s**** - r02. 2011.07.01 introduction features applications 1+1 NET-READY optical protection switch 1+1 NET-READY platform in todays network, protection switching at optical layer is a subject of great importance to the carriers. as a member of oplinks net- ready product family, oplinks NET-READY series protection switches offer various protection schemes against fber 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 fbers. in the event of a single link failure, an optical switch at the receiving end switches to the protection fber. the NET-READY protection switch in 1x2 switch confguration provides this type of protection. the same switch fts 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 - fguration 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. ? independent of data rate, format and wavelength ? highly confgurable to ft network applications ? simple, plug-and-play installation ? user-defnable thresholds and hysteresis ? user-selectable revertive and non-revertive modes ? latching optical switch ? remote confguration through snmp management interface ? front panel led and remote alarm ? optical fber protection for point-to-point transmission in any data format ? optical dedicated protection for fber ring
