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 NETReady product family, Oplink’s NET-Ready series protection switches
offer various protection schemes against fiber cuts and network failures.
(1+1) Protection
With (1+1) optical protection, service is protected from link failures,
using an optical splitter to bridge the optical signal and dual feed it
on diversely routed working and protection fibers. In the event of a
single link failure, an optical switch at the receiving end switches to
the protection fiber. The NET-Ready protection switch in 1x2 switch
configuration provides this type of protection. The same switch fits
both point-to-point and dedicated protection switching ring architectures.
Multiple Control Modes
NET-Ready (1+1) protection switch provides both Manual and Automatic switching mode. In Manual mode, the system switches optical
path only based on the commands from user. In the Automatic mode,
the system switches based on the power level detected and the preset threshold. Under automatic mode, the system can be set to be
Revertive or Non-revertive modes. Under Revertive mode, the system switches back to the working path automatically after the fault
condition is cleared. Under Non-revertive mode, the system does
not switch back.
Programmable Threshold and Hysteresis
Features
 Independent of data rate, format and
wavelength
 Highly configurable to fit network applications
 Simple, Plug-and-play Installation
 User-definable thresholds and hysteresis
 User-selectable revertive and non-revertive
modes
 Latching optical switch
 Remote configuration through SNMP
management interface
 Front panel LED and remote alarm
Alarm and switching threshold and hysteresis are programmable remotely or locally.
Remote Management and Alarm
NET-Ready (1+1) protection switch provides remote system configuration 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.
Applications
 Optical fiber protection for point-to-point
transmission in any data format
 Optical dedicated protection for fiber ring
