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.

• Operating in one or both of the following frequency ranges:
- 9 000 MHz to 9 200 MHz and 9 300 MHz to 9 500 MHz utilizing modulated or unmodulated pulses.
• Transmitter Peak Envelope Power up to 100 kW.
• The transceiver-antenna connection is using a hollow metallic rectangular waveguide.
• The antenna is rotating, waveguide-based and passive.
• At the transceiver output an RF-circulator is used.
NOTE 1: Since transceiver and antenna are hollow metallic rectangular waveguide based the frequency range for
measurements that needs to be addressed covers 6,56 GHz to 26 GHz. The lower limit of this frequency
range is obtained as cut-off frequency of the combination of WR112/R84 taper section and a WR90/R100
Waveguide IEC 60153-2 [i.3]. The upper limit corresponds to the upper limit stated in table 1 of ERC
Recommendation 74-01 [2].
NOTE 2: Since at the transceiver output an RF circulator is used, it is assumed that the transceiver characteristics
remain independent from the antenna.
NOTE 3: Aeronautical Surface Movement Radars covered by the present document are expected to use the bands
9 000 MHz to 9 200 MHz and/or 9 300 MHz to 9 500 MHz. According article 5 of the ITU Radio
Regulations [3] the band 9 000 MHz to 9 200 MHz is allocated to the Aeronautical Radionavigation
Service on a primary basis and the band 9 300 MHz to 9 500 MHz is allocated to the Radionavigation
Service on a primary basis.
NOTE 4: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
