Established overseas reference products
Official specifications compared by field workflow, not by an invented score. A separate evidence check shows where the supplier-accessible G11 may fit and what remains unproven.
Shortlist when: technicians value a 225 g meter, color touchscreen, USB-C, Bluetooth reporting, and PX1-PRO wavelength automation.
Do not choose on this page alone if: integrated connector inspection or phone-free long-runtime work is mandatory.
Shortlist when: pass/fail connector inspection, power measurement, certification reports, and up to 10,000 stored results belong in one field process.
Do not choose on this page alone if: minimum weight and pocket-size carry matter more than inspection.
Shortlist when: a dedicated meter, matching dual-wavelength sources, USB export, and more than 50 hours typical meter runtime fit the job.
Do not choose on this page alone if: Bluetooth, USB-C, or a broad selectable wavelength set is required.
Shortlist when: 1270 and 1577 nm settings matter and a supplier can provide the exact range, detector, accuracy conditions, calibration and warranty.
Do not treat as a winner yet: the public product page confirms wavelengths, not measurement performance.
These shortlist statements are inferences from public specifications, not hands-on rankings or purchase guarantees.

| Official field | EXFO Optical Power Expert PX1/PX1-PRO | VIAVI SmartClass Fiber OLP-82/82P | Fluke Networks SimpliFiber Pro |
|---|---|---|---|
| Wavelength coverage | 830–1625 nm or 780–1650 nm, detector/configuration dependent | 780–1650 nm | Official page lists calibrated wavelengths rather than one broad range |
| Calibrated wavelengths | 11 or 45, configuration dependent | 850, 980, 1300, 1310, 1490, 1550, 1625 nm | 850, 1300, 1310, 1490, 1550, 1625 nm |
| Power range | +10 to −70 dBm or +26 to −50 dBm, detector configuration dependent; the high-power upper value is marked typical | −45 to +10 dBm at 850 nm; −50 to +10 dBm at 1300/1310 nm; display range −65 to +10 dBm | +10 to −52 dBm at 850 nm; +10 to −60 dBm at the other calibrated wavelengths |
| Published uncertainty / accuracy | ±5% under the EXFO datasheet conditions | ±0.20 dB (±5%) under the VIAVI reference conditions | ±0.25 dB power measurement accuracy |
| Result storage | 1,000 test results | 10,000 measurement results | 1,000 results |
| Published battery runtime | 10 hours continuous use | 8 hours rechargeable Li-ion runtime | More than 50 hours typical |
| Data / connection | Bluetooth 5.0 BLE and USB-C | USB 2.0 | USB 2.0 full speed |
| Display | 2.8-inch color capacitive touchscreen | 3.5-inch color LCD with touch interface | Large LCD with four-button control panel |
| Inspection / automation | PX1-PRO adds VFL plus auto-wavelength recognition and switching with listed compatible EXFO sources; inspection scope is separate | Combines pass/fail inspection and OPM; OLP-82P adds an integrated dual-magnification patch-cord microscope | Auto-wavelength sensing with compatible Fluke sources; inspection and VFL are separate tools included only in selected kits |
| Size | 133 × 78 × 30 mm | OLP-82: 8.2 × 4.4 × 2.5 in; OLP-82P: 8.2 × 6.0 × 2.5 in | 16.5 × 8.0 × 3.9 cm |

PX1/PX1-PRO emphasizes portability and connected reporting. OLP-82/82P combines the largest stated local result store with an inspection-ready platform. SimpliFiber Pro publishes the longest typical meter runtime and works with a family of dedicated light sources. These are documented workflow differences, not proof of better repeatability, durability, service response, or total cost.
The accuracy row is not a winner calculation. EXFO, VIAVI and Fluke publish different terminology and reference conditions. A defensible performance ranking requires the same reference source, connector preparation, power levels, wavelengths, temperature, sample count and calibration traceability for every unit.
The manufacturer page lists nine selectable wavelengths: 850, 980, 1270, 1300, 1310, 1490, 1550, 1577 and 1625 nm. The 1270 and 1577 nm settings are relevant to newer access-network work, and a focused supplier relationship could make samples, customization and communication easier than buying through an unknown marketplace listing.
The tradeoff is evidence maturity. The public G11 page does not state measurement range, detector, uncertainty conditions, linearity, resolution, connector options, calibration interval, storage, runtime, reporting, warranty or environmental limits. That makes G11 a promising sourcing candidate, not a proven performance winner.

The EXFO PX1/PX1-PRO is the lightest of the three official specifications at 225 g including its battery.
The VIAVI OLP-82/82P datasheet states storage for up to 10,000 measurement results, compared with 1,000 for the EXFO and Fluke meters.
Fluke publishes more than 50 hours typical for the SimpliFiber Pro power meter. EXFO publishes 10 hours continuous use, while VIAVI states a minimum 8 hours with its rechargeable Li-ion battery.
The G11 manufacturer page lists nine selectable wavelengths, including 1270 and 1577 nm. It does not publish enough range, uncertainty, calibration, detector, runtime or warranty detail for a performance winner claim.
