Fluke Networks Introduces CertiFiber Max for Data Center Fiber Certification
CertiFiber Max is Fluke Networks’ third-generation OLTS, offering native MPO and MMC support and fast multi-fiber certification on the Versiv platform.
Fluke Networks has introduced CertiFiber Max, a third-generation optical loss test set built on the Versiv platform for high-density data center fiber certification. The new OLTS supports native testing of up to 24 fibers in a single cycle, with direct MPO and MMC connectivity that eliminates fan-out cables and adapter chains. CertiFiber Max measures loss, length, and polarity simultaneously, integrates with LinkWare and ProjX workflows, and is designed to reduce setup time while maintaining Tier 1 certification accuracy.

Fluke Networks has announced the CertiFiber Max optical loss test set, which is a third-generation OLTS built on the Versiv platform that provides native support for testing up to 24 fibers in a single measurement cycle. The system supports both MPO and MMC connectors directly, eliminating the need for fan-out cables or adapter chains during multi-fiber certification.
A New OLTS Built for Multi-Fiber Links
Fluke Networks is addressing these constraints with the release of CertiFiber Max, a third-generation optical loss test set designed specifically for high-density multi-fiber cabling. Built on the company’s existing Versiv platform, CertiFiber Max is designed to certify up to 24 fibers in a single test cycle, with measurements completed in under one second.
The tester simultaneously measures optical loss, fiber length, and polarity across all fibers. It integrates directly with Fluke’s LinkWare™ software ecosystem for result storage, reporting, and project management. The goal is to reduce time per link while maintaining consistent test accuracy as fiber counts continue to rise.
Native Support for MPO and MMC Connectors
CertiFiber Max uses field-replaceable UniPort adapters to connect directly to multi-fiber interfaces. The adapters support MPO connectors with 12, 16, or 24 fibers, as well as 16- and 24-fiber MMC connectors, in both pinned and unpinned versions. This also eliminates the need for fan-out cables or connector-specific test setups, allowing the tester to be reconfigured in the field as connector types change.

Because UniPort adapters are field-replaceable, the tester can be adapted as connector types evolve. The adapters also protect the tester’s ports from wear, helping extend tool life in high-volume testing environments.
CertiFiber Max uses the standards-recommended one-jumper reference method, which minimizes measurement uncertainty. The tester includes guided workflows that step technicians through reference setup, track time since the reference was set, and count the number of tests performed with each test reference cord. These checks are intended to reduce errors that can invalidate large batches of test results.
Workflow and Troubleshooting Features
The CertiFiber Max includes tools designed to reduce follow-up work. A built-in multi-fiber visual fault locator can illuminate all fibers in a link simultaneously to help identify breaks or routing issues. An integrated duplex power meter supports SC and LC connectors, and optional end-face inspection tools allow inspection and documentation of both ends of a link alongside test results. The tester works within Fluke’s ProjX management system, allowing jobs to be configured in advance with cable types, limits, and identifiers. Test results can be uploaded from the field using LinkWare Live, reducing the need to recall testers just to collect data.

CertiFiber Max is designed for current data center installations, and the new OLTS will support native multi-fiber connectors and reduce setup steps, which helps keep testing aligned with established workflows. As part of Fluke Networks’ Versiv platform, CertiFiber Max provides Tier 1 fiber certification and ties into existing reporting and project management tools used in the field.
