1 Scope 1.1 Product definition This specification contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of a fully installed splice closure in order for it to be categorised as an EN standard product. 1.2 Operating environment The tests selected combined with the severity and duration is representative of outside plant for subterranean and/or aerial environments defined by: ETSI EN 300 019-1-4 class 8.1: underground locations (without earthquake requirement) EN 61753-1
category S: subterranean environment
category A: aerial environment 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5 Allowed fibre and cable types Although the performance tests are carried out on test samples with dispersion un-shifted singlemode fibre (see Annex A), the closure, once tested according to this product specification, will be also suited for other fibre types like dispersion shifted, non-zero dispersion shifted and multimode fibres.
This closure standard allows both singlemode and multimode fibre to be used and covers all EN standard optical fibre cables with their various fibre capacities, types and designs. This includes, but is not limited to, optical fibre cable standards EN 60794-2 (indoor), EN 60794-3 (outdoor). 2 Normative references The following referenced documents are indispensable for the application of this document.

The closures covered in the specification are those that are split at the cable entry ports. This allows for assembly over pre-installed cables or where there is no access to the cable end (i.e. uncut looped fibre). This is not to be confused with an optical closure for blowing cable or fibre. This comprises an access housing that allows the interconnection of cable ducts or tubes and is attached to the ends of the ducts or cables SIST EN 50411-2-3:2012

containing empty tubes. However, this document shall be used when air blown fibres are spliced inside this type of closure. The fibre management closure provides facilities for the environmental protection, housing for fibre management systems and sealing of input and output optical cables. In order to comply with the standard, the optical functionality, physical, geometrical and mechanical requirements are defined. The design of the closure housing shall allow the jointing of two or more cable ends in the following configurations or applications: Common base covering: (T) Track Joint configuration used on trunk cable, with minimum of 2 cable entries (S) Spur joint configuration used on local feeder cable with minimum of 3 cable entries (D) Distribution joints have 4 entry port configurations used typically on FTTH customer feed cable with minimum of 8, 18, 36, and 66 cable entry options. NOTE Cable entries can be more than one cable per cable entry port. The design of the distribution and spur joint closure housing shall allow the joining together of at least one pair of cables which are not at the end of a cable section, without cutting all fibres between both cable openings. This application is generally known as distribution joint or external node, but also called a mid-span closure or balloon splice.
It is desirable that the closure can be re-opened when necessary without interruption or disturbance of the traffic of the live circuits. 3.2 Closure overpressure safety Overpressure can build up in sealed closures due to temperature differentials, or due to atmospheric pressure changes over a period of time, to flash testing of the seals after installation, to incorrect installation techniques. Care should be taken when opening the closure. Provision shall be made to relieve any internal pressure differential prior to completely opening the closure.
For air blown fibre applications an overpressure release system is required for all sealed closures. 3.3 Cable seals Cable entry seal systems can be either, but not limited to: (H) Dedicated heat activated heat source, for example, electrical, infrared, hot air or flame • Thermo-shrinkable materials • Hot melt adhesives • Polyethylene injection welding (R) Dedicated cold applied • Mastic, tapes, pastes, potting compounds, gels and cold adhesives • O-rings, grommets, rubber shapes, pre-expanded tubing are cold processes (U) Combined heat activated and cold applied SIST EN 50411-2-3:2012

The fibre management closure allows for a physical housing structure that provides for optical cable fixing, sealing, anchoring, water and gas blocking, storage and routing up to the input and output fibres of the fibre management system. 3.4 Organiser system The organiser system provides means for routing, storing and protecting of fibres and fibre splices or other passive optical devices in a predetermined order, from one cable sheath opening to another. Fibre circuits may be separated to an appropriate separation level. This will limit the risk of interruption of traffic to those fibres that belong to the same group of circuits. • Single Circuit (SC) is a fibre management system that is a group of fibres providing one termination or service of 1 or 2 fibre(s). In this document a Single Circuit is considered to be a circuit of 2 fibres. • Single Element (SE) is a fibre management system that is a cable subassembly comprising one or more optical fibres inside a common covering e.g. tube or inside one groove of a grooved cable (slotted core cable). Single Elements provide more than one termination or circuit of typically 12 fibres. In this document a Single Element is considered to be a group of 12 fibres. • Single Ribbon (SR) is a fibre management system that is a cable subassembly comprising one optical ribbon. Single Ribbon is a group of fibres providing one termination or service of typically 4, 8 or 12 fibres. • Multiple Element (ME) is a fibre management system that provides all necessary equipment to connect a defined number of incoming and outgoing fibres/cables. It comprises storage and protection of fibres and interconnections in one splice tray for more than one Single Element. Typically splice tray capacities between 24 and 144 fibres. • Multiple Ribbon (MR) fibre management provides all necessary equipment to connect a defined number of incoming and outgoing fibre ribbons that are generally housed within a singe tube within the cable. This tube is typically fixed to the entry and exit ports of a splice tray. It comprises storage and protection of more than one single ribbon, but typically six or more fibre ribbons and their interconnections in a single splice tray for ribbons between 4 and 36 fibres, but typically 12 fibre ribbons. There are also many different names for this structure, e.g. mass storage or mass ribbons. Typically splice tray capacities are between 36 and 144 fibres. NOTE The families of organiser systems covered in this document are listed in Annex C. 3.5 Materials All materials that are likely to come in contact with personnel shall meet appropriate health and safety regulations. Closure and sealing materials shall be compatible with each other and with the materials of the cables. All components of the closure shall be resistant to solvents and degreasing agents that are typically used to clean and degrease fibres and cables. The effects of UV light on all exposed polymeric materials shall not affect product performance. The effects UV light shall be determined by measuring a suitable property (e.g. tensile strength) both before and after exposure. Metallic parts shall be resistant to the corrosive influences they may encounter during the lifetime of the product. 3.6 Colour and marking Marking/Identification of the ‘variant number’ (see Clause 4) to be on the product or packaging label along with the following: SIST EN 50411-2-3:2012

 identification of manufacturer;  manufacturing date code: year / month. The preferred colour for the outer closure material is black for polymeric materials. 4 Variants
