Why every home should have a MoCA filter

Posted by Krista Tysco

Cable and Internet providers around the world have been challenged by today’s technology demanding faster Internet service and video streaming on their own time.

More cable providers are looking to MoCA (Multimedia over Coax Alliance) in their installations to help with this, but they may not realize they’re missing a key element – MoCA filters installed at every subscriber.

MoCA uses a household’s existing coax cable to transfer data quickly and efficiently throughout the home. A MoCA connection utilizes the unused frequency spectrum offered by coaxial service providers to extend the existing wireless connection to the entire home and cause less demand on the network.

Sounds great! So what’s the catch?

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.

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:

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.

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.
