An optical time domain reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network.

General Features of the OTDR DL110:

• Type: Handheld or portable OTDR

• Primary Function: Measures the length, attenuation, and faults (such as breaks or splices) in fiber optic cables.

• Wavelengths: Common test wavelengths include 1310 nm and 1550 nm (single-mode).

• Dynamic Range: Often between 26 dB to 40 dB depending on the model.

• Event Dead Zone: Typically low (e.g., ≤1m), allowing for accurate detection of closely spaced events.

• VFL Function: Many models include a Visual Fault Locator.

• Data Storage: Internal memory and support for USB export.

• Display: Color touchscreen or LCD for viewing fiber traces.

• Power: Rechargeable lithium battery for field use.

Typical Use Cases:

• Installation verification of new fiber links.

• Routine maintenance for service providers.

• Troubleshooting signal loss or breaks in FTTx, LAN, and backbone networks.
