Optical Link Protection Switch

1 DATA SHEET Optical Link Protection Switch Applications Product Overview Optical fiber protection for point-to-point transmission in any Link protection is designed to safeguard networks from failure. Failures in high-speed networks have always been a concern of utmost importance. A single fiber cut can lead to heavy losses of traffic and protection-switching techniques have been used as the key source to ensure survivability in such networks. Protection architectures like Path protection and Link protection safeguard the above-mentioned networks from different kinds of failures. In path protection, a backup path is used from the source to its destination to bypass the failure. In Link protection, the end nodes of the failed link initiate the protection. These nodes detect the fault and are responsible to initiate the protection mechanisms in order to detour the affected traffic from the failed link onto predetermined reserved paths. Other types of protection are channel-, segment- and p-cycle protection. data format. Optical dedicated protection for fiber ring. Features Independent of data rate, format and wavelength. Highly configurable to fit network applications. Simple, plug-and-play Installation. User-selectable revertive and non-revertive modes. Latching optical switch. Front panel LED and remote alarm.

2 Multiple Control Modes Optical link 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 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. power level detected and the preset threshold. Under automatic mode, the system can be set to be Application Solutions Link Protection in the Optical Transport Layer Two fibers are used as working fibers and the other two are used as protection fibers, to be utilized in the case of a failure. Common occasions Optical link 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 optical link protection switch in 1X2 switch configuration provides this type of protection. The same switch fits both point-to-point and dedicated protection switch ring architectures.
