Product Highlights
Hirundo's optical fiber torus is a multi-port non-reciprocal optical device in which light can only travel in one direction.If the signal is input through port 1, it is output through port 2. If the signal is input from port 2, it will be output from port 3. The output loss is very small. When the optical input is from port 2, the optical output from port 1 will lose a lot. Similarly, when the optical input is from port 3, the optical output from port 1 and 2 will lose a lot.Fiber ring is widely used in fiber laser, diff multiplexer, bidirectional pumping system, dispersion compensation device, fiber sensing, scientific research and other fields. Hirundo's optical fiber torus is available at 1310 nm and 1550nm, and has undergone rigorous quality inspection.
