About Us

Perfect for use as a backbone line between data centers. This is a high-capacity leased line service with hitless switching and supporting SDH/SONET/Ethernet interfaces and bandwidth ranging from 50Mbps to 40Gbps.

The GIGASTREAM TypeG Gigaway Service is a highly reliable, high-quality, completely guaranteed bandwidth leased line service. We have also provided a variety of items for each of the three types - SDH/SONET, wavelength (Ethernet) and bandwidth selection (Ethernet) - to provide fast and flexible responses even for future bandwidth increases and line additions.
The GIGASTREAM TypeG Gigaway Service is a point-to-point high-speed, broadband leased line service. It is possible to economically deploy highly reliable, high-quality networks such as using different paths for redundancy of relay transmission paths, automatic switchover functions when outages occur and completely guaranteed bandwidth. It is optimal for real-time backup lines for high-capacity LAN connections and disaster recovery systems.

Example of the creation of a flexible corporate network
As organizational mergers and departmental integration become more frequent, there are bound to be more opportunities to review corporate networks. With GIGASTREAM TypeG, you can build flexible networks using redundant hub architecture (2.4G/10G ring) that does not affect lines to other offices when adding and consolidating offices or increasing speed. Of course, we offer excellent reliability through redundant end-to-end lines using different paths including access lines.
