Sinis top 3 aeris inflatus micro fibra funis optici supplementi, GL plus quam 17 annorum experientiam habet, Hodie fibram specalem funem opticum SFU introducemus (Fibra lenis Unit ).
Fiber Unitas lenis (SFU) constat ex fasciculo radiorum incurvationis inferioris, G.657.A1 fibris non waterpeak, strato acrylato sicco incluso, et levi et externo polyethylene costato munito, ad applicationem in retis accessu.Installation: spirans in microductos 3.5mm.aut 4.0mm.(intra diametrum).
1. General
1.1 Haec specificatio requisita operit funalium opticorum fibrarum unius modi copiam.
1.2 Unus modus funis optici fibris huius specificationis exigentiis obtemperabit et generaliter occurrit quaevis novissimae ad commendationem G.657A1 pertinentes ITU-T.
