|Описание:||Optical Time-Domain Reflectometer|
The TEKTRONIX TFP2A FiberMaster Optical Time-Domain Reflectometer (OTDR) is an optical-fiber test instrument capable of measuring loss characteristics and displaying faults, splices, and other fiber events in singlemode and multimode optical fibers. FiberMaster applies pulses of light to the fiber under test via the optical output connector. As the pulses travel through the fiber, some light is reflected back to the instrument. These reflections are processed to display a visual representation of the fiber on FiberMaster’s cathode ray tube (CRT), where you can make distance and loss measurements on the fiber under test. The CRT display is a time plot, read from left to right. The trace starts with the outgoing pulse, and the time difference is converted to distance in the measurement process. When you view a typical fiber display, events that are further down the fiber appear to the right (later in time). Loss is measured on the CRT’s vertical scale. Modular, Plug-In Laser Sources ❏ The FiberMaster OTDR was designed using a modular approach that allows you to choose options that answer your specific test and measurement applications. You can upgrade your instrument configuration as your system requirements change. FiberMaster can accommodate 850-nanometer (nm) multimode, 1300- nm multimode, 1310-nm singlemode, and 1550-nm singlemode laser sources in one or two plug-in modules. The modules can contain either two singlemode or two multimode lasers, or any single laser, allowing the instrument to be configured with one to all four wavelengths. ❏ Temperature-controlled laser light sources ensure stable wavelength and optical output for highly accurate measurements. Accurate, High-Speed Data Acquisition and Measurement ❏ The internal 32-bit microprocessor performs up to 16 million high-speed averages per acquisition, maximizing the signal-to-noise ratio, giving a clear display of fiber events. ❏ FiberMaster measures a specific fiber feature, with single-keystroke convenience. In addition, manual adjustments provide extended flexibility in interpreting the fiber data. ❏ An expand function allows you to magnify any portion or feature on the displayed fiber acquisition. ❏ FiberMaster’s high-density acquisition capability offers extended expansion capacity and highly accurate measurements. ❏ A masking function can be performed automatically, or you can set manual masks to reduce dead zones caused by large Fresnel reflections, improving measurement resolution. Automatic and Manual Event Marking ❏ The instrument’s event-marking function automatically locates and measures events on the fiber under test that have splice losses above a user-specified threshold, or you can also mark events manually. ❏ An event table is compiled displaying the measurements for each marked event. You can edit and print out this table, plus enter notes and mapping information about each event. Extended Memory and Storage Capacity ❏ FiberMaster offers both a current memory, containing the current data acquisition, and a reference memory, for previously acquired fiber waveform data. A dual-trace mode makes it possible to display the contents of both current and reference memory simultaneously, allowing you to compare a current optical-fiber acquisition to historical data. ❏ Mass-storage devices (the standard floppy-disk drive and optional internal RAM) permit unlimited storage of waveform and settings data on both removable and internal media. Hardcopy Options ❏ You can choose the optional high-speed internal thermal printer, or use FiberMaster with either an IEEE 488 general-purpose interface bus (GPIB) external plotter or printer, or an RS232 external plotter or printer. One press of a button on the instrument’s front panel provides a 15-second hard copy of the displayed waveform and instrument settings on the internal printer. Remote Control Capability ❏ The FiberMaster OTDR can be operated under the remote control of an instrument controller or a computer with a GPIB interface, using an IEEE 488 general-purpose interface bus, or via the RS-232 serial interface. Additional Features ❏ An easy-to-use menu system simplifies setting instrument measurement parameters. ❏ You can upload and download waveform and settings data using the RS232 interface and XModem protocol. ❏ The 7-inch diagonal, high-resolution color or monochrome CRT provides a comprehensive on-screen readout of waveform and measurement data, and instrument settings. ❏ Online help displays context-sensitive operator assistance at the press of a button. ❏ Rugged, portable construction is also lightweight—under 35 pounds (15 kilograms).
