Descriptions

Fast switching function

Quick (less than 10ms) switchover to spare in case of OLT line card failure

High-speed (Tpy.5ms or less) switching by optical switches makes it possible to provide services with minimal downtime for users.
The optical switch uses a highly reliable mechanical type that is used in IX, etc., so even in the unlikely event of a failure, optical communication is ensured.

Automatic/remote switching function

Automatic/remote switching function reduces the cost of emergency response

Based on line card failure information from OLT, etc., automatic switching to a spare line card is possible. In addition, since maintenance, installation work, and obstacle relocation can be switched remotely, it is possible to reduce rush costs.

Reduced spare machine cost.One spare machine

Can be expanded to up to 64, reducing spare machine cost.

The N+1 redundant configuration can reduce the redundancy cost compared to the 1 working: 1 spare configuration.Furthermore, assuming that the frequency of simultaneous failures is not necessarily high for line cards, the number of redundant lines can be expanded to a maximum of 64 in order to minimize the number of spare line cards, thereby maximizing the reduction in redundancy costs.
