1:1 NET-Ready Optical Protection

Switch

1:1 Net-Ready Platform

In today’s network, protection switching at optical layer is a subject

of great importance to the carriers. As a member of Oplink’s NET-

Ready product family, Oplink’s NET-Ready series protection switches

offer various protection schemes against fiber cuts and network fail-

ures.

(1:1) Protection

A (1:1) optical protection system provides two diverse routes for

the same link using optical switches at both ends. In case of working

fiber link failure, both ends switch to protection link.The (1:1) NET-

Ready protection switches in 1x2 or 2x2 switch configurations pro-

vide this type of protection.The same switch fits both point-to-point

and shared protection switching ring architectures.Multiple Control

Modes

Multiple Control Modes

NET-Ready (1:1) protection switch provides both Manual and Auto-

matic switching modes. In Manual mode, the system switches only

based on commands from user. In Automatic mode, system switches

based on power level detected and pre-set threshold. Automatic

mode has two sub-modes: Revertive and Non-revertive. Under Re-

vertive mode, system switches back to working path automatically

after fault condition is cleared. Revertive mode needs an external

signaling channel to realize. Under Non-revertive mode, the system

stays at protection link and switch back only when current protec-

tion link has failure.

Programmable Threshold and Hysteresis

Alarm and switching threshold and hysteresis are programmable re-

motely or locally.

Remote Management and Alarm

NET-Ready (1:1) protection switch provides remote system configu-

ration and management through SNMP. Web GUI and CLI is also

provided for user to manage the system locally via Ethernet or craft

RS-232 interface respectively.
