We have investigated the polarisation-maintenance capability of 50µm graded-index multimode fibres (MMF) in the C-band. Using both circularly, and linearly polarisation-multiplexed signals centre-launched into the MMF, we found that orthogonality is sufficiently maintained in both cases to yield typically 10dB optical isolation between the channels. Using orthogonally circular polarisation-multiplexed signals, we show experimentally that two 3 and 5Gb/s data channels may be transmitted error free over 50µm multimode fibre spans up to 3km in length.
