Features of the ESW series
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.
予備機コスト低減
1台の予備に対して最大64まで拡張可能、予備機コスト低減
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.
Supports high-density, space-saving OLT
(16 + 1) x 2/4 mode supports 2/4 port type line cards
The 2/4-port type line card, which aims to increase the rack storage rate and reduce the unit cost per port, achieves multi-port line card redundancy by interlocking 16+1 optical switches. Based on the sales record of linking up to 8 devices and linking up to 256 optical switches, it also supports multi-port type line cards.
