How to improve the inspection results of your fiber connectors

Posted by Simon Thompson

Dirt, dust and other contaminants are the enemies of high-speed data transmission over optical fiber, as even the most minor of scratches or defects can present problems further down the line.

Optical fiber connectors are used to join optical fibers wherever a connect/disconnect ability is required.

Connectors are most commonly comprised of a spring-loaded ceramic ferrule, which aligns two mating connectors in a circuit. However, before they can be used in FTTx applications, the connector ferrules first need to be polished to achieve the required angle and end-face geometry.

Applying the right polishing process, or ‘recipe,’ ensures the connector end-faces are free of defects or scratches. While this process is generally managed within a manufacturing facility, there are occasions where assembly and polishing operations need to be undertaken in the field.

In this blog post we explore how connector cleanliness, and the appropriate inspection environment, can impact on your microscope and interferometry readings and suggest the key steps to overcome poor measurement results.

Pre-terminated fiber cable - a great FTTH installation solution

Posted by Tom Carpenter

 When installing fiber at an MDU (multi-dwelling unit), technicians have a few choices for the type of cable they choose. The most important choice is whether to use field-terminated or pre-terminated cable. Both have their strengths and weaknesses, but we find pre-terminated cable is almost always the best choice. In this blog, we’ll discuss the pros and cons for pre-terminated versus field-terminated cable when it comes to cost, installation skills and excess materials.

Is your drop network too old for today’s demands?

Posted by Noah Montena

The quality of components used in drop networks and the skillfulness of the drop installation play a major part in a subscriber’s network performance. But what happens when those parts are out of date?

The parts visible from the headend to the side of the home, and components from the wall plate to the CPE (customer premise equipment), may be brand new and installed properly, but that doesn’t mean most of the premise wiring is up to date.

A mid-year roundup of the 2017 global FTTH broadband market

Posted by Krista Tysco

In today’s technological world, internet speed is important to everyone. Almost every household has multiple web-enabled devices, and with the Internet of Things (IoT) driving increased home automation, it’s not just laptops and mobile devices in the home that will rely on the internet, but everything - lights, appliances, windows, blinds, you name it. Access to high-speed internet is now a top priority for people when moving home or relocating to a new area.

Comparing 3 in-building fiber cable installation methods

Posted by Krista Tysco

A crucial step that every installer will negotiate during fiber cable installation in an apartment block or multi-story office building is to decide on the most appropriate way of getting the fiber cable from the basement of the building to each floor.

In new-build apartment blocks and commercial buildings, this process can often be fairly straightforward - and especially so if the architect has designed the building with fiber in mind and has included a microduct from the basement to each of the floors.

For the network operator the key step is deciding on the best method of getting the cable to each floor - whether that’s by blowing, pushing or pulling the fiber cable. Here we explore the pros and cons of each approach.

What is coaxial cable and how is it used?

Posted by Dave Daly

Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers.It has also been used extensively within homes.

It has been around for a long time as a technology (since the early 20th century) and has many singular advantages for reliable, accurate transmission.

It also has limitations that will cause it to be replaced in some cases by fiber optic cable, category cable or, sometimes, by wireless signals.

The key to the coaxial cable's success has been its shielded design, which allows the cable's copper core to transmit data quickly, without succumbing to interference or damage from environment factors.

The three most common cable sizes are RG-6, RG-11 and RG-59:

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.

Simplicity of Installation is the Key to Product Selection for FTTH

Posted by Dave Daly

If you are trying to decide on a product to include in your network design or installation and you have a choice between several products that meet your technical specifications  is price the only factor that will help you to make your decision?

While it can be tempting to prioritize price, it's also important to think ahead and look to your business' future. Therefore, an important factor to consider during your product selection for FTTH is the simplicity of your installation.

Simplicity

When it comes to fiber installation, it is commonly understood that you need specialized expertise (installing, splicing), and specialized equipment (splicers, blowers, trenching, etc.). The cost of these things is well known and considered to be part of doing business, and is often the decisive factor in how or if an FTTH installation goes forward.

How Terminating Unused Ports Improves Broadband Network Performance

Posted by Dave Daly

Terminators are simple devices that electrically terminate RF coaxial ports, both inside and outside of the home. The unused tap ports or wall plates in the home can actually create a path for ingress and egress, which affects the network performance.

Low cost terminators have a tendency to fail, due to broken center conductors, moisture / corrosion, or both. Just one of these small devices can actually affect the entire upstream data path for many subscribers within that given area and can create costly service calls and lower the quality of experience.

Case studies have shown that terminating all unused tap ports in an average size node can result in a signal to noise improvement of more than 5db in the return path. Inside the home, electrically terminating unused ports on wall plates or actives and passives blocks ingress in the return path as well. Poor electrical terminations caused by moisture migration create havoc on system performance.

Do you know how far you can bend your microduct and fiber?

Posted by Dave Daly

There is a limit to the bending ratio or tight diameter in a microduct or fiber cable - after which, the fiber starts to exhibit failure. The failure can be a slight increase in insertion loss or a "kink" in the fiber that creates a catastrophic effect.  

One of the challenges of installing fiber in the last drop of an FTTH network is knowing the overall distance and the amount of 90 degree angles you can have in the path you will be using. Distance and 90 degree turns create additional friction and add to the cumulative friction.
