1:1 NET-Ready Optical Protection
Switch
1:1 Net-Ready Platform
Introduction
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.
