Classic Networking Applications
The optical multiplexer and demultiplexer equipment are widely used to address the issue of insufficient optical cable resources in transmission. Using Thin Film Filter (TFF) technology and Planar Lightwave Circuit (PLC) technology, multiple optical carrier signals are multiplexed onto a single optical fiber for transparent transmission. This supports dual-fiber bidirectional, single-fiber bidirectional, and single-fiber single-direction applications.Application 1: Dual-Fiber Bidirectional Multiple optical carrier signals are multiplexed onto two-core optical fiber for transmission, utilizing the two-core optical fiber to transmit multiple services, significantly reducing investment costs and saving time in optical cable deployment.
Application 2: Single-Fiber Bidirectional Using the reversible property of light, multiple optical carrier signals are multiplexed onto a single-core optical fiber for transmission, utilizing the single-core optical fiber to transmit multiple services, significantly reducing investment costs and saving time in optical cable deployment.
Application 3: Smooth Upgrade Smooth upgrade involves connecting another multiplexer/demultiplexer through the expansion interface in the original wavelength division system to achieve smooth upgrade and expansion without affecting the original services.
