AEM FiBLU – App-Native Tier 1 Fiber Certifier

Q: Does FiBLU test network throughput?

No. FiBLU does not generate active Ethernet traffic and does not run BERT, RFC 2544 or Y.1564. It can evaluate whether optical loss fits the budget of a selected application.

Q: Does FiBLU replace an OTDR?

No. FiBLU performs end-to-end Tier 1 certification. An OTDR provides Tier 2 event location, event loss and reflectance. The tools answer different, complementary questions.

Q: Is FIBLU-QD-K01 a single quad tester pair?

No. QD contains four devices: two MM handsets and two SM handsets. This supports dual-ended work on either fiber type.

Q: Can UniBLU work offline?

Yes, for core work. Testing and local storage work offline. Internet access is needed for cloud sync, account features, firmware updates and online services.

AEM FiBLU is an app-native Tier 1 OLTS certifier for MM and SM links. It measures insertion loss and length, evaluates PASS/FAIL and creates the report in UniBLU.

Fiber certification that ends with a ready-to-share report

FiBLU is an app-native Tier 1 OLTS certifier for multimode and single-mode links. Dedicated hardware measures insertion loss and length; UniBLU evaluates the result against the selected limit and takes the project from setup to report.

FiBLU at a glance

The phone is the interface. FiBLU performs the measurement.

The UniBLU app manages projects, limits, users and reports. Calibrated FiBLU handsets perform the optical measurement and communicate with the phone over Bluetooth.

Tier 1 certification

Insertion loss, length and propagation delay, followed by a clear PASS/FAIL result against the selected limit.

MM, SM or both

Separate multimode and single-mode handsets, plus a complete Quad kit containing four devices for both media.

Loopback and dual-ended

Test from one end or between two technicians, including bidirectional dual-ended and simplex workflows.

No manual transcription

Results stay with the UniBLU project. Export options include PDF, CSV and the .ubu project file for TestDataPro.

Core testing works offline

No internet connection is required for testing and local storage. Connectivity is required for sync, accounts and updates.

Field-ready hardware

A compact 177 × 92 × 42 mm enclosure, 350 g weight, USB-C charging and typical operating time stated in the current manual.

Scope and boundaries

What FiBLU measures — and what it does not

FiBLU is a Tier 1 OLTS certifier. It tells you whether total link loss and length are within the selected limit. It does not locate individual fiber events or generate active Ethernet traffic.

Yes — FiBLU

dual-wavelength insertion loss,
length and propagation delay,
PASS/FAIL against the test limit,
optical power meter, source and VFL,
project-based result reporting.

No — use another tester

OTDR event maps and distance-to-fault,
Tier 2 traces, event reflectance and analysis,
active throughput, BERT, RFC 2544 or Y.1564,
PoE, Multi-Gig and copper-layer tests.

For tender specifications: “throughput verification” is not a FiBLU function. FiBLU can evaluate optical loss against an application budget, but it does not perform an active data-transmission test.

Choose the right test class: learn about Tier 1 fiber certification, or use Tier 2 OTDR testing to locate events. For a platform that combines copper and fiber certification, see AEM TestPro CV100.

Select the fiber type. See the correct kit.

Dual-ended operation requires two handsets of the same type. MM-K01 and SM-K01 each include a tester pair, reference cords, couplers and a case. QD-K01 contains four distinct devices: 2× MM and 2× SM.

From reference to PDF

Five stages. One coherent project.

UniBLU guides the technician through project setup, reference setting, AutoTest, result evaluation and reporting. Test duration depends on mode and configuration, so this page does not repeat conflicting numbers found on AEM subpages.

Project and limit

Select fiber type, topology, standard or application budget, and link identification.

Set Reference

Set a 1-, 2- or 3-jumper reference appropriate to the standard and connector types.

Connect

Pair the handsets over Bluetooth and connect cleaned interfaces with the correct TRCs.

AutoTest

Run a dual-wavelength test; UniBLU displays length, loss, margin and PASS/FAIL.

Report

Store the result locally, export PDF or CSV, or sync the project when internet is available.

Canonical specifications

FiBLU MM and FiBLU SM specifications

The values below follow the current UniBLU manual v260803. UniBLU provides workflows and test limits based on TIA-568 and ISO/IEC 14763-3; the applicable reference method and limit must be selected for the specific link.

Technical and buying FAQ

Common questions about AEM FiBLU

What is the AEM FiBLU certifier?

FiBLU is an app-native Tier 1 OLTS certifier for MM and SM links. The hardware measures insertion loss and length; UniBLU manages the project, evaluates PASS/FAIL and produces the report.

What does FiBLU measure?

FiBLU measures dual-wavelength insertion loss, length and propagation delay. It also provides power-meter, light-source and VFL functions and evaluates results against the selected limit.

Does FiBLU test network throughput?

No. FiBLU does not generate active Ethernet traffic and does not run BERT, RFC 2544 or Y.1564. It can evaluate whether optical loss fits the budget of a selected application.

Does FiBLU replace an OTDR?

No. FiBLU performs end-to-end Tier 1 certification. An OTDR provides Tier 2 event location, event loss and reflectance. The tools answer different, complementary questions.

Which kit should I choose: MM, SM or QD?

Choose FIBLU-MM-K01 for multimode, FIBLU-SM-K01 for single-mode, and FIBLU-QD-K01 when one team covers both fiber types. The kit-selection section lists the exact BOM.

Is FIBLU-QD-K01 a single quad tester pair?

No. QD contains four devices: two MM handsets and two SM handsets. This supports dual-ended work on either fiber type.

Can UniBLU work offline?

Yes, for core work. Testing and local storage work offline. Internet access is needed for cloud sync, account features, firmware updates and online services.

Which report formats does UniBLU export?

UniBLU exports PDF reports, CSV data and the native .ubu project file. A .ubu file can be imported into AEM TestDataPro.

Which reference methods does FiBLU support?

FiBLU supports 1-, 2- and 3-jumper reference methods. AEM recommends 1-jumper, but the correct choice depends on the standard, connector types and which connections must be included in the result.

What is included in the K01 kits?

MM-K01 and SM-K01 each contain two handsets of the selected type, two USB-C cables, TRCs, SC and LC duplex couplers, and a soft case. QD-K01 contains four handsets and accessories for both fiber types. A phone and AC/DC wall adapter are not included.

Which operating-system versions are required?

The current v260803 manual requires Android 11 or newer, or iOS 15.5 or newer. Check the current requirements in the manual and app store before purchase because UniBLU releases may change them.

How often does FiBLU require calibration?

The recommended calibration interval is one year. If a quality plan or tender requires a shorter interval, follow the stricter requirement.

Technical data verified on 18 August 2026 against UniBLU User Manual v260803, FiBLU Product Brief 260709, the current AEM BOM and AEM pages published on 16–18 August 2026.
