What This Cheat Sheet Covers (and What It Doesn't)
This page condenses the facts that matter most for the Fiber To Any Antenna (FTAA) certification from ETA International. It is built for the final stretch of preparation: the night before a course module, the week before your knowledge exam, or the moment you want to confirm a number you half-remember. If you are still deciding whether to pursue the credential at all, start with What Is FTAA Certification? and Is the FTAA Certification Worth It? Complete ROI Analysis 2026, then return here.
One scoping note matters. ETA's current competency document discusses the older "Fiber To The Antenna" terminology, but the selected name and official abbreviation are Fiber To Any Antenna (FTAA). The scope is fiber and associated antenna cabling: installation, inspection, cleaning, and testing. It is not a general RF engineering or network-design credential, so do not spend review time on antenna theory or radio planning that the competency document does not list.
The Exam at a Glance
| Item | What the issuer sources support |
|---|---|
| Governing body | ETA International |

Two cautions on that table. First, the exact question format (the item style within the 75 questions) is not established by the public issuer material, so avoid assuming multiple-choice conventions you have not confirmed with your school or test site. Second, you may see a competitor describe a 50-question exam built from four ten-question sections. That description contradicts itself and does not match the issuer page, so ignore it.

The Path to the Knowledge Exam
The sequence is the most commonly misunderstood part of FTAA. ETA's competency introduction places a required special course, its associated fee, and a hands-on examination through an ETA-approved school before the knowledge examination. Remote knowledge testing does not substitute for that hands-on component.
- Enroll with an ETA-approved school. Complete the required course and its hands-on component.
- Demonstrate hands-on competency. This is a required part of certification, alongside the knowledge exam.
- Sit the knowledge exam. 75 questions, two hours, 75% to pass, delivered through ETA Certification Administrators (online or paper/pencil) or remotely via ExamRoom.AI where arranged.
- Maintain the credential across the four-year term.
Cost planning follows from this structure: the US$155 examination fee is one line item, while course tuition from the approved school is a separate and variable amount unless a provider expressly bundles it. The full picture is in FTAA Certification Cost 2026: Complete Pricing Breakdown, and eligibility specifics are in FTAA Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The 10 Major Knowledge Categories, Condensed
The competency document lists ten Major Knowledge Categories. They are issuer competency objectives, not a weighted blueprint, so no category can be called "the biggest." The safest assumption is that all ten are fair game and that the hands-on categories (connectorization, installation, testing) matter in both your skills assessment and your knowledge preparation.
| # | Official category | Cluster |
|---|---|---|
| 1 | Principles of Fiber Optic Transmission | Foundations |
| 2 | Basic Principles of Light | Foundations |
| 3 | Optical Fiber Construction and Theory | Fiber |
| 4 | Optical Fiber Characteristics | Fiber |
| 5 | FTAA Safety | Safety |
| 6 | Fiber Optic Light Sources, Detectors and Receivers | Components |
| 7 | Fiber Optic and Antenna Cabling | Components |
| 8 | Connectorization | Hands-on |
| 9 | Cable Installation and Hardware | Hands-on |
| 10 | Test Equipment and Link/Cable Testing | Hands-on |
For a deeper walk through each area, see FTAA Exam Domains 2026: Complete Guide to All 10 Content Areas. The sections below give the cheat-sheet version.
Light, Fiber Construction and Fiber Characteristics
Domains 1 and 2: Transmission Principles and Basic Principles of Light
These categories establish the vocabulary everything else depends on. Expect to reason about how information travels as light through fiber and how light behaves at boundaries.
- Be able to explain, in plain terms, why a signal is carried as light and what a link needs at each end (a source and a receiver).
- Know the core behaviors of light as they apply to fiber: reflection, refraction, and how these confine light in the core.
- Connect each principle to a field consequence, such as why a dirty or damaged endface causes loss.
Domain 3: Optical Fiber Construction and Theory
This is the anatomy-and-types section. Know the layers of a fiber and how they cooperate.
- Distinguish the parts of a fiber (core, cladding, coating) and the job each one does.
- Compare the major fiber types and when each is used, including why one type suits longer or higher-capacity runs.
- Understand how construction choices influence performance and handling.
Domain 4: Optical Fiber Characteristics
Characteristics are the measurable behaviors that explain why a link performs the way it does.
- Attenuation (loss) and its causes: absorption, scattering, bending, and connection/splice loss.
- Bandwidth and dispersion concepts, and how they limit what a fiber can carry.
- Be ready to link a characteristic to a test result, since this category feeds directly into Domain 10.
Sources, Cabling, Connectors and Installation
Domain 6: Light Sources, Detectors and Receivers
This covers the electronics at either end of the link.
- Know the common source types and what distinguishes them in how they launch light into fiber.
- Understand what detectors and receivers do and what limits their sensitivity.
- Recognize how source and receiver characteristics interact with the fiber when you budget loss.
Domain 7: Fiber Optic and Antenna Cabling
This is where the "antenna" in Fiber To Any Antenna shows up. The scope is the cabling that carries fiber to and alongside antenna installations, not antenna design.
- Know cable construction and types, including indoor versus outdoor distinctions and how environment shapes cable choice.
- Understand how fiber and associated antenna cabling are routed and organized together.
- Keep the scope disciplined: installation, inspection, cleaning, and testing of cabling, not RF or network design.
Domain 8: Connectorization
Connectorization is a hands-on strength area and a common trouble spot, because small process errors create large losses.
- Know common connector types and their typical applications.
- Understand termination and polishing concepts, and why endface quality governs performance.
- Be able to describe the inspect-clean-inspect habit and what a contaminated or damaged endface looks like and causes.
Domain 9: Cable Installation and Hardware
Installation questions test whether you protect the fiber while putting it in place.
- Know the limits that protect cable during pulling and routing, such as respecting bend radius and tension limits.
- Understand supporting hardware, enclosures, and cable management as they apply to antenna sites.
- Connect good installation practice to long-term reliability and to the loss you will later measure.
Testing and Safety: The Practical Core
Domain 5: FTAA Safety
Safety is its own official category, not an afterthought. Expect it to touch both fiber-specific hazards and the realities of working around antenna installations.
- Fiber-specific hazards: invisible light from sources, glass shards from cleaving, and chemical handling during cleaning.
- Work-environment awareness appropriate to antenna-related sites, including safe practices when working around installed equipment.
- Know the protective practices and personal protective equipment that go with each hazard.
Domain 10: Test Equipment and Link/Cable Testing
This category rewards candidates who can match a tool to a task and interpret what it reports.
- Know the main test instruments used on fiber links and what each one is designed to measure.
- Understand how loss is measured on a link or cable and how results compare against a loss budget.
- Be able to reason from an unexpected reading back to likely causes, such as a dirty connector, a poor termination, or an installation-induced bend.
Key Takeaway
Domains 4, 8, 9, and 10 form a causal chain: fiber characteristics define what can go wrong, connectorization and installation are where it usually does, and testing is where you find out. Study them as one story, not four lists.
Test-Day Rules and Retake Policy
ETA's general onsite rules are straightforward, but confirm the rules for your specific delivery method, especially if you arranged remote testing.
- Photo ID is required.
- Personal electronic devices are prohibited.
- Scratch paper is permitted and must be surrendered at the end.
- Calculators: non-programmable or scientific calculators are permitted under the general onsite rules.
- Remote proctoring: where applicable, ETA's two-hour remote-proctoring fee is $16.
- Retake: one free retake is offered within one year of the initial session under ETA's terms. That does not promise free repeat tuition or free remote administration.
- Accommodations require individual arrangement with ETA in advance.
Four-Year Validity and Maintenance
The certification runs on a four-year term. Under the ETA Maintenance with Hands-On route, the requirements are:
- 6 relevant continuing-education hours per year, totaling 24 hours over the four-year cycle.
- Employer verification and the maintenance form.
- A fee of $25 per year, or $100 over the four-year cycle.
- Annual submission is recommended, though the requirements can be satisfied across the cycle.
- Workplace training credit is subject to evaluation.
Keep your records clean from the first year. A running log of training dates, topics, hours, and verifying signatures turns renewal into a form-filling exercise instead of a scramble.
A Domain-Ordered Review Sequence
Because the exam is organized by domain, review is most effective when it follows the dependency order of the content rather than a generic calendar. Here is one sequence that mirrors how the categories build on each other. For a fuller plan, see the FTAA Study Guide 2026: How to Pass on Your First Attempt.
Foundations
- Domains 1 and 2: transmission principles and basic principles of light.
- Build a glossary now; every later domain reuses these terms.
Fiber and Characteristics
- Domains 3 and 4: construction, types, attenuation, bandwidth.
- Pair each characteristic with the field cause behind it.
Safety and Components
- Domains 5 and 6: hazards and protective practices, then sources, detectors and receivers.
- Domain 7: fiber and antenna cabling types and scope.
Hands-On Domains and Practice
- Domains 8, 9, and 10 together: connectorization, installation, and testing as one chain.
- Finish with timed question sets against the 75-question, two-hour format.
Schedule the hands-on domains after the theory ones because testing results only make sense once you understand fiber characteristics. When you reach timed practice, the FTAA practice tests let you rehearse the pacing: 75 questions in two hours leaves a little over 90 seconds per question on average, which is comfortable if you do not stall on any single item. If you are unsure how demanding the exam is, read How Hard Is the FTAA Exam? Complete Difficulty Guide 2026.
Where the Credential Gets Used
FTAA aligns with work that involves fiber and associated antenna cabling: installing it, inspecting and cleaning connections, and testing links. That tends to be relevant to wireless infrastructure contractors, tower and site-services crews, telecom installers, and technicians who maintain fiber-fed antenna sites. The credential signals that a technician has demonstrated both knowledge and hands-on competency in that cabling work.
