External battery for optical power meter

External or rechargeable battery adapters can extend the operational time of optical power meters, making them ideal for field testing and remote fiber network measurements. Built-in vs External Power OptionsMany modern optical power meters, such as the Thorlabs PM60 and PM61 series, come with internal 2300 mAh LiPo rechargeable batteries capable of continuous operation throughout a workday. Some models, like the PM61 series, also support wireless inductive charging, providing additional flexibility in the lab or field.

These internal batteries are sufficient for most standard testing scenarios, but in remote or extended field operations, external battery solutions can be advantageous.

External Rechargeable Battery Adapters

For field technicians, rechargeable battery adapters are available to enhance portability and extend testing duration. For example, the SENTER ST805C PON Optical Power Meter Adapter features a built-in rechargeable battery that supports long-term FTTH network testing. It is compatible with SC/APC connectors and supports multi-wavelength testing (1310/1490/1550 nm), allowing accurate measurements across PON networks.

The adapter enables technicians to perform multiple tests without needing immediate access to mains power, improving efficiency in remote or hard-to-reach locations. Key Advantages: Extended battery life for prolonged field operations. Multi-wavelength support for testing across different fiber optic standards.

Portability for remote or outdoor testing environments. Compatibility with standard optical power meters via SC/APC adapters. Considerations When Choosing an External BatteryConnector Compatibility: Ensure the adapter matches the optical power meter's input (e.g., SC/APC, FC/PC).

Battery Capacity: Higher mAh ratings provide longer operational time. Rechargeability: Lithium-ion or LiPo batteries are preferred for reliability and longevity. Portability: Lightweight and compact designs are ideal for field use.

Multi-

Wavelength Support: Necessary for testing across different fiber optic networks.

Conclusion

If your optical power meter already has an internal rechargeable battery, it may suffice for standard lab or short field operations. However, for extended fieldwork, external rechargeable battery adapters like the SENTER ST805C provide reliable, long-lasting power, multi-wavelength support, and improved efficiency for fiber optic testing in remote locations.
