kohoku Kogyo: High-performance optical components for submarine cables: World’s top share
-Shiga’s strong companies have no hesitation in strategy-
Next-generation communication network:
The continent of Africa and Europe are seamlessly connected.
The world’s largest submarine cable laying project.
The next-generation communication network is expected to start operation in 2023.
kohoku Kogyo: (Shiga Prefecture)
kohoku Kogyo’s optical devices will also be supplied
High performance and reliability:
Submarine cables are laid in the deep sea as deep as 6000 meters.
In addition, the operation period extends to a quarter century.
Not to mention the cable
For the devices that make up the system
High performance and reliability are required.
Most of the world share:
The company manufactures and sells optical isolators and optical filters used in optical amplifiers.
Passive optical devices for submarine cables, accounting for the majority of the world market share.
Source of competitiveness:
The source of competitiveness lies in production technology that can be consistently performed from manufacturing to assembly of optical device elements.
Established magneto-optical crystal manufacturing technology in 1986.
Succeeded in mass production of Faraday rotator as an applied product and an element having the property of rotating the polarization direction of light.
This provided a foothold for entering the long-distance optical communication device market.
Optical devices / products:
Since then
Optical isolator
Light attenuator
Optical filter etc.
I have continued to produce.
Underlying
As an elemental technology
Magneto-optic crystal manufacturing technology and
The point is that the thin film evaluation technology is used.

Familiarity with the properties of the material is a differentiating strategy for device performance.
The market for passive optical devices for submarine cables is estimated to be tens of billions of yen, which is by no means large.
on the other hand,
The technical requirements are extremely high
Continuing to meet the cutting-edge needs of ultra-high-speed, large-capacity communication
It will lead to the establishment of a foothold in the market.
