About This Product

■Summary

・100KHz to 1,200MHz E/O converter ・Very small modulated light source. -Easily convert it into a light output device by simply attaching it to your sweep generator or function generator. The LL series is an E/O converter that generates an optical signal that is intensity-modulated using the input electrical signal. By attaching this device to the signal output terminal of a sweep generator or function generator and inputting the signal, modulated laser light will be output from the optical output connector of this device.

■Notice for use

-The optical output of the LL series when there is no modulation signal input is CW light of 0.25 [mW] or more at the fiber end when a 50/125 type GI fiber is installed. Therefore, you can use this device as a CW light source even when a modulated light source is not required. -Since this LL series uses a single mode semiconductor laser, return light noise may become a problem depending on the application. Only when using this unit as a CW light source, by inputting a high frequency signal from the modulation signal input terminal, it is possible to superimpose high frequencies on the laser light and reduce these noises.
