1. FiberPal™ OTDR


FiberPal is a compact, cost-effective portable Optical Time-domain Reflectometer (OTDR), designed for full-range fiber fault detection. It delivers the same features as desktop model. Designed specifically with fieldwork in mind it is ideal for optical fiber installation/maintenance, field construction, and other in-site fault-locations analysis. Its outputs are formatted to ease planning and documentation efforts and to minimize time spent on-site.

The FiberPal encompasses two parts: a plug-in module (MMO) which perform all OTDR functions, and a Mainframe Interface (MFI) console which provides power, data interfaces, and LCD display, a touch-screen input, and a thermal printer.

On the MMO, a short laser pulse is injected to the fiber under test and an avalanche photodiode (APD) picks up any scattered and reflected optical signals. This process is repeated again and again and an integration process is also invoked to suppress the noise. The MFI Console (MFI-001) is a miniature 80486-based computer that is powered by 4 Rechargeable Li batteries or AC. The application (AP) execution sequence is done automatically using the touch-screen commands, and the digitized waveform is displayed in 3 seconds.

The AP consists of two windows. The Event Handling window (default) allows for parameter setting, measurement data storage and event analysis processing. The Event Mapping window provides mapping of a measured trace to a predefined landmark table, and subsequently the actual fault location, instead of pure distance, can be shown.
