1.1   General
Part 001 of EN 4533 examines the termination of optical fibre cables used in aerospace applications. Termination is the act of installing an optical terminus onto the end of a buffered fibre or fibre optic cable. It encompasses several sequential procedures or practices. Although termini will have specific termination procedures, many share common elements and these are discussed in this document. Termination is required to form an optical link between any two network or system components or to join fibre optic links together.
The fibre optic terminus features a precision ferrule with a tight tolerance central bore hole to accommodate the optical fibre (suitably bonded in place and highly polished). Accurate alignment with another (mating) terminus will be provided within the interconnect (or connector) alignment mechanism. As well as single fibre ferrules, it is noted that multi-fibre ferrules exist (e.g. the MT ferrule) and these will also be discussed in this part of the handbook.
Another technology used to connect 2 fibres is the expanded beam. 2 ball lenses are used to expand, collimate and then refocus the light from and to fibres. Contacts are not mated together. It helps reducing the wear between 2 contacts and allows more mating cycles. This technology is less sensitive to misalignments and dust. Losses are remaining more stable than butt joint contact even if the nominal loss is higher.
A Note on Terminology
Current terminology in the aerospace fibre optics community refers to an optical terminus or termini. The term optical contact may be seen in some documents and has a similar meaning. However, the term contact is now generally reserved for electrical interconnection pins. The optical terminus (or termini) is housed within an interconnect (connector is an equivalent term). Interconnects can be single-way or multi-way. The interconnect or connector will generally house the alignment mechanism for the optical termini (usually a precision split-C sleeve made of ceramic or metal). The reader should be aware of these different terms.
An optical link can be classified as a length of fibre optic cable terminated at both ends with fibre optic termini. The optical link provides the transmission line between any two components via the optical termini which are typically housed within an interconnecting device (typically a connector) with tight tolerancing within the alignment mechanisms to ensure a low loss light transmission.
Part 001 will explain the need for high integrity terminations, provide an insight into component selection issues and suggests best practice when terminating fibres into termini for high integrity applications. A detailed review of the termination process can be found in section 4 of this part and is organised in line with the sequence of a typical termination procedure.
The vast number of cable constructions and connectors available make defining a single termination instruction that is applicable to all combinations very difficult. Therefore, this handbook concentrates on the common features of most termination practices and defining best practice for current to near future applications of fibre optics on aircraft. This has limited the studies within this part to currently available ‘avionic’ silica fibre cables and adhesive filled butt-coupled type connectors. Many of the principles described however would still be applicable for other termination techniques. Other types of termination are considered further in the repair part of this handbook.
It is noted that the adhesive based pot-and-polish process is applicable to the majority of single-way fibre optic interconnects connectors and termini for multi-way interconnects and connectors. They share this commonality.

The purpose of this MOAA standard is to define a set of open architecture standards,
concepts & guidelines for Advanced Avionics Architectures (A3).
The three main goals for the MOAA Standards are:
— Reduced life cycle costs,
— Improved mission performance,
— Improved operational performance.
The MOAA standards are organised as a set of documents including:
— A set of agreed standards that describe, using a top down approach, the Architecture overview to all
interfaces required to implement the core within avionics system,
— The guidelines for system implementation through application of the standards.
This standard details the functionality and principle interfaces of an EN 4660 compliant network to
ensure the interoperability of Common Functional Modules and design guidelines to assist in
implementation of such a network.
The purpose of this standard is to establish by means of well defined interfaces and functionality, a
network design that is technology transparent and that is open to a multi-vendor market. Therefore,
specific data communication network topology, protocols and technologies are not identified in this
document.
Although the physical organisation and implementation of the network shall remain the System
Designers choice, in accordance with the best use of the current technology, it is necessary to define
interfaces and parameter sets in order to achieve a logical definition of the network with a defined
functionality. This definition includes:
— The generic functionality applicable to all networks.
— The logical interfaces to the Operating System and Module Support Layers.
— Optionally the physical interfaces to the Common Functional Modules (CFM).
This document identifies the principle interfaces for the Network, in Clause 4, and where appropriate,
provides requirements on network parameters to be defined.

This document specifies the characteristics of UV laser printable jacket, silver plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer (XLETFE) family for use in the on-board electrical systems of aircraft operating at temperatures between  65 °C and 150 °C, operating at voltages not exceeding 600 V rms at sea level and frequencies not exceeding 2 000 Hz. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user.
These cables are suitable for airframe use without additional protection. In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence.

This document specifies the characteristics of UV laser printable jacket, tin plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer (XLETFE) family for use in the on board electrical systems of aircraft operating at temperatures between - 65 °C and 135 °C, operating at voltages not exceeding 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user. These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the cores may need additional protection. In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence.

This European standard establishes uniform requirements for Packaging for the Common Functional
Modules (CFM) within an Integrated Modular Avionic (IMA) system. It comprises the module physical
properties and the Module Physical Interface (MPI) definitions together with guidelines for IMA rack
and the operational environment.
The characteristics addressed by the Packaging Standard are:
Interchangeability:
 For a given cooling method all modules conforming to the packaging standard will function
correctly when inserted into any rack slot conforming to the standard for the cooling method.
 All modules conforming to the Module Physical Interface (MPI) definitions for connector, IED and
cooling interface will function correctly when inserted into any rack slot conforming to the same
MPI definition.
Maintainability:
 All modules are easily removable at first line.
 No special tools required at first line.
 No manual adjustment is necessary when installing modules. No tool is required for installation or
removal of the modules.
 Mechanical keying is provided that prevents insertion of a module into a rack slot that may cause
an unsafe condition.
The Module Physical Interface definition, contained within this standard, does not include the
properties of the signalling used in the optical interface (e. g. wavelength). These are covered in
EN 4660-003.
