* High wavelength accuracy Features ±0.02 nm wavelength accuracy at 1520 to 1580 nm and ±0.05 nm accuracy at 1580 to 1620 nm, using an internal light source to perform wavelength calibration.
Internal wavelength calibration function The built-in reference light source eliminates the need for an optical fiber connection to an external light source to perform wavelength calibration. Connection to the reference light source is done automatically by an internal optical switch.
High dynamic range and high wavelength resolution With dynamic range of 55 dB or more (peak ±0.4 nm) and wavelength resolution of 0.05 nm (min.), 50 GHz channel-spaced DWDM systems can be measured.
High power measurement Optical amplifier output and high output laser diodes in DWDM systems can be measured directly because the measurement level can range up to +20 dBm.
Low polarization dependency Optical amplifier gain can be measured accurately because polarization dependency is as low as ±0.05 dB.
Long-term analysis function Changes to each DWDM channel peak can be measured over time.
Convenient programming function Shortens measurement time because measurement conditions and processes, etc., can be input to memory prior to measurement.
Individual traces of three wave-forms Individual traces of three waveforms can be displayed. Can also compare two waveforms - a reference waveform and a measurement result - to determine the difference between the each.
