SITU Series Unamplified Transmitters

EMCORE’s SITU (Small Integrated Transmitter Unit) series are high-performance externally-modulated transmitters for applications from 10 MHz to 40 GHz. Multiple RF operating bandwidths are available with two optical output powers of +7 dBm or +10 dBm available for each operating band.

SITU family transmitters are fully-integrated units that contains both the optics and the control electronics. Only DC input voltages and the RF signal are required for operation. The system operates at a nominal optical wavelength of 1550 nm. Wavelength selected lasers on the ITU grid are also available for WDM applications.
