Fiber Optic Equipment: How Homologation Works!

Fiber optic equipment are essential elements for high-speed networks and these types of equipment need to be approved by the National Telecommunications Agency, Anatel, to be used in Brazil. 

In this article, we will discuss the basic requirements for the approval of this type of equipment for use in the country.

Fiber optic equipment: What are they?

For a fiber optic network to work properly, it is necessary to invest in the purchase of equipment compatible with the service. After all, they will be the ones that will ensure a great connection speed, as well as support for simultaneous devices. See below.

Cable drop

It serves to give access to the network to the subscriber. This cable is composed of an ITU-T G.657A2 standard fiber, which has a curvature suitable for tight ducts. 

CTO (Optical Termination Box)

It's equipment designed to serve multiple subscribers at once —up to 16 cells. It also supports optical adapters and can be installed with or without splitters. 


Passive component that serves to divide the optical signal. Thus, it allows the P2MP topology, which leaves the network with more capillarity and increases branching. 

Fiber optic network connector

They act as the interface between the devices of an optical network and the fiber optic connection of a cable. In this sense, the connector connects the cables to splitters, adapters, ONUs and others. 

Fiber adapter

Its function is to join two connectors, increasing the accuracy of the optical signal. They are also used in other network components, such as seam boxes and optical internal distributors. 


Optical Network Terminal or Optical Network Unit transforms the optical signal into electrical signals so that the customer can use the network. 

Fiber optic equipment: Why you need Anatel certification

All equipment used in the field of telecommunications — those that use radio frequency, bluetooth or wi-fi — needs certification. 

In this category, there are also devices that help in the operation of communication devices, such as cables and batteries. According to the agency, the certification serves to prove that such objects meet technical and quality requirements:

  • operate at frequencies compatible with the Brazilian standard;
  • not interfere with other regulated services, such as air traffic and cellular networks;
  • introduce constructive characteristics that ensure the safety of users, reducing the chances of electric shocks, explosions, leaks of toxic materials and others.

Fiber equipment that requires anatel approval

According to Anatel's guidelines, all equipment involved in telecommunications must go through a process called homologation. 

The approval ensures that the products marketed are in accordance with the minimum standards of quality, operation and safety required by Anatel.

All elements of the fiber optic network are within the definition of telecommunications products, so each of these elements requires approval separately from tests and standards defined by the Brazilian agency. 

OCDs are independent bodies delegated by Anatel to conduct such processes, and assist manufacturers and importers to obtain homologation of equipment, such as fiber optics. 

One of the most recognized OCDs currently is Master Certifications, which has been present in this market for more than 15 years.

Anatel divides products into different categories according to their purpose within the network, and the elements of a fiber network are included in categories I and III.

Fiber Optic Equipment in Category I

Category I encompasses products that are required to access telecommunications networks such as terminals, but also includes some cables

The elements that belong to the fiber network that you will find in this category are passive optical equipment, such as optical network terminals known as ONT, as well as self-sustaining fiber optic cables – Optical Drop for 80 m spans, compact fiber optic cables for internal installation and microcables.

Fiber Optic Equipment in Category III

Category III is related to equipment that supports telecommunications services and ensures both its reliability and electrical safety, and electromagnetic compatibility. 

The vast majority of fiber optic network equipment are listed in this category, which are:

  • Splitters;
  • Fiber optic cable;
  • Self-sustaining aerial dielectric core fiber optic fiber optic cable;
  • Optical Terrestrial Cables Marinized;
  • OPGW cables;
  • Optical terminal box;
  • Connector for fiber optics;
  • Splice set for optical cables;
  • Optical fibers of types MM, SM, DS, NZD and BLI;
  • Optical multiplex (WDM/CWDM/DWDM);
  • Optical line termination (OLT) / Optical Network Unit (UN);
  • Optical line termination with or without integrated multiplexer;
  • Interface STM-1, 4, 16, 64 optical.

Although these equipments are grouped in the same category, Anatel establishes different parameters for approval of each element of the network described above. 

The procedures are defined according to the technical specifications of the product and the OCD may provide detailed information on the tests required for the issuance of the certificate of conformity for your product.

Approval standards for fiber optic equipment

In general, the standards used by Anatel to evaluate equipment that is part of a fiber network follow a combination of international standards such as ITU-T, IEC, ASTM, and other standards established by Anatel itself.

Homologation process for Fiber Optic equipment

The approval process is initiated by the manufacturer or importer of the product in Brazil. 

The first step to obtain the homologation of any equipment is the choice of an OCD, which is the body delegated by Anatel to carry out the product evaluation process. 

The OCD shall indicate the specific tests necessary for the type of product, conduct the process and ultimately issue the certificate based on the tests conducted in a laboratory accredited by INMETRO.

Based on the technical specifications of the products, the OCD will recommend to the applicant one or more laboratories that may conduct the tests required by Anatel for product certification

According to Brazilian regulations, most laboratory tests should take place in the national territory, but depending on the technology used or the equipment, the choice of the laboratory can be determined by the OCD. 

In this way, the OCD will indicate the number of samples required for testing, and also any additional documentation to complete the approval process.

Based on the test results, the OCD will issue the Certificate of Conformity for the evaluated equipment and request the registration of the product in Anatel databases.

After these steps, the product supplier receives a final version of the Anatel identification seal and the approval code for the product marking.

Renewal of The Approval

The type-approval process is also conducted by the OCD, which will determine which documents and new tests will be required for the renewal process. 

Generally speaking, category I fiber optic equipment must have its approval renewed annually, and category III should request renewal when there are changes in the hardware or technology of the equipment.

Obtaining homologation at Anatel

The company Master Certifications is an OCD delegated by Anatel to conduct the certification process for any equipment that requires homologation. 

Thus, we deal with the entire process, from the request for documents to the issuance of the Certificate of Conformity.
