Optical Multimeters
Handheld Optical Multimeter (OPM, VFL, OLS)
Overview: The Handheld Optical Multimeter is an essential 3-in-1 tool for fiber optic technicians, integrating an Optical Power Meter (OPM), a Visual Fault Locator (VFL), and an Optical Light Source (OLS) into a single, ruggedized device. This multifunctional fiber tester is engineered for installing, maintaining, and troubleshooting FTTx, LAN, and metro networks. As a direct manufacturer, we provide these high-precision optical test instruments at factory wholesale prices, ideal for B2B clients and bulk purchases.
Benefits & Applications
The primary benefit of an Optical Multimeter is efficiency, reducing the need to carry three separate devices and lowering costs. It is indispensable for field applications such as measuring optical power loss (dBm) in a network link, identifying fiber breakpoints, bends, or bad splices with the high-power VFL, and providing a stable light source for continuity testing. Common deployments include FTTH network activation, data center maintenance, and CATV system verification.

FAQ
1. What is a 3-in-1 Optical Multimeter?
A 3-in-1 Optical Multimeter is a versatile fiber optic test instrument that combines the functions of an Optical Power Meter (OPM) to measure signal strength, a Visual Fault Locator (VFL) to visually find fiber breaks, and an Optical Light Source (OLS) to send a stable signal for testing.
2. How does the Optical Power Meter (OPM) function work in this integrated device?
The Optical Power Meter (OPM) function in this integrated tester measures the absolute optical power (in dBm) or relative power loss (in dB) of a fiber optic link. It supports multiple calibrated wavelengths, such as 1310nm and 1550nm, to provide accurate readings for network diagnostics.
3. What is the maximum distance the Visual Fault Locator (VFL) in the optical tester can reach?
The maximum distance the Visual Fault Locator (VFL) can reach depends on the output power. Our optical tester models are available with VFL powers of 10mW, 20mW, or 30mW, capable of identifying breaks and microbends in a fiber cable from 10km up to 30km away.
4. Does this Fiber Optic Multimeter come with interchangeable connectors?
This Fiber Optic Multimeter comes standard with a 2.5mm universal adapter that is directly compatible with SC, ST, and FC connectors. Optional 1.25mm adapters for LC connectors are also available upon request for wholesale orders.
5. Is it possible to buy the Handheld Optical Multimeter in bulk directly from the factory?
Yes, you can buy the Handheld Optical Multimeter in bulk directly from our factory. We specialize in B2B sales and offer significant discounts and factory pricing for wholesale and high-volume orders.
6. How often should an Optical Power Meter be calibrated?
For optimal accuracy, it is recommended that an Optical Power Meter be professionally calibrated annually. However, our devices include a user self-calibration function that allows for minor adjustments in the field to maintain measurement precision between formal calibrations.
7. Can the VFL feature of the fiber optic tester find a break through a dark jacketed cable?
The VFL's bright red laser can effectively pinpoint breaks in the fiber core, which will show as a glowing point. While visibility through thick or dark-colored cable jackets can be limited, the VFL in our fiber optic tester is powerful enough to reveal faults in most patch cords and buffer tubes.
8. What wavelengths can the OPM component measure?
The OPM component of our optical multimeter is equipped with six standard calibrated wavelengths to cover all common network applications: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, and 1625nm.
9. Does your company offer OEM branding for these optical test kits?
Absolutely. As a direct manufacturer, we offer full OEM branding services for our optical test kits. We can customize the device casing, user interface, and packaging with your company logo and details for bulk orders.
10. What is the typical battery life of this multifunctional OPM/VFL device?
The multifunctional OPM/VFL device is equipped with a high-capacity rechargeable lithium battery that provides over 48 hours of continuous operation, making it highly reliable for long workdays in the field.
11. Can I get a wholesale price for the Optical Multimeter?
Yes, we provide competitive wholesale pricing for the Optical Multimeter. Please contact our sales team with your required quantity to receive a formal quotation for your business.
12. What is included in the package with the 3-in-1 Fiber Tester?
Each 3-in-1 Fiber Tester package typically includes the main unit, a protective carrying case, universal SC/FC/ST adapters, a charging cable/AC adapter, a user manual, and a calibration certificate.
13. Is the optical multimeter suitable for both single-mode and multi-mode fiber testing?
Yes, the optical multimeter is perfectly suitable for both single-mode (SM) and multi-mode (MM) fiber testing. Its wide range of calibrated wavelengths, including 850/1300nm for MM and 1310/1550nm for SM, ensures it can be used across different network types.
14. How does the self-calibration function on the Optical Power Meter work?
The self-calibration function allows the user to manually adjust the power meter's readings to match a known reference source. This feature on our Optical Power Meter helps maintain accuracy and compensates for minor deviations without needing to send the unit back to the factory.
15. Why should I purchase a combination OPM+VFL unit from a direct supplier?
Purchasing a combination OPM+VFL unit from a direct supplier like us ensures you receive the best possible factory price by eliminating distributor markups. It also provides better access to technical support, customization options (OEM), and warranty services.
