The consequences of coaxial connector problems

Posted by Dave Daly

In the modern world, we need our broadband to work fast and reliably - download speeds and picture and voice quality are what we as consumers care about most. This creates an explosion of demand for network capacity in broadband, satellite, telco and security networks.

Today’s coaxial connectors have to be high-performance and provide nearly flawless signal transmission to accommodate the very large amounts of traffic going back and forth from provider to end user.

Bonding and Grounding for CATV – What's the Difference?

Posted by Dave Daly

Bonding is the electro-mechanical joining of two or more conductors, to form a conductive path that ensures electrical continuity. Grounding is connecting a circuit to the earth or to another conductor that is itself connected to earth. 

Broadband cable systems are usually connected to ground to limit the voltage potential between the cable sheath in the house and the other grounded items in the house, including water pipes, appliances and anything else connected to the utility.

A cable not properly grounded can have a high electric potential when compared to the utility ground in a house. Grounding the cable system to the same ground used by the utility minimizes voltage that could exist between them.

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.

Overcoming Hidden Costs in the Broadband Network's Last 200 Feet

Posted by Rick Haube

Many people involved in broadband network deployments appreciate that there could be "hidden" costs down the line because less expensive products have been chosen upfront, for use in the critical transmission path close to the subscribers. The real issue is how to balance slightly higher capital costs for quality components and training, against true savings in operational costs. 

Substandard components are apt to need replacement sooner than those of higher quality - not to mention the costs resulting from the poorer performance profiles of low-quality products.

But what of the hidden costs associated with a poorly or improperly trained workforce? These costs appear in the form of more service calls and repeat service calls.

How to understand price and value in broadband networks

Posted by Rick Haube

In managing the infrastructure of broadband networks, an often underacknowledged element is the coaxial cabling and connectors required to deliver the very services your customers pay for.

Research shows that possibly the most significant issue for service providers is service calls in "the last mile" (or "the last drop") - the connection from the end of the distribution network up to and including the customer premise equipment.

The research indicates that the leading cause of service calls, as much as 40 percent, is due not only to improper installation of coaxial cable and connectors, or simply loose connectors, but also that the connectors being employed are of sub-standard quality within the environment, affecting electrical and mechanical performance. This has historically been such a chronic issue that some operators have come to accept it as a cost of doing business.

Broadband Subscribers' Self-Installations: Getting it Right First Time

Posted by Dave Daly

A growing number of broadband subscribers are being given the option of installing or reinstalling customer-premises equipment (CPEs) themselves, with the help of self-install kits (SIKs). For the subscriber, this can lead to flexibility, autonomy, and independence when setting up their information and entertainment environments. Sometimes, however, it can lead to problems - and expensive service calls. 

Compared to the first generation of SIKs some twenty years ago, today's options are much improved and standardized. The original SIKs often contained a bewildering array of cables, connectors, and passives, including composite video cables, component video cables, HDMI cable, coax cable, audio, category cable, RF splitters and others. 

The matrix of possibilities was endless and confusing but with the standardization of connection devices for CPEs, the list is now more specific and sophisticated, including usually only coax cable, HDMI and category cable, depending on the services purchased. 

So, how do you make sure self-installations are done properly?

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.
