Proposing integrated design and development for everything from custom fibers to optical devices

Optical fiber and related productsWe can develop proposals for the development and

manufacturing of custom fibers, including single-mode

fibers and multi-mode fibers from Photonic Science

Technology. In addition to optical fiber development and

manufacturing, we also offer assembly services including

fiber termination, arraying, bundling and high-powered

connectors.

Helping local governments distribute disaster prevention information

Disaster Prevention Information Distribution SystemsWe have participated in the J-alert（nationwide simultaneous warning system） project

from its design and field demonstration test phases and are currently carrying out

development, manufacturing, sales, and maintenance of J-Alert receivers.

We also offer a comprehensive disaster prevention information distribution system for

local governments, which realizes diversification of transmission methods to citizens by

combining the wireless communications with software development.

This system removes the burden of parallel operations of multiple systems and allows

quick delivery of the alerts distributed via J-Alert to various transmission methods such

as SNS linkage and CMS (WEB) linkage.

The system was employed for “Field demonstration tests on multi-transmission

methods for disaster prevention information (in Koto Ward),” which was conducted

through cooperation with the Fire and Disaster Management Agency (FDMA) of the

Ministry of Internal Affairs and Communications, and by Tomigusuku City, Okinawa, etc.

In addition to J-Alert distribution, it is providing evacuation guidance and voice

transmission to evacuees by establishing wireless connections among outdoor

speakers, and digital signages and Wi-Fi spot services by extending wireless networks

to elementary schools, which will act as evacuation centers, and evacuation routes.

Teltonika Networks' IoT Router for Industrial IoT/M2M

This IoT router is equipped with Wi-Fi communication for LAN and the 4G/LTE

communication for WAN. It has a fail-over function for WAN. Therefore, when a

wired LAN is down in WAN, it switches the communication link to 4G/LTE to

enable continuous use of the network.

In addition, the router has firewall and

other security features for industrial

applications and also provides remote

management system (RMS) of devices.
