Ultra-low loss WDM is widely used in environment that needs low link budgets in communication system.

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.

The 1×2 DWDM device (3 ports) has channel spacing such as 100GHz, 200GHz, etc. HYC's 3-port DWDM devices use mature epoxy-free optical patch process with stable performance. Dense Wavelength Division Multiplexing has smaller channel interval and wider bands, which is suitable for long-distance and large-capacity transmission, such as metropolitan area network, backbone network, data center and other fields.

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.

PWDM is a combination of wavelength division multiplexing and photodetector, which is widely used in Triple Play, CATV, FTTH, fiber optic amplifiers, etc. Based on proven thin-film filtering technology, PWDM Photodetector has flat channel bandwidth and high isolation, low insertion and high environmental stability and reliability.
