43-10-connector-comprAs traffic growth soars in mobile networks, operators and network infrastructure vendors face two related but distinct challenges. First, they must seek ways to improve network efficiency in an attempt to transport as much data as possible in limited spectrum. Second, they must do so while justifying capital expenditure (CapEx) and operating expenditure (OpEx) investments.

Download the white paper: Small footprint, big advantages: how 4.3-10 connectors enable the networks of tomorrow.

With these factors in mind, the mobile industry has standardized a new RF connector commonly known as 4.3-10, which is set to supersede the existing 7-16 DIN and N connectors. 4.3-10 connectors have been developed to prevent most of the performance issues inherent to the current 7-16 DIN connector. They are also designed to remove as much complexity as possible in the installation of RF equipment such as feeders, antennas, filters and tower mounted amplifiers.

Miniaturization is a trend not only applicable to antennas but to other RF equipment including remote radio units. 7-16 DIN connectors today occupy a significant amount of space in these units, making them a potential obstacle in the path of equipment evolution over the next few years. This is particularly evident in small cells. With a significantly smaller footprint, the compact 4.3-10 connector will improve port density in both macro and small cell RF radio products.

The 4.3-10 connectors have a weight reduction of up to 60 percent and space reduction up to 40 percent. To learn more about 4.3-10 connectors, check out the new white paper, Small footprint, big advantages: how 4.3-10 connectors enable the networks of tomorrow. It describes the key characteristics of 4.3-10 connectors and how they can help operators boost capacity and control costs in the deployment of new sites and evolution of existing sites.

Hi Pedro, when will we see some field fit connectors for 1/2" Superflex, 1/2" Regular coax and 7/8 coax?

Thanks Derek,

They are released now.

I would appreciate if you can share below:

1. Detail differences between 7-16 vs 4.3-10.
2. Performance from field measurements, impact on 2G, 3G and 4G on multiport antenna.
3. How equipment vendors are ready with this initiatives for supporting new connectors.

Hello Isteehad.

Thank you for your questions. Some answers below:

1) Key differences are explained in the whitepaper which can be downloaded from the post. Let me know if there is anything in particular which is missing or without the expected level of detail.
2) Some initial measurements can be observed from vendors. Dynamic PIM performance in CommScope’s jumpers is improved by 3dB compared to the traditional 7/16 based jumpers. As the size of the connector is smaller it will also be easier to deploy/install multiport antennas.
3) Major OEMs have already available 4.3-10 based radios and we expect it to continue. However it will take many years for the complete migration in the field so mixed jumpers are available in the meantime to facilitate the transition.
