Designed and manufactured by Oz Optics, they transmit rays in only one polarisation, blocking light in unwanted polarisation states. They feature extinction ratios as high as 30 dB, insertion losses as low as 0.6 dB and return losses of-60 dB. The polarisers operate over the entire C-, L-and S-bands, and are also available for other wavelengths. The input and output fibres can be single-mode or polarisation-maintaining fibres and can be custom-terminated.
