For Fast, Accurate Optical Power MeasurementLAFAYETTE, Colo., Nov. 18 -- dBm Optics Inc., a maker of DWDM (dense wavelength division multiplexing) optical test equipment for communications systems, has released its Model 4100 optical power meter, offering 100,000 readings per second, NIST traceability and a dynamic range of greater than 100 dB. The Model 4100 also has a USB flash memory drive and large color touch-screen display.
According to the company, the 4100 combines 100,000 r/s optical power meter modules with a powerful processor that can handle this exceptional measurement speed. When operated with two channels, each channel still measures at 100,000 r/s.
The 4100 captures an extended range of signal levels at a single sensitivity setting, enabling wide dynamic range within a single optical sweep. The 4100 has a dynamic range of >65 dB at full speed, eliminating the delay that similar meters suffer from in range transitions required by lower instantaneous range, according to dBm Optics.
When used with the Model 202 optical power meters, the polarization dependency of the power measurements is less than 0.0015 dB, reducing a significant source of measurement inaccuracy. The 4100 provides repeatability of ±0.005 dB for most typical connector insertion variations, including +-1 mm ranges in the x and y dimensions and a –1 mm to +3 mm in the z dimension.
The 4 x 6-in. VGA color display provides visualization of measurements directly on the power meter without the need to export data to a PC. Trends, drifts, noise and perturbations are all clearly indicated on the graphical display.
dBm Optics says the removable USB flash memory drive makes it easy to transfer data to Excel or a mathematics package. Remote data transfer via Ethernet or GPIB can be done by connecting to a network and retrieving data from any PC on the network (even to a remote location via VPN).
