The Jonard WFM-100 is best understood as a portable fiber end-face probe.[1] It is not a substitute for certifying an optical link. It sends a live image to a phone or tablet over Wi-Fi, then lets the companion app inspect the connector against selected parameters. Jonard’s product page identifies this as the UPC-adapter version and says it inspects male and female PC/UPC SC, ST, FC, and LC connectors with five included adapters.[1] That makes the WFM-100 a plausible field tool for technicians who need a documented end-face check without carrying a dedicated display.
The important trade-off is the host device. The probe is the hardware; the phone, tablet, operating system, wireless connection, app availability, and local IT policy are part of the workflow. If your team wants a single box that boots into an inspection screen, this is the wrong shape of product. If your team already carries supported mobile devices and values image capture plus configurable grading, the design is more compelling.

What the kit and workflow actually provide
The maker describes the WFM-100 as a Wi-Fi end-face probe that provides real-time images on a smart mobile device or tablet.[1] The manual says the probe can capture and save images through the FiberCheck app, and lists manual focus, Wi-Fi/USB connectivity, a USB-C port, a 1280 × 1024 image resolution, and 200X magnification.[2] Jonard lists a USB-C cable, charger, instruction manual and carrying case with the probe and adapters; a compatible phone or tablet is separate.[1] The supplied adapters cover 2.5 mm FC/SC/ST male, 1.25 mm LC male, 2.5 mm FC female, 2.5 mm SC female, and 1.25 mm LC female connectors.[2]
The documented workflow requires a compatible app, a connection to the probe’s Wi-Fi network, the correct connector adapter and manual focusing.[2] This is not a review of tested setup time. The manual explicitly warns that a fuzzy or blurry image causes the test to fail.[2] A failed result therefore does not automatically establish that the connector is contaminated or damaged; focus and image quality also matter.
The app adds a parameter layer rather than merely showing magnified video. The manual says users can choose default parameters or create new ones by entering fiber specifications and threshold limits.[2] After the test, the Results screen can save the test as an image; on iPhone, the manual says saved files go directly to Photos.[2] The documentation does not establish PDF, CSV, cloud, or multi-user report export, so buyers who need those deliverables should not assume they are included.
Modern app naming is the main purchase caveat
The printed/manual workflow still calls the software “FiberCheck.” The current iOS listing recovered for this review is named Jonard Fiber, is published by Jonard Industries Corp., and requires iOS/iPadOS 15.6 or later.[3] The listing describes live Wi-Fi camera video, test and result functions, configurable parameters, and screenshot capture.[3] Its presence does not prove that a particular older iPhone or iPad, an organization’s managed-device policy, or a future OS release will work with this probe; we have not tested an app installation or connection to the probe.
Android requires more caution. The manual QR destination resolves to a third-party PGYER page for FiberCheck 1.4.8, build 2.[6] That page flags the build as not the latest; the linked newer page is named Jonard Fiber 1.4.9, build 3.[4] PGYER itself labels the app as third-party and tells users to screen the risk before installing.[4] Jonard’s own download archive also contains a file titled “WFM-100 Andriod V 4.8.zip,” but that filename is not proof of an app version, a current installer, Google Play distribution, or installer integrity.[1]
That leaves a practical pre-purchase checklist: confirm the exact supported iOS or Android build with Jonard, verify that your phone or tablet can join the probe’s Wi-Fi network, and ask your organization’s IT administrator whether the approved Android deployment path is acceptable. This review does not recommend sideloading an APK, and it does not provide a security assurance for a third-party-hosted Android installer. A buyer who cannot clear those deployment questions should skip this model even if the optical workflow otherwise fits.
Who should buy it—and who should skip it
Buy the WFM-100 when your need is mobile-hosted inspection of one UPC/PC adapter family, quick end-face images, and pass/fail grading against chosen parameters. The five included adapter types make it practical for common SC, ST, FC, and LC inspection tasks, while the separate phone/tablet workflow can be convenient for technicians who already document work on a mobile device.[1][2]
Skip it if you need active-fiber authorization, optical-loss or power measurement, wavelength analysis, OTDR traces, network certification, or a proven audit-report pipeline. A pass/fail result for selected image thresholds is not the same thing as laser-safety verification, link certification, insertion-loss measurement, or an OTDR measurement. The available documentation also does not establish independently tested accuracy, range, battery endurance, or grading latency. Jonard lists a 3-hour battery life and 100 m Wi-Fi range, but those are maker specifications rather than bench results.[1][2]
The WFM-100 is therefore a fit decision about workflow, not a magnification upgrade. Its value depends on whether your team can support the mobile host and the current app path. Confirm the software deployment first; then decide whether a wireless probe, saved images, and parameterized end-face grading justify the purchase.
