Basic Functions

Optical Isolator (Isolator):

Realise unidirectional transmission of optical signals and prevent reflected light from returning to the light source.

Tap Coupler:

Distribute the input optical signal to the main output port and monitoring port according to a certain ratio.

Wavelength Division Multiplexer (WDM):

Multiplexes (combines) and demultiplexes (separates) signals of multiple wavelengths.

Applications

Optical communication systems:

For signal isolation, monitoring and multi-wavelength transmission in fibre optic networks.

Fibre Lasers:

Protects lasers from reflected light interference while enabling multi-wavelength output.

Optical Sensing Systems:

For signal isolation and multi-wavelength monitoring in distributed fibre optic sensing.

Test and Measurement:

Signal isolation, spectroscopy and wavelength separation in optical test equipment.

Data Centres:

For signal management and monitoring in high-speed optical modules.
