IdealPhotonics' dual-wavelength single-mode WDM is a compact wavelength division multiplexing technology based on single-mode fiber. Its core function is to achieve bidirectional communication or dual-channel data separation by independently transmitting two specific wavelengths (such as 1310 nm and 1550 nm) of optical signals within the same fiber.Based on single-mode fiber, the dual-wavelength orthogonal multiplexing technology achieves low crosstalk, high-efficiency bidirectional transmission, and combines the advantages of compact structure and cost optimization.
