| Media Converters Repeaters and Optimizers Datasheet Optical Self-Healing Switch Features FD 1+1 hot stand-by path protection - Point-to-point - Ring Link switchover times of 10 ms or less Protocol independence 1260 nm through 1620 nm wavelength range Maximum insertion loss of 5 dB per link Transparent network operation Overview The Fiber Driver(R) Optical Self-Healing Switch from MRV (EM316OSSH) makes creating a redundant optical link easier and more affordable than ever before. Designed to provide full path protection for mission critical networks, the module is capable of automatically switching between a primary and secondary (backup) link virtually instantaneously in the event of a fiber cut or transponder failure. As an all optical device performing no optical-electrical-optical (OEO) conversion, the EM316OSSH remains protocol independent. It accepts all wavelengths from 1260 nm to 1620 nm (including the 1310 nm and 1550 nm bands), making it suitable for virtually any application including WDM path protection. The module can provide 1+1 hot stand-by protection in resilient point-to-point or Optical Unidirectional Path Switched Ring (O-UPSR) deployments. Insertion loss is a maximum of 5 dB per pair of EM316OSSH modules. Application #1: Point to Point Redundant Link Primary Link sales@mrv.com Media Converters Repeaters and Optimizers Link switchover of 10 milliseconds or less is controlled by circuitry directly on the module. The switchover occurs so quickly that convergence protocols such as Spanning Tree or OSPF may never be triggered. The event remains transparent to both the network and the end user. The primary and secondary links are continuously monitored. The module can be set to automatically return to the primary link if it fails and then comes back online. In addition to loss of link detection , the EM316OSSH can be set to trigger a switchover based upon a lower optical power threshold of -5, -10, -15, -20, or -30 dBm. If the RX signal strength falls below the set threshold, the module automatically switches to the secondary link. The EM316OSSH may be configured through onboard DIP switch settings or from SNMP, Telnet, and local commands. A Fiber Driver Network Management Module installed in the same chassis paired with the Optical SelfHealing Switch is compatible with MegaVision Pro(R), the MRV network management system (NMS), or any SNMPenabled NMS. Management functions include alarm and trap control, primary and secondary path configuration, optical power threshold settings, module status check, and other useful parameters.
