Think You're Ready for the FTTx Drop Installation?

Posted by Dave Daly

Take our quiz to find out.

When it comes to actually implementing an FTTx network, there are many details to pay attention to.

Choices have to be made based on landscape topography – there is a big difference between an FTTx drop installation in rural and urban landscapes. Regulatory issues need to be addressed. Technical factors must also be carefully weighed – techniques like cable blowing and pulling only work in certain situations.

It is also critical that customers are not inconvenienced at any point during an FTTx implementation. No customer wants their property to be at the center of a major civil engineering project..

Then there is the matter of cost.

Lastly, it's important to consider whether the solution needs to be future-proof. Some cable can be ripped and replaced. But there are other options, such as direct unducted cable, which, once installed, cannot easily be removed or replaced.

These are just some of the many decisions that have to be made before beginning an FTTx implementation.

Do you think you are ready? Take the quiz below to find out.

Hardline Connectors - Hidden Damage Stalking your Broadband Network?

Posted by Eric Purdy

Having the right hardline connectors is often overlooked when doing node replacements, node splits, or tap replacements in a broadband HFC (hybrid fiber coax) network. Because these connectors are not the most expensive part of a project, there can be a tendency to underestimate the amount of trouble they can cause if they are not properly installed or maintained.

In most HFC architectures today, the nodes are getting closer and closer to the subscriber as fiber slowly replaces coax. As the number of subscribers per node decreases, the number of nodes in a broadband network increases.

During these node splits, you will sometimes have the opportunity to improve existing performance by replacing old connectors with new ones. Each connector in a network may cause a small amount of return and insertion loss in the signal performance. If you haven't accounted for this loss in your network design, you will end up not meeting performance requirements, having poor subscriber experience, and not knowing exactly how to determine what went wrong.

Coaxial headend broadband connectivity – improving the performance

Posted by Dave Daly

The broadband headend environment evolves with the advance of technology and expands to satisfy consumer demand for data service. This poses challenges in many ways – space is at a premium, reliable power is essential, security has to be perfect, and the air has to be kept to specific parameters.

With respect to space, the headend environment has seen a transition from standard RG6 cable to high-quality mini-coaxial cable and connectors that have a smaller footprint, such as MCX-type connector products. So to accommodate technologies from video programming to 2-way digital service - the processing, receiving, and transmitting has to be better as the threshold of services such as DOCSIS 3.1 demands a more stringent network performance.

Building Residential Fiber Networks Faster at a Lower Cost

Posted by Dave Daly

The broadband FTTH market is in its infancy in North America and very little attention has been paid to the last 150’ drop necessary to bring a low fiber count connection into customers’ homes. Currently a broadband operator’s fast ROI lies in business and multi-dwelling unit (MDU) applications. To date, the ROI model for single family units (SFU) doesn’t measure up.

How to Harden Closed Loop HFC Systems for the LTE Band

Posted by Rick Haube

LTE networks operating in the 700 MHz band are becoming widespread across North America and are growing globally as well. Broadband cable and some satellite systems occupy some of the same frequency bands.There have also been frequency auctions in the 600 MHz band - so the allocation of shared frequencies will soon span from 600 MHz – 800 MHz.  

Ideally, none of this should be an issue since the CATV coaxial plant is a closed loop transmission medium - if well-shielded coax is used and connections are tight. But often they are not.

It has been shown that  LTE operators do not deliver services well when coaxial networks "broadcast" signals in the LTE band and, conversely, coaxial networks don't deliver services well when they have LTE ingress, commonly caused by loose connectors and poor shielding performance of coax and passive devices.

Minimizing install time with micro trenching

Posted by Martin Gossling

Digging up roads and pavement to install new networks of any sort is never popular. Local residents dislike the disruption and the noise while municipalities have to deal with increased congestion on busy roads, particularly if works overrun.

Installers, therefore, aim to get the job done as quickly as possible to minimize disruption and costs.

However, there's a growing need to install new broadband networks, particularly in congested urban areas, extending them all the way to individual buildings themselves.

FTTP Drop Installations: Fusion Splicing Versus Pre-terminated Costs

Posted by Shaun Trezise

The relative costs involved in connecting subscribers to fiber networks can be deceptive. The critical element when evaluating fiber connections to make in the drops to the premises or even inside homes in an FTTX installation is not materials, but time.

Fiber splicing technicians have specialized training that makes them expensive when compared to someone simply plugging things in. 80% of costs for an FTTP deployment go to labor.

As it turns out, fusion splicing makes a lot of sense for trunk fibers and locations where there are anywhere from 48 to 192 fibers to splice. In the drop locations, where there may be only one or two splices at each location, the setup time for each location may negate any cost savings from fusion splicing.

Choosing the Best Fiber Cable(s) for Fiber-to-the-CPE Installations

Posted by Rick Haube

When it comes to choosing the amount and type of fiber to use in your system, protecting the fiber that carries telecommunications services is of primary importance. Between access fiber to the home (FTTH), and premise fiber to the CPE, there can be uncertainty about when to use which types of fiber cable. Today's most common options include:

  • 900µ fiber
  • 900µ jacketed fiber
  • 250µ fiber within a strong polymer (2-4mm)
  • Fiber cable within microduct

Bringing fiber into a home requires that you carefully consider several factors to choose the correct cable. At all points in the FTTH installation, the fiber must be flexible, tough, and lightweight, and for residences, aesthetically pleasing. Most fiber cables can accommodate one or two of these features but not all four. In addition, you must factor cost into the equation as prices vary - however, the installation and operational cost far outweigh the capital. The bottom line is that each FTTH installation is somewhat unique – whether the site is a multiple dwelling unit or a single residence, there are many variables that will determine which types of fiber are most appropriate in the different parts of the installation. In most cases, one size will not fit all.

Direct bury microduct for fiber: the do's and the don'ts

Posted by Shaun Trezise

The disruption often caused when installing new fiber is never popular. Local residents dislike their roads and sidewalks being dug up while local governments have to deal with increased congestion, particularly if projects overrun their anticipated schedules.

There are big advantages to installing microduct underground since it can be laid relatively quickly and does not require specialist fiber crews.

The cost compared to installing larger sub ducts or direct bury (DB) fiber is lower both in terms of material and time. Direct bury products are generally of heavier construction with thicker sheaths and so are able to withstand higher impact and crush loads. Depending on their make-up, they can be used in excavated trenches, mole-plowed routes or inserted into slot cuts in the surface of roadways.

Here are some tips to make the direct bury microduct for fiber installation smoother, quicker, and more satisfactory for all involved.

Optical connections in the drop network - how to save money and time

Posted by William Crawford


Fusion splicing is often used and is appropriate for trunk portions of a network; it offers low optical and reflection loss and splicing efficiency for large fiber bundles.

When it comes to the drop network, however, with only a couple of connectors per drop, you can achieve substantial cost savings by using mechanical connections or pre-terminated fiber cables. Using fusion splicing in the drop adds time and cost.

In this post, we will examine the impracticality of fusion splicing in the last few hundred feet to the premise vs. cost savings from mechanical optical connections, and pre-terminated fibers. 

Optical loss

The typical loss budgeted for a fusion splice is 0.1dB and 0.3dB for a mechanical connector. Considering that most subscriber drops will have two localized optical connections between their devices and the distribution network, using connections that install fast and with ease should be considered. It is highly unlikely that the optical loss budget in the network design will be affected by these last two connectors - because the loss in each drop is not aggregated in the distribution network, there will be negligible impact on the loss.
