BS EN 61755 is a series on fibre optic connector optical interfaces. Fibre optic connector optical interfaces join optical fibres and enable quicker connection and disconnection than splicing. BS EN 61755-2-1 defines a set of prescribed conditions that must be maintained in order to satisfy the requirements of attenuation and return loss performance in a randomly mated pair of fibres considering a beam with a Gaussian distribution of light intensity over the considered MFD. Performance grades are classified into four categories for attenuation and return loss measurements.
BS EN 61755-2-1 on fibre optic connector optical interfaces is useful for:
The connectors mechanically couple and align the cores of fibres so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibres. Proposed performance grades for PC polished connectors are given in BS EN 61755-2-1. The performance grades based on return loss are for single mode non-angled connectors only. Performance grades for APC connectors are defined separately in IEC 61755-2-2.
BS EN 61755-2-1 give the criteria for meeting the performance grades listed. The parameters chosen for the criteria definition are based on the degree of significance in affecting the performance under test. The criteria selected are based on the theoretical model presented in BS EN 61755-2-1. Using BS EN 61755-2-1 you can define a set of prescribed conditions that must be maintained in order to satisfy the requirements of attenuation and return loss performance in a randomly mated pair of fibres considering a beam with a Gaussian distribution of light intensity over the considered MFD.
