s**** - r01. 2011.07.01 introduction features 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 a (1:1) optical protection system provides two diverse routes for the same link using optical switches at both ends. in case of working fber link failure, both ends switch to protection link. the (1:1) net- ready protection switches in 1x2 or 2x2 switch confgurations pro - vide this type of protection. the same switch fts 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 confgu - 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. ? 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
