High Speed Optical Bypass Protection Switch (OBP)

SKU: OBSP

Optical Bypass Protection Switching System (OBP) is deployed in each note to protect a cascaded or layered fiber optical network in which one equipment failure will disrupt the network integrity. In cases of power loss, software crash, or hardware failure, OBP automatically reroutes the transmission bypassing the malfunctioned equipment. This is achieved by inserting optical switches between the transmission fibers and real-time monitoring of the signal strength through the equipment, it automatically switches to the bypass connections when the signal power value is lower than a user-defined threshold. The unit integrates two detectors at the transmission and receiving lines, respectively. The automatic bypass switching signal level is user settable in the GUI. When the equipment is recovered, the transmission will be automatically restored. Our net-ready OBPs offer various reliable protection schemes against network failures. We uniquely provide fast optical switching to reduce data loss with three choices of optical switching speed: 100ns, 100 µs, 10 ms. Management of the OBP is performed using a Web GUI, reachable through the local Ethernet ports on the OBP system control card.
The order table includes a list of standard control interfaces. Additionally, we provide a list of commands to assist customer engineers in coding. For those who require it, we offer a code-writing service for customer interfaces at an additional charge.
Each switch driver includes a GUI for programming and a command set (API) so customers can develop their own control software. Python and LabVIEW interface libraries; integration support is available for a fee.
Due to inherent computer delays under Windows, response speed can be improved by using a Linux-based controller or executing stored switching sequences directly on the board. In this mode, the host computer simply issues start, pause, and repeat commands.
