Buyer decision
A focused meter candidate whose exact measurement configuration still needs to be fixed in writing.
The practical advantage in the reviewed public page is the nine-wavelength selection, including newer access-network labels. That is a useful shortlist signal, not proof of accuracy, repeatability, detector performance, or live-network suitability.
Shortlist it when
The job is an out-of-service or single-signal optical power check, the published wavelength set matches the network, and the supplier can document the exact ordered configuration.
Compare an overseas reference when
You need a mature published range, uncertainty conditions, result storage, inspection workflow, reporting, or service documentation before approving a sample.
Do not choose from this page alone when
The job requires live-PON upstream and downstream separation, traceable calibration, a fixed accuracy limit, or independently measured repeatability.
What is publicly supported
- Brand and model
- GUANGYAN G11 optical power meter.
- Published role
- Dedicated optical power measurement.
- Selectable wavelengths
- 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, and 1625 nm.
- What the list does not prove
- It does not by itself establish measurement range, uncertainty, detector type, wavelength isolation, burst-mode capture, or through-mode operation on a live PON.
- Evidence still required
- Exact range and detector, accuracy conditions, calibration record, connector package, battery and runtime, environmental limits, warranty, and repair route.
Choose the comparison by the real job
G11 vs VIAVI OLP-87
Use this comparison when 1270 and 1577 nm matter and you need to distinguish a selectable wavelength setting from wavelength-selective through-mode measurement.

Use this comparison when documented range, accuracy, storage, reporting, inspection, battery life, and mature support are the main buying filters.
Compare established optical power metersG11 vs GUANGYAN Y9
Use this comparison to choose between a focused power meter and a configurable tool combining optical power measurement, VFL, and RJ45 cable testing.
Compare G11 and Y9 by workflowFour checks before a sample or order
- Put the exact detector, measurement range, connector, adapter package, and firmware or revision in the quotation.
- Request model-specific accuracy conditions and a serial-numbered calibration record with the relevant wavelengths and uncertainty.
- Define a repeatability check against a traceable reference across the power levels and wavelengths used in the real job.
- Confirm the battery test method, included accessories, warranty exclusions, repair destination, response time, and replacement route.

Frequently asked questions
Which wavelengths are published for the GUANGYAN G11 optical power meter?
The reviewed manufacturer page lists 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, and 1625 nm.
Can the G11 replace a wavelength-selective live-PON power meter?
Not on the public evidence reviewed. A selectable calibration wavelength does not prove simultaneous signal separation, through-mode operation, or burst-mode capture.
Has Fiber Tool Lab independently tested the G11?
No. This page does not publish an independent accuracy result, score, or performance winner.
