1.1 Product definition This European Standard contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall box, in order for it to be categorized as an EN standard product. The typical configuration is splicing of incoming fibres to optional splitters and/or to pigtails, connecting pigtails plugs on one side to patchcord plugs on the other side, using adapters. A wall box is a protective housing containing a fibre management system with splice trays of various fibre separation levels and connector mounting plates. The wall box may contain one or more of the following: storage and routing of fibre and cable; - uncut fibre cable storage; - splice trays; - adaptors and connectors; - passive optical devices (optical splitters or WDM). A wall box can be installed on a vertical indoor or outdoor surface above ground level. If the wall box is required to be relocatable with cables attached, the following additional tests shall be performed: - cable bending; - cable torsion. This document specifies the number of splice trays and splice/connector capacity for each fibre separation level. The maximum capacity is 144 connectors and splice. For housings with a higher number of splices and connectors the document prEN 50411 4 1 (Cabinets) should be used. Wall boxes for fibre splices only are covered in EN 50411 3 1:2012. 1.2 Operating environment The tests selected, combined with the severity and duration, and are representative of indoor and outside plant for above ground environments defined by: EN 61753 1 Ed2 (20xx): - category C: Controlled (indoor) environment; - category A: Aerial (above ground) environment. 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this European Standard does not guarantee the reliability of the product. This should be predicted using a recognized reliability assessment programme. 1.4 Quality assurance Compliance with this European Standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognized quality assurance programme. 1.5 Allowed fibre and cable types This wall box standard accommodates EN 60793 2 50 single-mode fibres and EN 60793 2 10 A1a and A1b multimode fibres and all EN 60794 series optical fibre cables with various fibre capacities, types and designs as long as fitting in the cabinet does not contravene the fibre or cable minimum bend radius.

IEC 61300-2-46:2019 is available as IEC 61300-2-46:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61300-2-46:2019 describes a test to determine the suitability of a fibre optic device to withstand the environmental condition of high humidity and change of temperature which can occur in actual use, storage and/or transport. The test is primarily intended to determine the suitability of fibre optic components under conditions of high humidity – combined with cyclic temperature changes and, in general, producing condensation on the surface of the device under test (DUT). Absorption of moisture can result in swelling that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties can also occur. Although not necessarily intended as a simulated tropical test, this test can, nevertheless, be useful in determining moisture absorption of insulating or covering materials. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) complete revision to harmonize with IEC 60068-2-30; b) addition of detail description Clause 4, General description; c) addition of detail description Clause 5, Apparatus; d) addition of detail description Clause 6, Procedure.

1.1 Product definition This standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements for an assembled single mode cord with cylindrical ferruled connectors to meet in order for it to be categorized as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 4.5 and Clause 5. 1.2 Intermateability of the plugs Although all products conforming to the requirements of this standard are meant to intermate, the resulting level of random attenuation performance will only be expected in accordance with Table 1. The intention is that this will be true irrespective of the manufacturing source(s) of the product. When intermating plug variants having different attenuation grades as specified in EN 61755 1, the resulting level of attenuation cannot be ensured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in a grade C level of random attenuation performance. Table 1 — Ensured level of random attenuation Plug variant / Attenuation grade Plug 2 C B Plug 1 C C C B C B 1.3 Operating environment The tests selected combined with the severities and durations are representative of an EN 61753 1 Category C environment. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this standard does not guarantee the reliability of the product.

1.1 Product definition This European Standard specifies the dimensional, optical, mechanical and environmental performance requirements of a Terminal Equipment Boxes for the FTTX networks. The Terminal Equipment Box will house the ONT/CPE (electronics) and it protects the optical fibres, splices and connectors from direct contact with the user. Optionally it can contain the network test interface, the power supply and the batteries. The performance of the electronics, power supply or batteries are not part of this document. These are covered by another EN document, EN 50700. This specification contains the initial, start of life optical, mechanical and environmental performance requirements of the optical fibre termination in a Terminal Equipment Box, in order for it to be categorized as an EN standard product. 1.2 Operating environment The tests selected combined with the severity and duration is representative of indoor and outside plant for above ground environments defined by: EN 61753-1 Category C Controlled 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 All EN 60793-2-50 fibres can be stored in the Terminal Equipment Box with a minimum storage radius of 20 mm (up to a length of maximum 2 m). Smaller storage radii down to 15 mm are possible with the EN 60793-2-50 B6A fibre types, but in this case the reduction in mechanical reliability should be taken into account (see Annex A).

1.1 Product definition This European Standard covers wall outlets for up to 4 SC foot-print adapters. Various connector types (e.g. SC, LC) can be implemented as long as the adapter fits in the SC foot-print dimensions. A Wall Outlet is the passive end connection point of a fixed Single Mode fibre based FTTH network to the flexible network of service unit (CPE, ONT) indoor. Products defined by IEV 442-08-02 or IEV 723-09-22 can be considered as Wall Outlets. SI or ENTI are not part of this wall outlet specification. This specification also covers the possibility of using hybrid (fibre/copper) wall outlets with 1 RJ-45 footprint. Performance of copper cabling and connectivity is not in the scope of this document, but should be verified in line with EN 50346. Wall outlets are placed in end user premises by installers and the contents are not intended to be user accessible. Wall outlets may be mounted using a number of techniques: surface mounted on a wall, patress boxes, trunking or raceway; flush mounted or between cable trunking. Cable entry points vary with mounting method: surface mounted or flush mounted boxes may require large holes at the rear of the wall outlet for cable entry requiring little or no strain relief, whereas boxes with cable entry visible to the end user will need cable sealing and strain relief. Wall outlets covered in the product specification will include a fibre management system (FMS) for managing the incoming cables or fibres. The FMS may include trays for splicing pigtails to incoming cable/fibre. This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of an optical fibre wall outlet, in order for it to be categorized as an European Standard product. 1.2 Operating environment The tests selected combined with the severity and duration is representative of indoor environments defined by: EN 61753-1 category C Controlled 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 recognized 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 recognized quality assurance programme. 1.5 Allowed fibre and cable types All EN 60793-2-50 fibres can be stored in the Terminal Equipment Box with a minimum storage radius of 20 mm (up to a storage length of maximum 2 m). Smaller storage radii down to 15 mm are possible with the EN 60793-2-50 B6A fibre types, but in this case the reduction in mechanical reliability should be taken into account (see Annex A). If hybrid cable is used then only the fibre portion is considered in this product specification.

IEC 61977:2015 applies to the family of fibre optic filters. These components have all of the following general features: - they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port; - they modify the spectral intensity distribution in order to select some wavelengths and inhibit others; - they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned; - they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; - the ports are optical fibre or optical fibre connectors; - they differ according to their characteristics. They can be divided into the following categories: - short-wave pass (only wavelengths lower than or equal to a specified value are passed); - long-wave pass (only wavelengths greater than or equal to a specified value are passed); - band-pass (only an optical window is allowed); - notch (only an optical window is inhibited). It is also possible to have a combination of the above categories. This standard establishes uniform requirements for the following: optical, mechanical and environmental properties. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonization of a number of terms and definitions with other generic specifications; - deletion of the quality assessment level clause.

IEC 61300-3-35:2015 is available as IEC 61300-3-35:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61300-3-35:2015 describes methods for quantitatively assessing the end face quality of a polished fibre optic connector or of a fibre optic transceiver using a fibre-stub type interface. Sub-surface cracks and fractures are not considered in this standard. In general, the methods described in this standard apply to 125 μ cladding fibres contained within a ferrule and intended for use with sources of ≤ 2 W of input power. However, portions are applicable to non-ferruled connectors and other fibre types. Those portions are identified where appropriate. It is not the intention of this standard that the size of scratches should be measured, the dimensions and requirements are selected such that they can be estimated. There is no need to measure for example if a scratch is 2,3 μm wide. This second edition cancels and replaces the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modification to the title; - addition of some terms and definitions; - reconsideration of the specific values of Tables 1 to 4 to reflect the current market situation; - addition of visual requirements for single-mode transceivers using a fibre-stub interface in Table 3; - addition of a sentence in 4.1 concerning the susceptibility of the methods to system variability.

IEC 62005-9-1:2015 establishes a general reliability qualification program that applies to all passive fibre optic components except connectors and connector assemblies, the passing of which, suggests a minimum level of reliability assurance and allows that specific device to be called qualified to this standard. The objectives of this International Standard are as follows: - to specify the requirements for a general reliability qualification standard (RQS) for passive optical components; - to give direction to the supplier and to the end user on the production and purchase of passive optical components to meet and verify reliability qualification standards for certain specified service environments; - to give the minimum list of reliability qualification stress tests and conditions; - to establish guidance for the selection of appropriate measurements and pass/fail criteria; - to give relevant references; - and to establish the minimum reporting requirements. This standard defines a series of stress tests, their severity, sequences, quantities of devices under the test (DUT), acceptance criteria, and reporting requirements. It also gives guidelines to selecting appropriate measurements and pass/fail criteria. Keywords: reliability qualification standard (RQS) for passive optical components
