Key factors when choosing between buried and aerial fiber deployments

Posted by Joe Byrne


Careful planning is crucial if a Fiber to the Premises (FTTP) installation is to be a success. It begins with choosing your architecture and in a previous blog we looked at the advantages and disadvantages of PON and P2P architectures. This was part of the Complete Guide to Fiber to the Premises eBook, a free download that covers the factors you need to take into account when making choices for your implementation.

After choosing an architecture, the next challenge is cost-effectively deploying last drop connections. The first factors to take into account revolve around the terrain and environment, which affect whether to go for a buried or aerial deployment. Let’s look at these in more detail:

Fiber to the campus - overcoming fiber optic installation challenges

Posted by Shaun Trezise

Modern higher education is increasingly underpinned by technology. Whatever the subject, teaching, research and administration all rely on the fast transmission of data to students, professors and staff.

And with intense competition for the best students and researchers, a slow network can mean the brightest minds go elsewhere.

High speed fiber networks are therefore crucial parts of the infrastructure of university and college campuses across the world.

The challenges of campus networking

Rolling out a fiber network across a university campus is complex and potentially costly for four key reasons:

Fiber protection – in the toughest of conditions

Posted by Tom Carpenter

In business, everyone expects high quality products and services, meaning that praise from customers is pretty rare. So, when our US partner Core Telecom forwarded me this email from Rich Jones of Metasoft Inc. I have to say it made my day.

Normally in our blogs, we focus on sharing our knowledge and expertise with the industry, rather than talking about ourselves or our products. However, I felt compelled to share this email, so I hope you forgive me this one exception:

Hello Rene,

All is well. Much has happened with regards to the Tuff Duct and Miniflex fiber at the site where it was installed.

Choosing fiber cable protection to meet fire regulations

Posted by Shaun Trezise

Fire regulations for fiber cable protection vary across the world, meaning that a cable suitable for use indoors in one country may very well not be allowed in the same building structure elsewhere in the world. With these differences it’s not surprising if there’s confusion out in the field.

Here’s a brief guide to navigating around the potential minefield of meeting fire regulations in the United States and Europe, particularly in two areas - transitioning fiber from outdoor to in-building and halogen content of cables.

Fiber to the Premises Deployment - comparing PON and P2P architectures

Posted by Shaun Trezise

The socio-economic benefits of fiber are beyond question. Fiber to the Premise (FTTP) can boost economic development, spark innovation and improve the way people live and work.

For network operators looking to deploy FTTP there are multiple factors that need to be taken into account when planning an installation. These include:

  • Topography
  • Regulation
  • Technical choices
  • Implementation cost
  • The need to future-proof investment

Every deployment is different. Therefore to help network operators make the right choices for their implementation we’ve created the Complete Guide to Fiber to the Premises Deployment eBook. Which is available as a free download here. Over the next few months we’ll summarise some of the key points of the guide in a series of blog posts, beginning with fiber architectures.

Cheapest isn't always best when it comes to fiber cable

Posted by Simon Roberts

Recently I visited Thailand on business, providing me with a vivid reminder of my back packing days twenty years ago. Then my adventure was raw, fresh and exciting and I was greeted in Bangkok with eager street vendors trying to sell me cheaper counterfeit goods using the slogan “Same, same but different.” Essentially the quality of these products backs up the traditional English phrase that “you get what you pay for.” 

Over the years both of these sayings have stuck with me. However the combination of human nature and a desire to balance budgets, mean I continue to strive for a bargain.

Fiber Protection Withstands the Big Truck Test

Posted by Shaun Trezise

Fiber has to survive and operate in the toughest conditions. Whether it is during installation or ongoing operation it is vital it continues to function reliably when dropped, hit with a hammer, crushed or generally maltreated.

We’ve carried out extensive crush resistance and impact testing of our fiber, and calculated that our Miniflex cable and protective duct can withstand a force of 4000 Newtons over 100 mm without any damage to the fiber itself. And because of its advanced polymer engineering it springs back and regains its shape over a relatively quick time, ensuring the fiber inside is not pinched or squashed.

Coping with cable congestion - with pushable fiber and PPC Microduct

Posted by Larry Malone

Cost-effectively rolling out new cellular infrastructure is critical for carriers looking to compete in increasingly demanding markets. Technologies such as 4G are crucial to providing the robust, high bandwidth data networks that subscribers want, but deploying them, particularly in complex urban areas, can be difficult. Existing infrastructure, such as around cellular towers, has been built up over years and cannot be removed or replaced. This can make it hard to add new equipment, leading to a headache for both network planners and installers.

Planning a 4G cell tower rollout

To solve this problem a tier 1 US cellular operator used the unique strengths of PPC’s Miniflex microduct and fiber cable to connect a key cell tower to 4G and its existing backhaul network.

Located on the roof of a ten floor hotel, in a busy urban area, the existing internal riser was full of cable, meaning the telco’s options were limited – it could install a whole new riser system (too expensive) or expose the new fiber on the side of the building (likely to be vetoed by the hotel owners).

Speeding FTTP deployments with Dura-Line and Miniflex Pushable Fiber

Posted by Larry Malone
With its products used in thousands of fiber deployments across the globe, Dura-Line is one of the world’s leading suppliers of conduit duct. Installers know and rely on Dura-Line when it comes to ease of deployment, effectiveness and reliability.

Given its market leading position, we wanted to test how the combination of PPC's patented Miniflex fiber cable and Dura-Line’s duct performed together. To do this we worked with Dura-Line and a major local telephone company in the US on out a joint Fiber to the Premises (FTTP) installation to a strip mall in Louisiana. The aim was to measure the compatibility of the two products and to see if the combination improved deployment performance for the installation crew.

Solving the FTTH rollout problem in multiple dwelling units

Posted by Shaun Trezise

Recently PPC was asked to investigate solutions to the problem of a FTTH rollout with no space for microduct. The customer faced the challenge of deploying fiber to 10 high-rise apartment blocks, each containing 180 dwellings, within 2 years. Sounds easy, but factor into the equation that there is no option to add infrastructure and the fiber must be installed through the pre-existing, pre-populated PVC conduits hidden in the voids and screeds. Also add in that no machinery or cable blowing equipment is allowed on site. Then you really have a problem.

Unfortunately for network designers and installation engineers across the world, this scenario is all too common. A lack of foresight when future proofing network infrastructure has resulted in a critical need for fiber cable that can be retrofitted into existing conduit and ducting, often when this conduit is already populated with cables.
