Responding to the global spread of FTTH (Fiber-To-The-Home), we are developing a range of optical cables that connect each home to the telephone exchange. To allow the economical construction of FTTH broadband networks, in recent years we have been working on the development of innovative optical cables such as thin light cables and low-friction cables that can make effective use of existing conduits and aerial cable facilities, cables featuring easy installation and connection and high bending resistance, and ultra-thin cables that can be run through the crack under a door or the gap between a sash and the frame.

In addition to optical fiber cables, we develop optical fiber cable joint products those support infrastructure of optical cable networks such as FTTH. There are optical cable joint products such as optical termination racks that contain a large number of optical fiber cables drawn into network center, closures for jointing optical fiber cables running outdoors, and optical termination boxes installed at subscribers' premises. We develop them to pursue functionality and workability to meet the requests of customers.

As we move towards a ubiquitous network society, applications such as image distribution and cloud services are evolving day by day. We are working on the development of mechanical splicers and field-assembly optical connectors that provide technology for constructing economical optical access networks to serve as the foundation of information technology. Applying the technology accumulated through the development of various optical connectors, we are also committed to research and development on connectors for optical interconnections in high-end telecommunications equipment and supercomputers.

With the widespread use of communication and broadcasting through optical networks, the maintenance and management technology for supporting their operation has been growing importance. We are developing optical fiber monitoring system for identifying failure location in optical fiber network, optical switch for selecting monitored optical fiber and optical fiber management system for designing/maintaining complicated optical fiber network on GIS.

Dense Wavelength Division Multiplexing (DWDM) networks are widely deployed in metro networks and Reconfigurable Optical Add Drop Multiplexwer (ROADM) is becoming important network application which allows flexible network operation by switching of wavelengths channel within, into and out of a fiber in the network. WSS is the indespensable component in the ROADM system and contributes to the achievement of functonality requirements for the next generation ROADM network. Highly functional and reliable WSS products have been developed based on advanced free-space optics and functional design technologies and launched on the market in partnership with Nistica (U.S.).
