Multifunction relay-to-relay fiber optic control and monitoring

The Fidra is a fiber-optic switch designed to monitor, reroute, repeat, boost and disable up to 3 fiber optic communication pairs. Utilizing industry standard SFP modules allows Fidra to support various optical communications including single/multimode, LED/Laser as well as multiple wavelengths. Common applications for Fidra include:

1. Communications disable
2. Fiber optic path routing
3. Wavelength and fiber type conversion
4. Level monitoring
5. Local and remote loopback testing

The Fidra was designed for applications such as protective relaying and other environments where substation hardened equipment is required. It resides in line with equipment utilizing fiber optic communications. It allows for testing and maintenance without the need to remove and reroute fiber cables, eliminating costly fiber damage and ruining components caused by improper handling.

The Fidra is programmable to route any receive signal to any of the three transmitters. All routing is performed at the physical layer (PHY layer), therefore, Fidra communications are transparent regardless of the brand of communications equipment used. No protocol support is required and only microseconds of delay are added to the signal propagation time, making it ideal for differential relaying applications. Testing and monitoring are streamlined while providing safety to the technician and ease of implementation to the system.
