Variable Optical Attenuator

1 ~ 50dB attenuation range

Planar Lightwave Circuit Splitter

The Planar Lightwave Splitter is based on unique silica glass waveguide process, it features excellent optical performance with low insertion loss, low PDL, high return loss over a wide wavelength range from 1260nm to 1620nm. It is used in FTTx Systems, LAN, WAN and Metro Networks, Analog Passive Optical Networks, CATV Networks and other applications in fibre-optics systems.

Faraday Mirror Series

The Faraday Mirror is a passive device that provides 90 degree rotation without regard to the polarisation state of the input light. The FM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in EDFA, DWDM systems, CATV systems, fibre laser and fibre instruments to minimize the polarisation effect.

Polarisation Insensitive Mini Circulator

The mini fibre optic circulator is a compact, high performance lightwave component that transmits the incoming signal from port 1 to port 2, and another incoming signal from port 2 to port 3 simultaneously. The component provides high isolation, low insertion loss, low PDL, low PMD and excellent environmental stability. It is widely used in combination with fibre gratings and other reflective components in DWDM systems, high speed systems and bi-direction communication systems.
