Full-fledged units at both ends

Both the main and remote units are full-fledged to maximize the efficiency of each technician:

  • FasTesT™ results with diagnostics are displayed on both units at the end of each test.
  • Both technicians can certify the fiber connectors with an fiber inspection probe via the large touchscreens available on the both units.

With the MAX-945 Fiber Certifier, the remote technician is no longer blind and more efficient.

Onboard assistance and diagnosis

The MAX-945 Fiber Certifier provides a foolproof method against test cord reference mistakes and negative loss thanks to its step-by-step wizard that guides technicians along the referencing and the verification process, as per industry standards. The MAX-945 Fiber Certifier goes even further by diagnosing the possible causes of fail results and gives guidance to fix issues.

Three-year peace-of-mind warranty and calibration interval

The MAX-945 Fiber Certifier has been rigorously tested to guarantee the highest standards of reliability and durability. That is what makes us confident in offering a warranty and a recommended calibration interval of 3 years.

You can safely use this highly reliable instrument to get accurate test results, while significantly reducing your certifier’s cost of ownership (your cost of calibration and the related downtime will be divided by a factor of three).

Multistandard fiber certification

The MAX-945 Fiber Certifier lets you certify against both cabling and application standards at the same time. You can therefore certify the cabling–the physical quality of the fiber and its components like the splices and connectors–as well as the application that the fiber can carry, such as TIA-568, IEEE and or Fibre Channel.

Tablet-inspired design

With the most user-friendly display in the industry (7-inch, high-resolution touchscreen), the MAX-945 Fiber Certifier delivers unprecedented user experience. Its integrated Wi-Fi/Bluetooth allows for high connectivity. The MAX-945 Fiber Certifier guarantees a full day of fieldwork with 12 hours of battery autonomy and internal memory capacity for over 200,000 test files.

Built-in encircled-flux compliancy

Each MaxTester 945 Fiber Certifier comes with a built-in Encircled-Flux (EF) compliant multimode light source. Furthermore, in order to maximize measurement accuracy and avoid invalid results, EXFO designed reference-grade test cords in compliance with the ISO/IEC 14763-3 standard requirements.

EXFO’s test cords are made from reference-grade connectors, and the fiber used is strictly controlled to ensure proper core size and geometry. For multimode testing, this allows to maintain EF-compliancy at the output of the test cord as required by the industry, without the need for an external EF-mode conditioner. These high-quality reference-grade test cords are less fragile and less expensive than EF-compliant test cords, helping to reduce your overall equipment cost of ownership.

EXFO’s test cords are also color-coded to avoid manipulation errors when they are connected to the test ports and device under test. The user interface displays animated instructions with the same color codes to facilitate the test process.

Optical plug-and-play options

The MaxTester 945 features plug-and-play optical options that can be purchased whenever you need them, at the time of your order or later on. In either case, installation is a snap you can do it by your own, without any software update required.

Visual fault locator (VFL)

The plug-and-play VFL easily identifies breaks, bends, faulty connectors and splices, in addition to other causes of signal loss. This basic, yet essential troubleshooting tool, should be part of every field technician’s toolbox. Visually locating faults by creating a bright-red glow at the exact location of the fault on singlemode or multimode fibers, it can detect faults over distances of up to 5 km.

Quad option for multimode units

The MAX-945 Fiber Certifier multimode units offer maximum flexibility by featuring a unique quad-ready ability. Upgrading to the quad option is easy and instantaneous; thanks to a software key that activates the singlemode wavelengths. Singlemode wavelengths are pre-calibrated at the factory, so you are ready to test singlemode fibers right after the upgrade with no other constraints. This will save you both time and money.

Fully automated fiber inspection probe

Neglecting to clean, inspect and certify connectors can lead to serious, time-consuming problems accounting for up to 80% of network failures.

With its two full-fledge units, the MAX-945 Fiber Certifier lets you certify connectors at both ends of the fiber, in the same workflow as the tier-1 certification. It is now easy to include connector certification in your regular method of procedures without compromising the efficiency of your technicians. You’ll no longer leave a stone unturned nor a connector uninspected!

Years of experience in the field have given EXFO the insight and the expertise to re-engineer a truly unique and innovative fiber inspection probe to greatly simplify and speed up this critical step.

Housing a unique automatic focus adjustment system, the FIP-400B automates each operation in the sequence of inspecting a connector endface. The result: fiber inspection is now a quick, one-step process that can be performed by technicians of all skill levels.
