EXFO’s TestFlow is a field test automation and analytics solution that efficiently and accurately orchestrates the flow of information throughout critical testing phases during the deployment of fiber-to-the-home (FTTH), fiber-to-the-antenna (FTTA) and distributed-antenna-system (DAS) networks.

Field Test Process Automation

Provides process control and test automation to reduce testing cycles, optimize field performance and accelerate time-to-revenue.

Contextual Analytics

Delivers process visibility through actionable data to effectively ensure compliance to test-process and network-design thresholds.

A Smarter, scalable Way to Test

Manual Process vs TestFlow Process Manual Process vs TestFlow Process

Manual Process

  • Field InefficienciesUp to 50% longer to implement tests

  • Quality issuesMissing and erroneous test information

  • No traceabilityNo consistent method of tracking results

TestFlow Process

  • 85%savings on field entry

  • 50%savings on test time

  • 100%compliant to test process

The TestFlow solution

Leveraging Back-Office Systems and Web-Based Tools to Automate and Orchestrate an End-to-End Testing Process

  • Create intelligent digitized job definitions – predefined test-point IDs, required tests and applicable test configurations for optimized network standards compliance.
  • Distribute jobs to test units and mobile devices.
  • Run consistent job-specific test sequences on test units and mobile devices without the need for other applications or manuals – automated step-by-step tasks and job closeout with dynamic reporting and task-sensitive help for maximized technician efficiency.
  • Automatically upload test results with predefined filenames to centralized TestFlow server for results-to-metrics processing and immediate closeout package audit for completeness.
  • Analyze user-defined testing metrics from centralized TestFlow database and verify compliance with network design standards – automatic test-results analytics and actionable information for visible network testing and proactive management with streamlined work-compliance auditing.
  • Integrate TestFlow server with back-office systems using open application programming interfaces (APIs).

Transforming Field-Testing Operations

With Contextually Relevant Analytics

A Single, Intuitive Application

With Multiple Measurements and Test Points in One Consolidated TestFlow


Link Everything.
Unify All Test Results.

EXFO Link is a mobile application designed to aggregate data and ease consolidation of test results from EXFO or third-party-vendor test sets.

With EXFO Link, test results can be transferred to a smart device from any test set using a wireless or wired link.

From the smart device, results are sent to a centralized database to facilitate consolidation of files from multiple sources into one location.

TestFlow and EXFO Link

Case Study


  • Consistency/quality from multiple subcontractors for fiber-to-the-home (FTTH) installation
  • Significant and error-prone post-testing processing


  • Ensure compliance by enforcing correct pass/fail thresholds for fiber construction
  • Step-by-step guided process for subcontractors’ technicians
  • Automated bidirectional post-testing processing of on-site test results


  • Ensures compliant first-time-right builds
  • Significantly reduces overhead attributed to high-volume test results administration
TestFlow Case Study FTTA


  • Over 40 tests per tower and many test types (e.g., FIP, iOLM, CPRI and RF)
    • iOLM – intelligent Optical Link Mapper
    • CPRI – Common Public Radio Interface
    • RF – Radio Frequency
  • Missing/incorrect test-point labels, missing tests and wrong pass/fail thresholds
  • Confidence in fiber-to-the-antenna (FTTA) construction quality for over 20 contractors


  • One test application – test configurations and test-point IDs are predefined
  • Intelligent, digitized job-specific sequences guide technicians through test process
  • Automated test results upload to track network quality and construction progress


  • Ensures compliant first-time-right builds from all contractors (not just the best)
  • Consolidated results per tower, across all test types
TestFlow Case Study FTTA


  • Optical construction quality/consistency
  • Wide range of link budget thresholds across distributed antenna system (DAS) products
  • Thousands of test results per site, manually spot-checked at best


  • Ensure compliance by enforcing correct pass/fail thresholds for DAS installation
  • Automation of test results analysis with custom and configurable rules
  • Identify issues requiring resolution while the contractor is still on-site


  • Benchmarks contractor performance (network quality and technician efficiency)
  • Ensures compliant first-time-right builds
  • Faster deployment through proactive management
