Polarisation insensitive optical circulators offer a cost effective, simple, passive and reliable method of increasing fibre capacity utilising existing installed fibre.

Optical circulators work by allowing bi-directional traffic over a single fibre, effectively doubling your network capacity. Optical circulators connected at either end of the fibre link present transmit and receive signal ports. Being fully compatible with standard single wavelength SFPs, our circulators can be seamlessly integrated into existing fibre networks.
