Abstract: This paper discusses two redundancy plans of distributed base stations and digital optical-fiber repeater stations for the long tunnels of Jining-Tongliao Railway. The single-network interleaving redundancy plan for distributed base stations is recommended after analyzing and comparing single-network interleaving and double networks for the same site respectively for both redundancy plans.

Key words: long tunnels, distributed base stations, digital optical-fiber repeater stations, single-network interleaving, double networks for the same site
