Delivering fiber successfully to MDUs and office blocks

Posted by Dave Daly

The advantages of fiber optic cable over copper wire are well understood. Fiber can transfer more data, in less time, over longer distances than copper. It does not degrade like copper, requires little maintenance and loses only a fraction of its signal strength over 100 meters.

Today, there is a growing demand for fiber, as consumers expect faster Internet speeds. This demand is largely being fuelled by video and music streaming services and over the top (OTT) bundles. Additionally, businesses also require faster broadband, to grow and scale their organisations in a digital and global world.

In this post, we will explore how fiber is successfully delivered to multi-dwelling units (MDUs) and commercial buildings.

Pioneering the 4th Utility – Fiber to the Home

Posted by Dave Daly

In this post, we explore how you can future proof and differentiate a property through delivering a fiber solution, while also increasing customer satisfaction.

The Challenge of Delivering Fiber to Multiple Dwelling Units

Over half of the world's population lives in units of 100+. In cities this figure can be even higher. This concentration and variety creates a challenge for operators looking to install fiber to the home (FTTH) connections. Essentially, multiple dwelling units (MDUs) are like snowflakes - no two are the same, meaning that each one has to be handled as a separate, complex civil engineering project.

Adding to this complexity, the vast majority of these buildings were constructed before fiber networks were even thought of, meaning they aren't designed to accommodate standard fiber connections. 83% of US MDUs were built before 2000, and over half (52%) before 1980. So there is often no obvious way to route fiber to individual apartments.

Installing In-Building Fiber Broadband: First Stage and Connectors

Posted by Dave Daly

These days, operators are faced with an increasing requirement to deploy in-building fiber broadband networks. The rising demand from consumers for superfast broadband services, coupled with the growing urbanization of the marketplace, means that many operators need to focus on installation efficiencies and effectiveness.

Bringing fiber into the building

The first installation step is to get fiber cable into a multi-dwelling premise. It has to be routed from the point of presence (the outside distribution box in the example diagram below) into the building through the wall and plugged into a further distribution box or distribution frame in the basement or a comms room.

The challenge of delivering fiber to multiple dwelling units

Over half of the world’s population lives in units of 100+. In cities this figure can be even higher. This concentration and variety creates a challenge for operators looking to install fiber to the home (FTTH) connections. Essentially, mutliple dwelling units (MDUs) are like snowflakes - no two are the same, meaning that each one has to be handled as a separate, complex civil engineering project.

Adding to this complexity, the vast majority of these buildings were constructed before fiber networks were even thought of, meaning they aren’t designed to accommodate standard fiber connections. 83% of US MDUs were built before 2000, and over half (52%) before 1980. So there is often no obvious way to route fiber to individual apartments.

Building owners and their tenants want the speed of fiber, but are less keen on any disruption or damage it might bring. 30% of consumers that sign up for FTTH service change their minds when an installation technician asks if he can drill holes in the wall and run cables along it.

So how can operators make their deployments cost-effective and keep consumers and building owners happy? There are five key rules to follow:

Understanding optical loss in fiber networks - and how to tackle it

Posted by Shaun Trezise

Optical fiber is a fantastic medium for propagating light signals, and it rarely needs amplification in contrast to copper cables. High-quality single mode fiber will often exhibit attenuation (loss of power) as low as 0.1dB per kilometer.

Power or strength of the signal (measured in dB), will always be higher at the head end or central office of the network connection than at the customer end, as it’s impossible not to incur some degradation of light over the length of the network connection. If the impact is too great then performance suffers, so understanding and measuring these losses is a critical part of network installation and testing.

For network planners, the bulk of the loss budget is spent between the final node and the customer’s network terminal. Splitters add significant loss to this part of the network - far greater than fiber connectors and other passive components. When measuring the attenuation effects of these components, we use the terms insertion loss (IL) and return loss (RL).

Meeting the multi dwelling unit fiber challenge

Posted by Simon Roberts


The combination of greater urbanization and pressure on space means that more and more of the global population is now living in multi dwelling units (MDUs), such as apartment blocks. This adds another level of complexity for operators looking to deploy fiber to the home (FTTH)/fiber to the premises (FTTP) networks. Not only do they have to cost-effectively connect the building itself, but they also need to deliver fiber to paying customers within the building, in a timely and efficient manner. MDUs also come in all shapes and sizes, from multi-story apartment blocks with hundreds of tenants, to low rise buildings with much smaller numbers of occupants.

This was the challenge that faced Liquid Telecom when it came to deploying fiber to Kenyan capital Nairobi. Liquid Telecom is building Africa’s largest single fiber network, currently stretching over 18,000km across Uganda, Kenya, Rwanda, Zambia, Zimbabwe, Botswana, DRC, Lesotho, and into South Africa. It delivers the highest quality FTTH services, with customers benefiting from speeds in excess of 100Mbps.

4 questions to ask when installing fiber in multiple dwelling units

Posted by Rich Contreras


As the pace of fiber to the premises (FTTP) deployments increases, operators face a different challenge – successfully installing fiber within multiple dwelling units (MDUs), such as apartment buildings, offices, and hotels.

What makes this task difficult is that MDU is a whole new concept for many operators – particularly when installing fiber in existing buildings, with congested ducts. Most older buildings didn’t plan for future upgrades to technology such as fiber, limiting the space even more in these scenarios.

Every implementation is different, so to help planners and crews, here are four questions you should ask before beginning the process:

8 questions to ask before installing fiber in your building

Posted by Rich Contreras


Across the world, people are increasingly demanding faster broadband - and it is often one of the factors they take into account when choosing where to live. As well as attracting tenants, being able to offer fiber broadband has other benefits for building owners and operators.

A study by the FTTH Council Americas found that access to fiber boosted real estate prices by an average of 3.1 per cent across the United States. These findings build on research that communities with gigabit broadband have a higher per capita GDP.

Consequently, landlords are looking at how they can fiber up their buildings, to attract and retain tenants. But for many this is a new area, so what are the pitfalls they need to avoid and the questions they should ask of any contractor? Based on my experience, here are the eight areas to focus on if you want your project to be successful:

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.

Fiber deployments and the Internet of Things

Posted by Joe Byrne

Previously, we’ve looked at the applications that will drive the need for Fiber to the Home (FTTH) networks. One of the areas mentioned was the Internet of Things (IoT), and in this blog I’d like to look in more detail at what it is and what it will do.

What is the Internet of Things?

In a nutshell the Internet of Things involves providing previously ‘dumb’ devices with connections to the internet. A good definition is from BT - “The Internet of Things refers to technologies that allow networked devices to sense other devices and interact and communicate with them.”

The ‘Things’ are real world objects – essentially anything that can have a sensor embedded within it and is able to communicate wirelessly with the wider world, such as vehicles, machines, buildings, people, animals, goods or the environment around us. One Dutch farmer has fitted his cows with sensors, so he can be alerted to any health issues or when they need milking.
