ADSS is an alternative to OPGW and OPAC with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 metres to be installed between support towers. ADSS cable is designed to be lightweight and small in diameter to reduce the load on tower structures due to cable weight, wind, and ice.
In the design of the cable, the internal glass optical fibers are supported with no strain, to maintain low optical loss throughout the life of the cable. The cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light.
Accessories and installation
Fittings used with ADSS cable may be tension type, used at dead-ends where the cable terminates or changes direction, or may be suspension type, only holding the weight of a span with tension transmitted through the next span of cable. Reinforcing rods are used on either side of a support and at dead-ends. Wind-induced aeolian vibration is a factor since ADSS cables have light weight, relatively high tension, and little self-damping. Anti-vibration dampers are installed on each span near the support points. Accessories must not be clamped directly to the cable but instead over reinforcing rods, to protect the cable from electrical and mechanical damage. Termination boxes are used to enclose and protect splices between the ADSS cable and "inside plant" cable runs.
The role of the government in the stimulation of the roll-out of these networks can be in three ways.
The role of a stimulator is defined here as removing the barriers that may impede the investment and roll out in new networks. The role of producer is defined as actually investing in new networks and the role of regulator is limited to the governmentís role as a telecommunications regulator trying to guarantee a competitive marketplace. Whether or not the government will have to perform any of these roles is dependent upon the local situation. A well-defined policy, which is discussed with industry and other stakeholders, with clearly stated goals and timelines, can help identify where bottlenecks are and which areas may be unprofitable. On the basis of such a policy the government can base its decisions to stimulate or to intervene.
Governments, especially municipal governments, can play an important role in facilitating the roll-out of fibre infrastructure. This role can be in providing or facilitating rights of way, and if necessary in joint public-private partnerships in infrastructure development.
The aim of this paper is to provide an overview of developments in optical fibre communication technology and investment. It will provide a broad overview of the facets that are involved with the roll out of networks based on this technology. The paper does not aim to make normative statements on what kind of network is better or should be chosen by OECD countries. It will give an overview of the considerations that are involved in the development of investment in networks, aimed at facilitating more informed choice on such investments, and regulation of future networks.
