200ps or less (10%-90%) |
100kHz to 2GHz |
Approximately 800mVp-p is recommended (100mVp-p to 1Vp-p) |
SMA receptacle on front panel |
50Ω, 0[V] termination, AC coupling |
One channel is provided to output the input signal to the modulation input terminal as a monitor externally after waveform shaping. |
The light intensity increases when the voltage of the modulation input signal falls, and the light intensity decreases when the voltage rises. |
400mVp-p or more |
SMA receptacle on front panel |
50Ω, AC coupling |
Feedback control of laser drive current by monitor PD current monitoring with built-in laser element |
Direct modulation method using laser drive current modulation |
7dB or more (when modulating with 2.5Gbps PRBS) |
0dBm |
1 channel |
FC receptacle on front panel |
Double Peltier system that controls the temperature of the entire built-in laser module as well as feedback control using the thermistor and Peltier element built into the laser element. |
30℃ |
Opposite phase to modulated input signal |
3Gbps O/E Receiver Module |
