During regular visits to telecom rooms and central offices, it has come to our attention that technicians are more aware of the need to clean connectors than ever before. The issues related to dirty and/or damaged connectors have been well publicized, and are reputed to be the fiber network’s #1 enemy.

Webinar of the Week Blog Series | Expanding wireless coverage to eliminate dead zones within a network is a necessity. This is achieved by connecting the mobile backhaul to various wireless architectures, namely remote radio heads (RRH), small cells and distributed antenna systems (DAS). However, even in these wireless infrastructures, the integrity of the physical link remains critical!

LTE technology is touted for its ability to offer increased download speeds to customers along with greater application support. For major wireless carriers, such as AT&T Mobility, who are planning to deploy elements of LTE Advanced network technology in order to increase the capacity of their network available to users, the LTE advantage lies in boosting efficient utilization of the spectrum. So, while increasing users’ peak speeds remains a top priority, meeting their LTE data demands is also an important consideration.

Webinar of the Week Blog Series | Ethernet’s long history is one of reinvention. From coaxial to twisted pair cable, increased bit rates, Gigabit Ethernet interfaces and 10 Gbit/s Ethernet LAN to 100 Gigabit Ethernet standardization, the dominance of this protocol and its relative ease of deployment have enabled service providers to drive up revenues while driving down prices.

Although there was some hesitation in the market around voice over long-term evolution (VoLTE) just a year ago, the tides have now changed and the successes made by early adopters of the protocol have prompted analyst groups such as Infonetics Research to double their growth forecasts for its use between 2014 and 2016.

Webinar of the Week Blog Series | What do cable installers and network operators have in common? They both agree that the majority of their network failures are the result of connector endface contamination. This means contamination should never be underestimated. It is therefore important to understand the impact of contamination, whether it is the result of mishandling, the environment, improper cleaning products or normal wear and tear.

It’s no secret: failing to meet your service-level agreement (SLA) makes all the difference between customer churn and repeat customers. If you aren’t able to guarantee reliability, availability, fast failovers and recovery, customers will simply switch to another service provider.

The following is fact: fiber connectors represent the weakest link of any fiber-optic network and, if contaminated or defective, may affect the performance. For this reason, best practices call for correct connector inspection and cleaning procedures on every fiber connection, and during any manipulations. Although most will agree with this statement, this critical inspection step is often neglected. As a result, bad connectors that have been left behind still account for a large percentage of network failures.
