Electrical interfaces
The iXblue Photonics modulator comes with three kinds of electrical ports:
1)
RF port: where the modulating signal is applied. Depending on the frequency range of
application, three kinds of RF/microwave connectors are used:
•
2.92 mm / K type, female, compatible to mate with SMA / 3.5 mm connectors.
•
2.4 mm, female, compatible to mate with V / 1.85 mm connectors.
•
1.85 mm / V type, female RF/microwave coaxial connector.
2)
DC port: where a DC bias is applied to set the operating point of the intensity modulator.
The DC connectors are gold plated pins (
0.76 mm).
3)
Internal photodiode (PD) port: only used with intensity or IQ modulators. The connectors
are gold plated pins (
0.76 mm).
