Performance requirements for passive optical nodes: Sealed closures for outdoor environments
This Recommendation refers to passive optical nodes in outdoor environments. It deals with the design of the closure housing as well as the fibre organizer taking into account mechanical and environmental characteristics as well as the characteristics of the optical fibre organizer.The following elements are added for this revision:- a test plan for the performance evaluation of sealed optical closures in 2 basic environments: underground (OS) or above ground (OA);- the simulation of the effect of interventions related to network maintenance.Appendices were added:- a checklist for a systematic product characterization according to L.51;- a list of additional requirements to reflect special environments (e.g., tunnels) or local conditions.
