The 3-port CWDM device is mainly used in the passive wavelength division multiplexing module. It is a kind of wavelength division multiplexing technology based on TFF (thin film filter). It has a variety of package sizes and wavelength options. It consists of three ports: COM, Pass and Reflect. The wavelength range meets the ITU-T G.694.2 standard. It can Mux, Demux or add-drop multiplexing different light in WDM system. Signals, as well as increasing signal transmission speed and communication capacity, are widely used in telecommunications, radio and television, enterprise network, campus network and other fields.

Three-port DWDM device is mainly used in passive wavelength division multiplexing module. It is a kind of wavelength division multiplexing technology based on TFF (thin film filter). It has a variety of package sizes and wavelength options. It consists of three ports: COM, Pass and Reflect. Compared with CWDM, DWDM has 100 GHz, 200 GHz channel spacing, which greatly increases the number of working wavelength, thus greatly increases the signal transmission speed and communication capacity. It is suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes, and is widely used in telecommunications, radio and television, 5G and other fields.

MWDM plug-in module is based on TFF(thin film filter) wavelength division multiplexing technology which has a variety of options of wavelength and link structure. It MUXes optical signals of different wavelengths to a single optical fiber, or DEMUXes the signals in the optical fiber into signals to different wavelengths at the receiving end. It is one of the practical application for 5G fronthaul.

The DWDM LGX module of HYC is a wavelength division multiplexing technology based on TFF (thin film filter), which has a variety of package sizes and wavelength options; DWDM has 100 GHz, 200 GHz channel spacing, suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes; Under the current 5G environment, HYC develop a series of central office terminal (COT) and remote terminal (RT) products base on the market demand. It can increase the 4G extension (EXT) port, OTDR port and etc. according to customer requirements.

The 6-port DWDM device of HYC is mainly used for passive WDM module of dual fiber transmission. It is a WDM technology based on TFF (thin film filter), which has a variety of packaging sizes and wavelength selection, DWDM has channel spacing of 100 GHz and 200 GHz; A 6-port DWDM is equivalent to two 3-port products, It is suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes, and is widely used in telecommunications, radio and television, 5G and other fields.

3-port FWDM devices are used in passive optical WDM module; They can multiplex or demultiplex different optical signals in wavelength division multiplexing system, and increase the signal transmission speed and communication capacity.
