Installing data networks using LinkWare Live SaaS
By  Staff Writer Published  December 20, 2017

Nowadays Software as a Service (SaaS), or the cloud, affects many work processes. The field of measurement technology is no exception.

At the same time test limits, scope of the test, cable IDs and the cable types for the next project, beginning in two days' time, are transferred to the field tester as well. New project details are defined in advance by the project manager and entered into the SaaS via a web interface.

Given the fact that the project manager typically has knowledge of and access to all the project details, including AutoCAD drawings, tender documents, functional specifications, minutes of meetings and last-minute amendments, he is in the best position to define all the test details.

A SaaS for the management of both projects and the cable tester, that also supports list imports of cable IDs from popular tools like AutoCad and VISIO, not only enhances efficiency but also helps prevent errors. The advantage of such a workflow is obvious if we look at experiences from the past: it was frequently necessary to re-test an entire or a large portion of a project because the first time around the technician had selected the wrong Pass/Fail limits or saved the results using an incorrect cable ID.

The Big Wastes

Often cable testers are compared by the time it takes to test a single link. This parameter is important but not essential because if we would assume that a link could be tested twice as fast than before, it would not result into projects being tested in half the time. It's like driving a car; time is not gained when speeding on the free highway, instead it is lost in traffic jams. This means one is better off to prevent or avoid traffic jams.

Back in 2012, 800 installation companies were asked where they experienced wastes of time when certifying newly installed copper and/or fibre structured cabling systems. Replies coming from installers operating in America, Europe and Asia revealed similar patterns. The information was also relevant as these 800 companies installed and tested more than 1 million links a month.

1. Incorrect test limit (Copper): Copper

2. Result saved using the wrong cable ID: Copper & Fiber

3. Reconciliation of test results: Copper & Fiber

4. Setting up the tester (technician waits for foreman): Copper & Fiber

5. Interpretation of OTDR traces: Fiber

6. Incorrect test limit (Fiber): Fiber

7. Test result shows a "Negative Loss" (and is therefore rejected by customer): Fiber

8. Troubleshooting of failing links: Copper

The above lists shows most common time wasters that installers experience when certifying newly installed copper and fiber based structured cabling systems. The lion's share belongs to a category that we could call "Configuration and Administration". If we are able to prevent these instances the potential gain in efficiency and reduction of cost will the highest. A workflow which is supported by a SaaS and field testers that are able to communicate and exchange project details and test results with the same SaaS, has the biggest potential to lead to efficiency gains that will result into project cost savings.

This enhanced workflow is possible because all involved team members can focus on work in their area of expertise. The project manager focuses on the test and quality plan, which involves test regimes, limits and standards as well as Cable IDs and naming schemes. In the final stage, the SaaS will also assist the project panager in producing the necessary documentation which is often the last milestone before customer invoicing occurs. This leaves the technician to focus on what he was trained to do best; test and troubleshoot.

A cloud-based SaaS does not need to be limited to the "store & forward" of test results and the ability to pre-define project specific test configurations. The following two examples illustrate that there are more opportunities to enhance the project flow and increase profitability.

Unexpected Cable IDs: Ad-hoc changes often occur during a project, which result in additional or modified links to be installed. If the SaaS is able to flag unexpected additional links or links with a modified ID, the Project Manager can add them to the project and ensure that documentation is updated and the additional outlay is included in the billing of the project.

Asset Management: Avoid unnecessary project delays by tracking the last used location and monitoring the status of all testers to ensure they are always calibrated and running the latest firmware. The certification measurement report usually forms the basis for the award of a system warranty by the manufacturer of the cable installation system. This system warranty is essential for the end-customer but the manufacturer will only grant it if the tests were performed with equipment with a valid calibration. Test equipment often contains multiple measurement modules with different dates of purchase and expiration dates for the calibration status. The SaaS Asset Management tool issues an alert before the calibration expires, making it is possible to schedule a calibration at a time of reduced project activity. As a result, the risk is eliminated that a project cannot be successfully completed because the manufacturer rejected the request for a system warranty due to the usage of instruments with an expired calibration status.

A day in the life of a data network installer:

10:00 Almost the entire first floor, containing over 300 links, has been tested. By the time he goes for his coffee break, the installer has activated the access point on his SmartPhone and enabled the Sync function on his cable tester. As a result, all the measurement data is now being transferred and immediately available to the Project Manager in the central office.

11:00 The Project Manager uses his SmartPhone web browser to check project progress and from an bird's eye view observes the following:

  • Most of the links on the first floor have been tested which means the project is on track.

  • The Statement of Work requires that all links show a minimum margin of 3dB.

13:00 The remaining links on the first floor were tested and also testing of the second floor was completed. Two of the links were initially below expectations but after reworking the termination the second test demonstrated the expected performance and results were uploaded to the SaaS.

15:00 The Project Manager synchronizes the most recent test results. The status summary demonstrates that testing on both floors is now 100% completed and a quick check reveals that two links had to be reworked to meet the statement of work criteria. In the next step he will create the project documentation. The invoice to the end customer will then follow in the final phase of the project.


The potential productivity enhancements that can be achieved by deploying the LinkWare Live SaaS in combination with instruments that are part of the Versiv Cabling Certification System are substantial:

  • Immediate remote results exchange capability eliminates the need to chase up test results.

  • Incorrect test configurations can be prevented ensuring certification jobs are done right first time.

  • Any unexpected cable IDs are immediately flagged highlighting ad-hoc changes in the field and eliminating cumbersome problem-solving after job completion.

  • 100% testing of a project is ensured.

  • Instrument utilization is optimized as they can stay out in the field and directly roam from project site to project site.

  • The location of each tester can be tracked at any time and as a result a tester can be assigned to a technician on a timely basis.

  • Accelerated documentation leads to warranty statements being promptly issued and installers being paid sooner.

Complying with Privacy Guidelines: Cloud-based services are often associated with security risks. To put the risk in perspective an example from an adjacent sector can be used: The humidity and temperature in every room of a new bank building are recorded and transferred to a SaaS as part of the acceptance procedure for the newly installed air conditioning and heating. It is unlikely that someone gaining access to this information would be able to misuse it in any way. The same is also true for data relating to cryptic cable IDs, NEXT, repeat length (RL) and insertion loss margins.

However, this does not mean that there is no need for the SaaS to meet the national, and international regulations for safe data havens. The LinkWare Live privacy guidelines are clearly formulated as part of the terms and conditions for the usage of the SaaS.
