Features of the CSW series

Highly reliable, high-performance optical switch function
Optical switch function equivalent to high-end models

This model was developed based on the technology of the high-end model NSW series, which has been used in IX/ISP, etc., and has the same optical switch function as the high-end model.

compact and lightweight
Can be installed in places where installation space is limited or in places other than racks

It can also be installed in locations where installation space is limited or in locations other than racks.

*It is also possible to mount it on a 19-inch rack using the standard rack-mount brackets.


Low price
Low price realized by optimizing for customer's application

Low cost is achieved by optimizing for customers with specific applications, such as a single power supply configuration with low power consumption and improved reliability, and limiting the number of optical switches installed to one channel.
It is ideal for path redundancy that does not require multiple optical switches and for use in small-scale networks.
