How to install ADSS optical fiber cable ?
1. The tips of the SRL rods should align at the end. Do not force the rods or use tools to install them. Forcing the rods or using tools may damage the cable jacket.
2. Align the color band on the deadend with the color band on the SRL and wind one leg of the deadend on approximately two feet.
3. Insert the thimble clevis into the loop.
4. Align the color band on the second deadend leg with the color band on the first deadend. Wind the second deadend leg over the SRL for approximately two feet. Continue winding the deadend legs over the SRL until both legs are snapped in place.
5. Connect the thimble clevis to the hardware (or to the extension link and thenthe hardware) mounted on the pole.
6. Tangent hardware is normally installed after the span has been tensioned. Figure 7 below illustrates a front and side view of a Tangent Support. To install the cable, open the hinged top and insert the bottom pad. Place the cable on the pad, then position the top pad over the cable, close the top and tighten the bolt to hold the cable in place.
The upfront cost of such networks is of concern to investors. The Trans Pacific Express network between Asia and the United States cost USD 500 million12 and will deliver a maximum of 5.12 Tbit/s with 1.28 Tbits initially lit. There are therefore two models used to finance these networks. The traditional way in the last decades has used a consortium of (national) incumbent telecommunication companies, as with the Trans Pacific Express network. There is little competition on some of these cables with rights of usage shared by the consortium members. This has led incumbents in some countries to abuse their position and charge high rents on submarine cables. On some undersea crossings competitive cables have been built and in certain cases with new sources of financing through large private equity parties. The submarine cable would first be financed by the private parties and costs recovered by capacity sold to telecommunications carriers as a carrierís carrier. The maximum capacity on a fibre is so high that the route is often overbuilt. In a competitive market with multiple providers providing similar cables, overbuild might result in competitors pricing on marginal costs only, which are close to zero. It is these enormous investments, technological developments, combined with an overbuild of capacity and strong competition, especially on the Atlantic routes, that led to the bankruptcy of several trans-oceanic networks in the recent past13 and strong consolidation following that. Similar economic effects were seen in continental/backhaul networks and offer insight in the economics of fibre networks that are characterised by abundance and low marginal costs for expansion leading to difficulties in highly competitive markets.
This will play a role in the discussion of investment aspects and business models.
The term backhaul networks is used loosely in this paper to refer to all networks that are not last/first mile networks and are not long-haul networks. Other terms for these networks are Metropolitan Area
Networks, Wide Area Networks, Backbones, Regional networks etc. There is a huge variance in these sorts of networks, but they normally only reach up to 100-200 km in densely populated areas. These networks are used to carry traffic from the local and regional switching offices to the long-haul networks, or to distribute the traffic in metropolitan and regional areas between Points of Presence (POPs), ISPs, other
