Three-port optical fiber torus

1
An optical fiber torus is a one-way device that directs optical signals from one port to another in one direction at a time. Although the optical signal can be redirected as needed, it must pass through each port in sequence (that is, it must pass through ports 1 and 2 in sequence before reaching port 3). In addition, fiber optic circulators can be used to achieve bidirectional transmission on a single fiber.

Three-port optical fiber torus is a one-way device that directs optical signals from one port to another in one direction at a time. Although the optical signal can be redirected as needed, it must pass through each port in sequence (that is, it must pass through ports 1 and 2 in sequence before reaching port 3). In addition,Three-port optical fiber torus can be used to achieve bidirectional transmission on a single fiber.
The main feature of is Three-port optical fiber torusthat bidirectional optical signal transmission can be realized on a single fiber. The signal transmission direction of the Three-port optical fiber torus is irreversible. The optical signal can only be guided from one port to another in one direction at a time. Although the optical signal can be redirected, it must pass through the port in one direction in sequence. For example,Three-port optical fiber torus optical signal must be propagated from port 1 to port 2 and then to port 3.
Three-port fiber optic torus transmission
Three-port fiber optic torus can be classified by the number of ports, or by polarization correlation. Three-port fiber optic torus can be divided into three ports, four ports and six ports. Port 3 and port 4 are common types. According to polarization, it can be divided into polarization-preserving Three-port optical fiber torus and polarization-independent Three-port fiber optic torus (PI). Polarization-maintaining fiber toroids are commonly used in polarization-maintaining applications, such as 40Gbps high-speed systems or Raman pumping applications, two-way amplifiers and dispersion compensators (DCM). Polarization-independent fiber torus, together with fiber Bragg grating and other reflective devices, are widely used in coarse wavelength division multiplexing (DWDM) systems, high speed systems and bidirectional communication systems.
Three-port optical fiber torus are commonly used in passive optical networks, (wavelength division multiplexing)WDM networks, polarization mode dispersion, dispersion compensation, optical plug-in modules (OADM), Three-port fiber optic torus, optical time domain reflectometry (OTDR)) and Three-port fiber optic torus sensing applications.
