Technical Specifications
Fabry-Perot source module specifications
(standard modules, 0 dBm)
Speciï¬cations apply to the end of a 2-m long ï¬ber cable (as speciï¬ed under ï¬ber
type) with Diamond® HMS-10/Agilent connectors attached. All speciï¬cations
are valid for an attenuation setting of 0.0 dB. All modules require straight output
connectors.

270 Hz, 330 Hz, 1 kHz, 2 kHz
and free selection 200 Hz to 10 kHz.
All output signals are pulse shaped,
duty cycle 50%.
Internal coherence control for line-
width broadening.
Output attenuation
The output power of all source mod-
ules can be attenuated from 0 dB to
6 dB in steps of 0.1 dB.
