IEC 61755-2-4:2015

Fibre optic interconnecting devices and passive components - Connector optical interfaces - Part 2-4: Connection parameters of non-dispersion shifted single-mode physically contacting fibres - Non-angled for reference connection applications

IEC 61755-2-4:2015 defines a set of prescribed conditions that should be maintained in order to satisfy the requirements of non-angled polished reference connections. The prescribed conditions include dimensional limits and optical fibre requirements of the optical interface to meet specific requirements for reference connection (plugs and adaptors) used for attenuation measurements. Two different grades for reference connections are defined in this standard. The use of each of these grades depends on the application and on the targeted attenuation measurement uncertainty. The model uses a Gaussian distribution of light intensity over the specified restricted mode field diameter (MFD) range. This standard is intended to be used for shipping and acceptance inspections. The reference connector plug is specified for B1.1, B1.3 and B6 fibres as specified in IEC 60793-2-50. The use of the reference connector plug would not be recommended where classification of fibre is difficult, for example construction and maintenance of cable plant. Keywords: non-angled polished reference connections, plugs and adaptors, attenuation measurements

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

• mandatory clauses to satisfy,
• non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.
