Features

High isolation: Reduces interference between wavelengths.

Low insertion loss: Ensures high signal transmission efficiency.

Three-port design: Includes one input port and two output ports, or vice versa.

Wavelength Splitting: Separates or combines optical signals of different wavelengths.

CWDM technology: Supports Coarse Wavelength Division Multiplexing (CWDM), typically covering 18 wavelengths (1270nm to 1610nm).

Applications

CATV system: Separate or merge signals of different channels.

Data Centre: Optimise internal data transmission and improve network efficiency.

Test and Measurement: For testing and monitoring of optical communication equipment.

Telecommunication Network: Expand transmission capacity in backbone and metro networks.

Optical fibre communication: for metropolitan area networks and access networks to improve fibre optic bandwidth utilisation.
