The pulling and braking system employed should operate smoothly to prevent any jerking or bouncing of the cable during placement. The system should be controllable and able to maintain a constant and even tension on the cable during the installation process. Pullers and tensioner should be equipped with tension indicator and limiting devices. Tensioner wheels should be controlled so that a constant back tension is maintained at all pulling speeds. A braking system to maintain proper cable tension when the pulling is stopped is also required. 3.5 Sheave diameters larger than those specified in Paragraph 2.5 are recommended at the payoff reel position and the take-up or winch location. A sheave diameter larger than the minimum required offers the advantage of reducing the load applied to the cable.
Different single mode optical fibers defined by ITU-T include G.652, G.653, G.654, G.655, G.656 and G.657. Each single mode fiber type has its own area of application and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single mode optical fiber through to the present day. Choosing the right one for your project can be vital in terms of performance, cost, reliability and safety.
Understanding Fiber Optic Cable Jacket & Fire Rating
Fiber optic cable is constructed from the inside core, cladding, coating, strengthen member to the outside cable jacket. As the bare fiber is easily broken, fiber optic cable jacket is needed to provide protection for the shielding and conductors within the cable. The cable jacket is the first line of moisture, mechanical, flame and chemical defense for a fiber cable.
The paper evaluates various technologies (wireless, hybrid and all-fibre) available to roll-out high speed first mile networks with speeds of 50 Mbit/s. It becomes clear that though wireless technology will be very important, it will not be the dominant technology to connect homes and businesses to broadband networks. Both in performance as in investment the wired technologies have the advantage. Wireless will be used to bridge the first meter, but not the first mile.
Hybrid copper-fibre networks (also known as Fibre to the Node/Curb) use the existing copper networks (cable, telephone and electric) to bridge the distance from the end-user to the fibre node, which is situated closer to the end-user than traditional exchanges. The speeds available for DSL connections are dependent on the distance between customers and the switch, with speeds deteriorating rapidly with distance so that high bandwidth, for example at 50 Mbit/s has a range limited to 450 meters which in most countries would cover only about a tenth of the population. Thus, in order to come within reach of customers high speed fibre networks are being brought to the curb or node (street cabinets). Cable networks, which are being upgraded in a number of OECD countries, may have an advantage because of having a higher maximum speed than DSL, but this is often outweighed by the shared nature of cable networks which means that the more users using the network at the same time, the less bandwidth is available per user. Although Broadband over Powerline technology is often cited as a potential competing technology to cable and DSL, there has been little large scale implementation to date of this technology and it is therefore hard to assess its potential in the market.
