What is pushable fiber and why do we need it?

Posted by Joe Byrne

When it comes to deploying fiber networks, installers and planners face multiple challenges. This is particularly true when it comes to the last drop section, between the curb and the premises, or inside buildings themselves. The natural landscape and the built environment vary between deployments, which makes every install a standalone civil engineering project that requires planning, skill and experience to deliver.

Time is money, so deployments need to be carried out as quickly as possible – without compromising quality, reliability or upsetting home or business owners.

Traditional methods of installing fiber (blowing or pulling) are not well suited to the demands of the last drop. This has led to the emergence of pushable fiber – a relatively new way of meeting deployment challenges.

This blog looks at what pushable fiber is, its advantages and why it is needed.

Why we all need fiber broadband

Posted by Paul Ekpenyong

Many years ago when I was in Japan on business, I had the pleasure of travelling on the Tōkaidō Shinkansen bullet train between Tokyo and Osaka. It is now the world's busiest high-speed rail line, with up to thirteen trains with sixteen cars each (containing 1,323 seats), running every hour in each direction between Tokyo and Osaka - with a minimum gap of three minutes between trains.

My journey was in the days when we were still talking about the possibility of high speed trains and the Channel Tunnel in the UK. Having ever only travelled on Amtrak and UK InterCity trains, the journey on the bullet train was a complete revelation. It was comfortable, fast, (really fast!) and smooth, as it transported us between the two cities. In fact, it was so effortless (compared to the rattling of the US and UK trains), that you hardly felt you were moving as it sped along. I marveled at the technology that made that possible and wondered why we were so far behind in other countries.

Delivering in-building fiber - without disruption

Posted by Rich Contreras

Whether through streaming HD content from the internet or accessing "traditional"’ TV programmes online, consumers are widening the ways in which they watch films and TV shows.

Fiber provides the perfect network to transport even the most bandwidth-intensive content into subscribers' living rooms, providing the ability for it to be watched on TVs, tablets, phones or computers.

Consumers understand this, which is why fiber networks are becoming more and more popular around the world.

Real estate companies are increasingly reflecting this demand by ensuring that their apartment buildings and condominiums can support the latest technology through fiber networks.

Installing a state of the art in-building fiber network helps attract and retain tenants and can differentiate against similar properties in the area.

Building a national fiber backbone in Africa

Posted by Tim Gigg

Many of us have experience of deploying fiber in the US and Europe, and know how tough that can be. However, installing fiber in Africa has its own unique challenges, as I found out when I worked at Ghana Telecom for two years after it was acquired by Vodafone.

Having never worked in Sub-Saharan Africa, I thought it would be a great challenge and opportunity, and was delighted when I got the job. Arriving was an experience in itself.

For those who have never been to Sub-Saharan Africa, it is difficult to convey the impact of arriving and stepping off the plane into 36 degrees Celsius; taking in your first impressions while your senses are assaulted by the noise, heat, and environment.

You are either hooked or can’t wait for the return flight. Fortunately, I was in the first camp.

Why GPON needs to change - introducing NGPON2

Posted by Dave Stockton

When deciding the best fiber architecture for their network, planners have to make the choice between point to point (P2P) or a passive optical network (PON).

Both have strengths and weaknesses, as we covered in a previous blog

The majority of network operators have invested in GPON and GEPON architectures.

However, since they’ve been installed, predicted bandwidth needs have increased dramatically, meaning that they now need to change.

Consequently, much work has been done in creating a successor to GPON and GEPON, ensuring that PON architectures are able to underpin future, higher capacity networks.

After a false start along the way, the new NGPON2 standard, created by the FSAN group, looks set to achieve this.

Installing fiber and preserving history at Denver University

Posted by Dan Patuto

One of the toughest implementations to manage successfully can be when installing fiber at a Brownfield site, as we recently found at Denver University in Colorado.

Often crews won’t know what is already in place, making it difficult to plan, and forcing installers to think on their feet and reroute cables to fit into the available space.

The difficulty is compounded when buildings have been constructed before the 1930s - a time when building codes were more relaxed (or non-existent). Wherever they are located in the US, most of these don’t have integral ducts, and no-one currently employed has any knowledge of the structural details of how they were built. Spaces are normally cramped, leading to fiber being routed through multiple 90 degree bends to reach its destination. 

Adding to the potential headache, many buildings will have already been retrofitted with telephone or power cables after they were built, and the plans may not be available. Finally, particularly for older buildings, the aesthetics cannot be disturbed, so the installation has to respect the existing fabric, which may be structurally fragile by now.

Picking the right fiber connector – PC, UPC or APC

Posted by Shaun Trezise

I wrote a blog post last year on the different types of connectors available, which sparked a great deal of  feedback and discussion, demonstrating how important the whole topic is to both fiber installers and network planners alike.

Thanks again to everyone around the world that contributed, both directly on the PPC's blog and through various social groups.

To recap, I covered SC, LC, FC, ST and MTP/MPO connectors, and looking through the comments I thought it would be beneficial to focus on one area that the original post deliberately didn’t cover - the differences between Angled Physical Contact (APC) and Ultra Physical Contact (UPC) connectors.

Beside one having a green body and the other being colored blue, the different ways they both treat light is crucial in planning a network, as several readers pointed out.

To help us understand all this jargon, let’s look back at why the original Flat Fiber Connector evolved into the Physical Contact (PC) connector and then onto UPC and APC.

Harnessing military skills for fiber cable roll outs

Posted by Tim Gigg

As Britain and the United States cut back on defence spending, the British Army will reduce the size of its trained-strength force from 101,210 in 2012 to 82,000 regular personnel by 2018. Additionally, the Royal Air Force and Royal Navy are each losing about 5,000 staff. Meanwhile, the US Army is shrinking from 520,000 to 450,000 with the USAAF and US Navy also shedding jobs.

To put this in perspective, when I left the British Army in 1998, we had double that number. Now we don’t have enough soldiers to fill our national football stadium at Wembley – there would still be 8,000 seats free for the opposition.

Is the plan for Irish fiber broadband about to get stuck in a ditch?

Posted by Paul Ryan

The Irish government has announced an ambitious National Broadband Plan (NBP) to intervene in the provision of broadband services covering 700,000 homes and businesses in rural areas. At best, the locations identified by the Government today have only very basic, if any, broadband services and commercial networks have no plans to provide them with high speed broadband.

Whilst the scheme is not specifically targeting fiber broadband, by implication most observers believe that the tender requirements dictate a fiber solution. The NBP aims to definitively address Ireland’s connectivity challenge by removing existing cost barriers, preventing commercial operators from providing high speed services to end users across the entire country.

Picking the best fiber installation partner: why it starts with an RFP

Posted by Tom Carpenter

When creating a fiber network, even the best laid plans can be upset by deployment issues. While some of these, such as unexpected weather or unforeseen environmental problems can’t be legislated against, many factors can be controlled through good planning, and in particular by providing a clear, well-structured Request for Proposal (RFP).

Consequently, in this article I want to outline the four key steps to writing and issuing a successful RFP,  vital in helping you choose the best fiber installation partner for your project. Get it right and both the network planner and the installer have a strong platform to work to, which makes it easier to cope with any unforeseen problems if they occur.
