| Descriptions |
The PM Combiner enables the efficient combination of two orthogonally polarised sources of light such that they are output through the same, single fibre output. In optical amplifiers this provides a doubling of pump power whilst ensuring pump redundancy should a pump failure occur. Applications include high power optical amplifiers and undersea systems. |
