DWDM devices are mainly used in passive wavelength division multiplexing system module products, It has the characteristics of low insertion loss, low polarization, high channel isolation and high environmental stability and reliability. It is suitable for long-distance, large-capacity long-distance trunk network or ultra-large capacity MAN core nodes. DWDM is widely used in metropolitan area network, telecommunications 5G, backbone network, data center and other fields.

The 1x2 CWDM device (3 ports) is a kind of wavelength division multiplexing technology based on TFF(Thin Film Filter). HYC's 3-port CWDM devices use mature epoxy-free optical patch process with stable performance. All products meet the GR-1209 & GR-1221-Core standards, and meet the 168-hour PCT reliability test requirements.

HYC's LAN WDM module is based on TFF (Thin Film Filter) wavelength division multiplexing technology, which adopts a free space structure package method. Its package size is greatly reduced compared with traditional passive modules, and the insertion loss is lower. It has better consistency and meets industrial standards. It is suitable for 40G&100G CFP optical modules and is widely used in data centers, cloud computing, metropolitan area networks, etc.

HYC's 3-port FWDM devices use mature epoxy-free optical patch process with stable performance. All products meet the GR-1209 & GR-1221-Core standards and meet the 168-hour PCT reliability test requirements.

The CCWDM (Compact CWDM) MUX/DEMUX is a multi-channel CWDM device with compact package designed for cost-effective multi-wavelength CWDM network applications. It is based on the Thin Film Filter (TFF) technology and and free-space technology platform.

Reflective WDM(Wavelength Division Multiplexing) adopts reflected type structure, with all port’s fiber on one side of the body, which can maximum reduce fiber coiling space. Based on thin film filter technology and epoxy-free optical path technology, HYC’s reflective WDM has a high transmission isolation of >50dB.

The CWDM MUX&DEMUX ABS 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; It MUX the optical signals of different wavelengths to a single optical fiber for transmission, and the receiving end uses the DEMUX to decompose the signals in the optical fiber into signals of different wavelengths; Because of the advantages of CWDM, such as wide band and low requirement for system equipment, it has occupied an important position in the access layer of MAN, and is widely used in telecommunications, enterprise network, campus network and other fields.
