What is Network Certification for?<\/h2>\n\n\n\n
Network Certification<\/strong> serves as a validation that the structured cabling project was executed correctly, from its conception to its implementation, ensuring that technical criteria were met at all stages of the process and that key sectors will not suffer from a lack of communication.<\/p>\n\n\n\n Structured Cabling Certification<\/strong> provides the assurance that the installed cabling system will meet the specified performance requirements, avoiding rework, costly adjustments, and operational problems resulting from infrastructure failures.<\/p>\n\n\n\n Network Cabling Certification<\/strong> tests are performed with specialized equipment, such as cable testers and network analyzers, which measure the system’s capacity to support certain data transmission speeds, according to the category of installed cables.<\/p>\n\n\n\n These tests are conducted in accordance with Structured Cabling Technical Standards<\/a>. Passing the certification tests ensures that the cabling infrastructure meets the minimum requirements for applications compatible with its category, guaranteeing consistent and reliable performance for the network.<\/p>\n\n\n\n To perform the certification of twisted pair cables, a Network Certification Device<\/a> is used, consisting of two units: a main unit and a remote unit.<\/p>\n\n\n\n These units are connected to the ends of the cable to be tested.<\/p>\n\n\n\n During the procedure, the main unit generates and transmits an electrical signal that travels the entire length of the cable to the remote unit. The remote unit, in turn, receives the signal and performs a detailed analysis, examining several critical parameters for performance.<\/p>\n\n\n\n The twisted pair cable certification process involves the measurement and analysis of several physical and electrical parameters to ensure proper cable performance and data transmission quality.<\/p>\n\n\n\n The parameters measured during twisted pair cable certification include:<\/p>\n\n\n\n Network Certification<\/strong> is only complete when all measurements meet the performance limits specified by the standards, ensuring that the structured cabling system is in full compliance and ready for use.<\/p>\n\n\n\n Understanding how insertion loss, return loss, crosstalk, and propagation delay values impact transmission performance is fundamental to interpreting test reports and verifying regulatory compliance.<\/p>\n\n\n\n To technically understand how these parameters are measured and how each affects certification, read the technical article on Test Parameters for Twisted Pair Cable Certification<\/strong>.<\/p>\n\n\n\n Check it out \u2192 Test Parameters for Twisted Pair Cable Certification<\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n For performing Network Certification tests on twisted pair cables<\/strong>, technical standards (ABNT NBR 16869-3, ISO\/IEC 11801, and ANSI\/TIA-568.2-D) define different configuration methods according to the adopted topology.<\/p>\n\n\n\n Point-to-point links<\/strong> are the transmission path “from one end to the other”<\/strong> within the structured cabling, including the connections at both ends<\/strong> and any intermediate connections intended for that link.<\/p>\n\n\n\n It is the transmission path formed by cables and connections at both ends, following the traditional structured cabling philosophy (patch panel \u21c4 telecommunications outlet).<\/p>\n\n\n\n The Permanent Link<\/strong> corresponds to the certification of the fixed part of the structured cabling, covering the section between the rack’s patch panel and the telecommunications outlet or consolidation point.<\/p>\n\n\n\n This method excludes patch cords and equipment cords and is considered the main form of installation acceptance, ensuring the compliance of the passive infrastructure.<\/p>\n\n\n\n The Channel<\/strong>, in turn, represents the certification of the complete communication segment, including all patch cords, equipment cords, and necessary connections between active equipment.<\/p>\n\n\n\n This test reflects the actual performance of the operating network and is recommended after the permanent link test, allowing to validate the final performance of the installation.<\/p>\n\n\n\n With the evolution of standards, the Modular Plug Terminated Link (MPTL)<\/strong> was introduced, designed for situations where the horizontal cable is terminated on one side in a patch panel and on the other in a male RJ-45 plug connected directly to the end device, such as IP cameras, access points, or IoT equipment.<\/p>\n\n\n\n This method eliminates the need for telecommunications outlets and additional cords, being tested with a combination of a permanent link adapter on one end and a patch cord adapter on the other, in order to also certify the quality of the field plug termination.<\/p>\n\n\n\n Direct Connection Cabling<\/strong>, also known as Direct Attach or End-to-End (E2E), consists of a cable terminated directly in plugs at both ends, without a patch panel or intermediate outlets, and is accepted in short and dedicated links, such as interconnections between switches or between switch and server in the same rack.<\/p>\n\n\n\n In industrial applications, ISO\/IEC defines specific limits for M12 connectors.<\/p>\n\n\n\n The NBR 16869<\/strong> is the latest ABNT standard that establishes the technical requirements for structured cabling, covering everything from planning and installation to the test methods applicable to the certification of metallic and optical cable systems.<\/p>\n\n\n\n To understand in detail the provisions of this publication and its practical application in the deployment and certification of network infrastructures, read the complete article on the ABNT NBR 16869<\/a>.<\/p>\n\n\n\n See also:<\/p>\n\n\n\n After executing the certification tests, a detailed report is generated that documents all measurements, analyses, and results of the tested parameters.<\/p>\n\n\n\n This report should be included in the as-built project documentation<\/a>, serving as a technical reference for future interventions, such as maintenance, upgrades, and network expansions.<\/p>\n\n\n\n Certification documentation facilitates infrastructure management and contributes to a reliable installation history, helping to identify needs for improvements or adjustments over time.<\/p>\n\n\n\n To perform the certification of fiber optic cables, an Optical Power Meter and an OTDR (Optical Time-Domain Reflectometer) are used, which are specific equipment to analyze the transmission parameters of optical cabling.<\/p>\n\n\n\n Fiber cable certification involves the measurement of several optical parameters to ensure signal transmission quality and compliance with standards.<\/p>\n\n\n\n The main parameters checked during the optical cable certification process include:<\/p>\n\n\n\n To perform Network Certification<\/strong> tests for fiber optic cables, the standards define two main levels: Tier 1 and Tier 2.<\/p>\n\n\n\n Tier 1 certification involves checking polarity, measuring attenuation, and link length. This procedure is performed using a light source and an optical power meter (PM\/LS).<\/p>\n\n\n\n The Power Meter measures the power of the optical signal that reaches it, comparing it with the power from the light source to calculate the attenuation. The results are then compared to the limits defined by the standards to verify if the optical fiber meets the minimum performance requirements.<\/p>\n\n\n\n Tier 2 certification provides a detailed analysis of link integrity through the use of an OTDR (Optical Time-Domain Reflectometer).<\/p>\n\n\n\n The OTDR sends pulses of light along the fiber and measures the backscattered light (reflected back).<\/p>\n\n\n\n Based on the time and intensity of the returned light, the OTDR generates a trace that shows all loss and reflection events along the length of the fiber, identifying the precise location of faults or problematic components, such as poorly executed splices or defective connectors.<\/p>\n\n\n\n The objective of fiber optic certification may vary according to network specifics and the operational requirements of the final application. In most cases, the focus is on verifying if the total link loss is within the limits allowed for the application, rather than individually assessing the quality of each splice or connector.<\/p>\n\n\n\n For this reason, Level 1 certification is mandatory, while Level 2 certification should be used as a complementary tool, applied in cases where a more detailed analysis of events along the link is necessary to ensure network integrity.<\/p>\n\n\n\n Network certification<\/strong> is an essential practice to ensure the efficiency and reliability of any organization’s telecommunications infrastructure.<\/p>\n\n\n\n With it, it is possible to ensure that network components are aligned with the quality specifications required by the industry, minimizing risks and providing significant benefits:<\/p>\n\n\n\n By mitigating critical problems such as low speed, connectivity failures, and service interruptions, structured cabling certification ensures that users have continuous and efficient access to network resources.<\/p>\n\n\n\n This translates into faster operations, greater employee satisfaction, and reduced time spent on maintenance and troubleshooting, allowing focus to be directed to strategic areas such as innovation and sustainable growth.<\/p>\n\n\n\n Investing in Network Certification<\/strong> is proven to be an efficient strategy for optimizing operational costs.<\/p>\n\n\n\n According to studies by BICSI (Building Industry Consulting Service International<\/a><\/em>), preventive certification can reduce maintenance costs by up to 30% over the network’s lifespan.<\/p>\n\n\n\n Through detailed diagnostics, problems such as signal degradation and connectivity failures are identified and resolved before they become critical, minimizing the need for emergency interventions and significantly reducing network downtime.<\/p>\n\n\n\n Network certification is a prerequisite required by cabling manufacturers for the granting of extended warranties, which can last from 10 to 25 years, according to the terms established by leading manufacturers such as CommScope, Panduit, and Furukawa.<\/p>\n\n\n\n These warranties apply to networks installed and certified by qualified professionals, providing the end user with technical support and coverage for repairs and replacements in the event of potential failures.<\/p>\n\n\n\n In addition to the immediate benefits, network certification prepares your infrastructure for future expansions and technological upgrades.<\/p>\n\n\n\n With a certified network, your company will be ready to integrate new technologies, ensure scalability, and quickly adapt to market changes.<\/p>\n\n\n\n When choosing a company to perform your business’s network certification, it is fundamental to keep some essential precautions in mind. These precautions will help ensure that the certification process is conducted correctly, providing the benefits mentioned above. Here are some crucial factors to consider:<\/p>\n\n\n\n Ensure that the company has solid and proven experience in the market, with a history of working on relevant projects and properly qualified professionals.<\/p>\n\n\n\n Carefully analyze their success cases, service portfolio, and any technical documentation that demonstrates the company’s expertise.<\/p>\n\n\n\n Evaluating these materials is essential to ensure that the procedures adopted follow industry best practices.<\/p>\n\n\n\n Ensure that all measurement equipment used by the company is properly calibrated according to current technical standards.<\/p>\n\n\n\n Always demand the calibration certificate, which is an official document proving the precision and compliance of the equipment used.<\/p>\n\n\n\n Periodic and certified calibration of measurement instruments is crucial to ensure the accuracy of the results and minimize the margin of error, ensuring that the assessments performed are reliable and faithfully represent the condition of the network.<\/p>\n\n\n\n It is essential to validate the authenticity and integrity of certification reports, especially PDF files generated directly by the testing equipment.<\/p>\n\n\n\n Reports edited after tests are performed can compromise the veracity of the data, including critical information such as the validity of equipment calibration and the compliance status of tested points.<\/p>\n\n\n\n To ensure the integrity of the results presented, demand the original file generated by the equipment, avoiding manipulations that could distort the analysis and compromise the reliability of the certification.<\/p>\n\n\n\n In short, it can be stated that Network Certification plays a fundamental role in guaranteeing the quality, reliability, and performance of a Network Infrastructure.<\/p>\n\n\n\n By properly performing certification, companies can ensure that the Structured Cabling System meets the technical criteria established by standards, providing a solid foundation for efficient connectivity and communication.<\/p>\n\n\n\n We hope this article has clarified the importance of Network Certification for the efficiency and reliability of your structured cabling infrastructure.<\/p>\n\n\n\n For more information or specialized technical support, our team is available to assist you with the certification and optimization of your network.<\/p>\n\n\n\n Network certification is a process involving a series of tests performed on structured cabling systems to ensure that the network infrastructure meets the performance and compliance standards required by technical norms.
