Single-fiber bidirectional line protection
BD OLP, also known as BIDI OLP or single-fiber bidirectional 1+1 OLP, is an optical line protection method designed for situations where fiber resources are extremely limited. The system monitors the working optical fiber and a standby fiber in real time, detecting when the working path falls below a threshold. Designed for both cascaded and hub-and-spoke network topologies, the system ensures recovery from a single fiber cut in a ring. Traditional OLP protects 4-core optical fiber, but in many places, due to insufficient optical fiber resources, it is impossible to provide excessive optical fiber resources and optical line redundancy protection. Optical Line Protection System (OLP) is an automatic monitoring and protection system which is independent of telecommunication transmission.

Can single-mode fiber optic cables enable bidirectional communication
Yes, single-mode fiber can support full-duplex communication. Full-duplex communication means data can be transmitted and received simultaneously in both directions over a single fiber optic cable. Wavelength division multiplexing discriminates directions by assigning differing wavelengths for each, while fiber optic couplers combine signals of a shared wavelength by keeping back reflected light. BiDi optical modules can do this by utilizing full-duplex communication over a single fiber strand via two wavelengths. It is also known as bidirectional transmission, WDM-BiDi, or Bi-Directional Wavelength Division Multiplexing (BWDM). Moving to 100GbE does not have to mean a complete infrastructure overhaul.

Can a single-mode single-fiber transmission be bidirectional
Yes, single-mode fiber can support full-duplex communication. Full-duplex communication means data can be transmitted and received simultaneously in both directions over a single fiber optic cable. Simple design and low requirements. There are two ways to achieve this. In typical fiber-optic networks, two fiber strands. However, recently I have encountered several devices that utilize a single fiber while providing bidirectional communication. An example is this device which provides two zero-latency analog audio channels plus a 10/100 Ethernet port over. In practice, single-mode BiDi transceivers are particularly useful when fiber optic infrastructure is limited or cable capacity needs to be used efficiently, for example for networking data centers, metropolitan area networks (MAN), or fiber optic Internet connections such as FTTH/FFTO.
