Fibre organisers and closures to be used in optical fibre communication systems - Product specifications - Part 3-2: Singlemode mechanical fibre splice

1.1 Product definition This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements, which a singlemode mechanical splice shall meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking and identification details are given in 3.5. Although in this document the product is qualified for EN 60793-2-50 types B1.1 and B1.3 singlemode fibres, it may also be suitable for other fibre types. 1.2 Interoperability The installed mechanical splice fits into a fibre management system with optical fibre splice cassettes or splice trays. This European Standard specifies the following two physical interface dimensions: a) cross sectional profile with width, height or diameter (in millimetres); b) length (in millimetres). 1.3 Expected performance In this document, the performance of a mechanical splice is given with identical fibres only. Losses associated with fibre cladding diameter and mode field mismatch are not taken into account. The measured attenuation is a function of the core concentricity, cladding non-circularity and alignment capability. The optical return loss performance is a function of the index matching gel and the fibre end face preparation. 1.4 Operating environment The tests selected combined with the severities and durations are representative of an outdoor enclosed environment defined as category U in EN 61753-1. To ensure that the product can be used in closures, boxes or street cabinet for categories A, G and S (as defined EN 61753-1) the specified lower temperature is extended to - 40 °C and requirements for temporary flooding have been added. 1.5 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. 1.6 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This standard does not cover quality insurance.

Delilniki za optična vlakna in kabelske spojnice za optične komunikacijske sisteme - Specifikacije izdelka - 3-2. del: Enorodna mehanska optična spojnica

1.1 Opredelitev izdelka
Ta standard vsebuje začetne zahteve za dimenzije, optične in mehanske zahteve ter zahteve za okoljsko učinkovitost, ki jim mora ustrezati enorodna mehanska spojnica, da bi bila opredeljena kot izdelek standarda EN.
Ker so dovoljene različice in različne stopnje zmogljivosti, so podrobnosti o označevanju in identifikaciji izdelka navedene v 3.5.
Čeprav je v tem dokumentu izdelek kvalificiran za vrste B1.1 in B1.3 enorodnih vlaken po EN 60793-2-50, je lahko primeren tudi za druge vrste vlaken.
1.2 Medobratovalnost
Nameščena mehanska spojnica se prilega v sistem upravljanja vlaken s kasetami ali pladnji za optične spojnice. Ta evropski standard določa mere naslednjih dveh fizičnih vmesnikov:
a) prečni profil s širino, višino ali premerom (v milimetrih);
b) dolžina (v milimetrih).
1.3 Predvideno delovanje
V tem dokumentu je delovanje mehanske spojnice podano le z identičnimi vlakni. Izgube, povezane s premerom plašča vlakna in neskladjem rodovnega polja, niso upoštevane. Izmerjeno slabljenje je funkcija koncentričnosti sredice, nekrožnosti plašča in zmožnosti poravnave.
Optična povratna izguba je funkcija gela za indeksno združljivost in priprave zaključne strani vlakna.
1.4 Delovno okolje
Izbrani preskusi v kombinaciji s strogostjo in trajanjem predstavljajo zaprto okolje na prostem, opredeljeno kot kategorija U v EN 61753-1. Da bi zagotovili, da se izdelek lahko uporablja v ohišjih, škatlah ali uličnih omaricah za kategorije A, G in S (kot jih opredeljuje EN 61753-1), se je opredelitev za spodnjo temperaturo razširila do -40 °C in dodane so zahteve za začasno poplavo.
1.5 Zanesljivost
Medtem ko je pričakovana življenjska doba izdelka v tem okolju 20 let, skladnost s to specifikacijo ne jamči zanesljivosti izdelka. Ta se mora predvideti z uporabo priznanega programa za ocenjevanje zanesljivosti.
1.6 Zagotavljanje kakovosti
Skladnost s to specifikacijo ne jamči skladnosti izdelave izdelka. Ta standard ne zajema zagotavljanja kakovosti.
