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

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 archi-

tectures.

Multiple Control Modes

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

matic 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 pre-

set threshold. Under automatic mode, the system can be set to be

Revertive or Non-revertive modes. Under Revertive mode, the sys-

tem 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

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 con-

figuration 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.
