Wide Dynamic Range Optical loss of up to 120 dB can be measured using the high output (+10 dBm) light sources and the high sensitivity (-110 dBm min.) sensors.
High Output, High Stability DFB-LD Light Sources The DFB-LD light sources have a high output of +10 dBm while achieving a stability of better than < ±0.005 dB and a centre optical frequency stability of better than < ± 2 GHz, facilitating high-stability and high reliability measurement.
Conforms to ITU-T Wavelength Grid A complete line up of DFB-LD light sources for optical frequencies meeting the ITU-T recommendations for Dense WDM (DWDM) networks (191.7 to 195.9 THz at 100 GHz interval) is available.
High Accuracy Optical Power Measurement Under reference conditions, the optical power measurement uncertainty is < ±2%, and under actual operating conditions, it is < ±3.5% with a linearity of better than < ±0.01 dB. These excellent specifications permit measurement of optical power with high accuracy and repeatability.
Sensors with High Return Loss and Low Polarisation Dependency Even without a reflection / suppression adapter, the sensor return loss and polarisation dependency are 40 dB min., and 0.02 dB max. respectively, making them ideal for evaluating devices and systems that use optical amplifier.
High Speed Analog Output The optical sensors have a maximum bandwidth of 100 kHz (approx. 3 dB), permitting measurement of optical power variations with a response speed of approx. 10 ms.

GPIB and RS-232C I/F Since GPIB and RS-232C interfaces are standard, measurement can be controlled from a remote PC. In addition, the LabVIEW ® software driver bundle makes it easy to configure a remote measurement system.
Variable Optical Power Measurement Interval and Bandwidth The centre optical frequency of the DFB-LDs can be varied in a range of < 60 GHz (approx. < 0.5 nm). Moreover, it can be displayed in frequency and wavelength units [lambda (m) = c (m/s)/f (Hz), where c is the velocity of light in a vacuum (2.99792 x 108 m/s)].
