What is Fiber rollout?

When we talk about fiber rollout, we're referring to the use of optical fiber to connect to the internet. Unlike traditional copper data transmission, optical fiber data transmission uses a beam of light to send data through optical fiber glass cables, allowing data to travel at the speed of light and inside optical fiber wires as thin as a tenth of a human hair. Fiber broadband is the fastest Internet medium to provide Internet speeds over one gigabit per second.

What are the different ways to Connect to Fiber Rollout

When connecting to optical fiber cables, depending on the connection quality, there are different kinds of fiber connections your Internet Service Provider may use.

These are referred to as "Fiber to X," where X refers to the end of the connection.

  • The FTTP/FTTH/FTTD is the initial set of connections. These are the most direct fiber lines, which are known as "Fiber to the Premises," "Fiber to the Home," or "Fiber to the Desktop." TThese connections are typically the most expensive because they are the purest kind of fiber with no copper wires and are also the fastest.
  • Your ISP may also provide fiber through a “Fiber to the Building” service (FTTB). The fiber connection is terminated at your building, and the link is subsequently disseminated to the occupants through copper wires. Hotels, office buildings, residential buildings, and even schools employ this form of connection.
  • Finally, the most cost-effective connections are FTTC/FTTN/FTTS, or "Fiber to the Cabinet/Curb," "Fiber to the Neighbourhood," or "Fiber to the Street." Fiber finishes at a box on the street and is then distributed via copper cables to buildings and establishments within a 1000-foot radius. Typically, this sort of fiber connection costs the least amount of money.

Once the fiber network has reached your location, you can connect to it through fiber WiFi or a more traditional LAN network. Fiber internet is known for being the fastest and most reliable at home.

What is fiber backhaul?

The connection between a base station or cell tower and the internet is known as backhaul. Fiber Backhaul is a type of connection that is made with fiber. The physical installation of fiber, which can be in the ground, strung on utility poles, or any other way to connect the base station to the internet, is known as fiber backhaul.

What is ADSS? (All-Dielectric Self Supporting)

ADSS cables, or all dielectric self-supporting cables, are a type of cable that is ideal for laying fiber in rural areas or establishing long-distance links between cities. These cables are metal-free and do not have any bonding or grounding issues. Because they can be put in existing power lines, they are cost-effective

ADSS cables are made from Aramid yarn, which offers a high strength-to-weight ratio as well as excellent fabric integrity. Even in the summer, aramid yarn keeps cable sag to a minimum. They can be installed on existing or new aerial support structures for spans of up to 1000 metres.

What is the difference between aerial and underground cable deployment? (pls write benefits of each)

Below are the primary distinctions between aerial and subsurface cable deployment

Aerial Fiber Deployment:

This sort of fiber deployment is ideal for remote and hard-to-reach places where typical underground installation is neither feasible nor cost-effective. Aerial fiber deployment is commonly utilised to provide broadband in mountainous and difficult terrains. It's also good for temporary use or when high-speed fiber broadband needs to be set up quickly. Aerial optical cables come in a variety of designs to suit a variety of uses.

Environmental conditions, such as a storm, have an impact on aerial deployments. Variations in temperature might cause the cable to expand or contract.

Underground Deployment:

The most major advantage of an underground fiber deployment is that the cable is protected from extreme weather conditions. Installing underground fiber, on the other hand, is costly and time-consuming, and it necessitates Right of Way (RoW) clearances from the relevant authorities. Furthermore, if not handled and labelled properly, the underground wire can be dengerous. Other challenges associated with this type of fiber rollout include the expense of essential equipment and the availability of expertise.

What are the types of fiber deployment? (like aerial, underground, undersea etc.)

Aerial deployment and underground deployment are the two main methods for deploying fiber networks.

Fiber broadband cable is typically strung between utility or electricity poles in aerial deployments. Fiber cable, on the other hand, can be buried directly beneath the earth or inserted into a duct dug in the ground as part of an underground deployment. If placed directly in the ground, the cables can also be ploughed in or buried in a trench. This is the most popular method of deploying fiber networks. When compared to aerial deployments, underground fiber deployment is more aesthetically appealing.

A type of underground deployment is subsea deployment. Around the world, there are about 400 submarine cables in use. The optical fiber cable is laid under the water as part of this deployment, allowing massive volumes of data to be delivered at ultra-high speeds. As a result, whether you watch a video or play an online game, it gets turned to light before being sent across the ocean through optical fiber cable. It is then transformed back to video before arriving at its destination. As a result, subsea cables are at the heart of cross-continental internet transactions and communications.

How is Fiber laid?

Fibers are laid using a variety of techniques:

Ducting and Trenching:

Ducting and trenching are the most popular and conventional methods for laying fiber. This entails digging or motorised soil excavation, then putting optical fiber in the trench. Because the fiber is fragile, it must be handled with care. When it comes to fiber deployment, there are a few things to keep in mind, such as avoiding bends in the trenches.

Mini Trenches:

This technique entails digging small trenches and is commonly used to instal fiber in sidewalks and roads. This approach is not recommended for sandy or gravelly soils. This technique is used for faster fiber deployment

Aerial Cables:

The most popular approach is to tie a wire rope messenger to a small gauge wire between poles. The messenger strand component of lashed cable must be correctly tensioned to withstand the required loading conditions. This reduces cable stress while maintaining the needed sag in the messenger and staying within the safe standards limit.

Buried Directly:

In this method, small perforations on the surface are constructed to lay the fibers. Despite the fact that this method is similar to tiny trenches, it does not require ducting. This method of laying fiber is commonly utilised in metropolitan areas where obtaining Right of Way for ducting is difficult.

Horizontal Directional Drilling:

In this methor, a drilling rig is utilised to make a shallow arc following a predetermined path. This technique has the least amount of environmental damage, hence it is preferred when trenching or ducting is not an option.

Is Fiber rollout expensive?

The cost of the fiber roll-out is high and it is vital for service providers to choose the correct fiber roll-out strategy and to balance the expenses of CAPEX and OPEX (operational expenditure). The cost of fiber rollout comprises the cost of equipment, trenching, and fiber. Trenching accounts for the majority of the entire cost of fiber deployment. As a result, aerial fiber deployment, which does not require trenching, is much less expensive than underground distribution.
