giant communication carriers KT and SK Telecom are among its main clients.

Optical Power Splitter

PPI’s optical power splitters are one of the main components used in building FTTH. The item can separate an electric signal sent from the main telephone or internet cable station, and then transmit it to multiple destinations such as houses and apartments. Its main features include compact size, low insertion loss, and stability. The Arrayed Waveguide Grating (AWG) is one-to-one method for manual optical transmission product, and it can transmit mass storage signal of image, telephone, and data by using only one optical line. There are Athemal and Thermal type.

 Besides FTTH, applications are CATV, LAN, WAN system, and network monitoring systems. PPI also offers the other component items like fiber distribution frames, high power splitter modules, couplers, easy-to-use optical mode conversion adapters with double mode (Multi and Single).

PPI has been selected as the KOTRA Seal of Excellence since 2010
