TF-1000: Tunable Optical Filter

The TF-1000 is a 50 GHz continuously tunable bandpass optical filter designed as a small, portable, cost-effective solution for use in R&D as well as production test applications. This band pass filter operates in either the C (1527 to 1570 nm) or L (1570 to 1610 nm) band and allows the center frequency to be set with a +/-4 GHz (32 pm) accuracy.

The TF-1000 can be USB powered when connected directly to a Windows based computer which runs the USB graphical user interface (GUI) software.  An AC/DC adapter is also provided to power the TF-1000 when its 10/100BaseT Ethernet interface is used to allow the module to be controlled via Static or Dynamic IP addressing. The TF-1000 has an embedded browser based GUI which provides all control and status capability over a standard Ethernet link.  SNMP control/status is also included when accessing the module with the Ethernet interface.

All three methods of access (USB, Ethernet browser, and SNMP) provide complete control and status of all wavelength tuning and optical power monitoring functions. The internal optical filter latches the wavelength setting and is able to maintain its filter characteristics at the last commanded location even when the TF-1000 is completely unpowered (no USB or DC power connection).

Feel free to download the TF-1000 Demonstration USB GUI which is a self-extracting installer .exe file that runs on any Windows XP, Vista, 7, or 8 platform. It demonstrates how the TF-1000 module can be controlled with a USB connection.
