Fibre optic interconnecting devices and passive components. Connector optical interfaces for single-mode fibres. Connection parameters of dispersion unshifted physically contacting fibres. Angled | Status: Current

1 Scope This part of IEC 61755 defines a set of prescribed conditions for a single-mode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss (RL) performance in a randomly mated pair of angled polished physically contacting (APC) fibres. The model uses a Gaussian distribution of light intensity over the specified mode field diameter (MFD) for determination of attenuation performance grades, based on MFD mismatch and the amount of lateral and angular fibre core offsets. Attenuation and RL performance grades are defined in IEC 61755‑1.
