The coarse wavelength division multiplexer is based on the thin film filter technology and is mainly applied to the metro network convergence and access layer, which can build networks and conduct services in a short time. Because of its low cost, low power consumption, small size and many other advantages, the coarse wavelength division multiplexer is a low-cost, high-performance transmission solution that has been widely used in metropolitan area network transmission.
