Technical Specifications
Fabry-Perot source module specifications
(high-power modules, 13 dBm)
Specifications apply to the end of a 2 m long fiber cable (as specified under fiber
type) with Diamond® HMS-10/Agilent connectors attached. All specifications
are valid for an attenuation setting of 0.0 dB. All modules require straight output
connectors.
