CWDM passive WDM equipment Product Overview passive CWDM multiplexer and demultiplexer using advanced thin film filter technology to support the use of lasers without temperature control. These products support a variety of standard CWDM channels. All passive devices are very stable, indoor and outdoor adapt to different situations. The device supports different environments rack mounting, wall mounting and so on. CWDM passive devices are connected to a low-loss technology to ensure the lowest insertion loss. Products 1. Independent passive devices The product packaging machine cassette, can be placed on a desktop, wall, fiber transfer boxes and other environment that supports 20nm intervals between 1270nm ~ 1610nm wavelength multiplexing.
