Small Integrated Transmitter Unit
SITU2400
0.05 – 3 GHz, 1550nm Directly Modulated Self-Contained Transmitter
The Emcore Small Integrated Transmitter Unit (SITU2400) is a high-
performance, directly modulated transmitter for applications with
guaranteed performance over the 50 MHz to 3 GHz frequency band.
The SITU2400 is a fully integrated unit that contains both the optics and
the control electronics. Only DC input voltages and the RF input signal
are required for operation.
The unit can be used to construct transparent optical links for antenna
remoting, microwave delay lines and other applications where it is
necessary to transport RF over long distances without signal
degradation.
The unit operates at a nominal optical wavelength of 1550 nm and ITU
wavelengths are available for CWDM and DWDM applications.
