3540A 5 GHz DFB Laser Transmitters
DATASHEET | NOVEMBER 2013
MICROWAVE
The 3540A Distributed Feedback (DFB) laser transmitters provide
exceptional performance for linear fiber optics communications
in very wide bandwidth applications. EMCORE’s linear fiber optics
are excellent alternative to using coaxial cable systems to transmit
10 MHz to 5 GHz signals. They offer significant improvements in
reliability in microwave communications networks by transmitting
the RF signal in its original format. As a result of these properties,
these microwave DFB laser transmitters provide significant improvements in signal quality for a wide variety of applications including antenna remoting, timing
and reference signal distribution, telemetry, measurement and delay lines.
Applications
„„ Antenna Remoting
„„ Cellular and PCS Networks
„„ Military Triband Communications
The 3540A is available as a flange-mount design for extreme environments or as
a plug-in for integration with EMCORE’s System 10000 rack-mountable chassis
and power supplies. Electronics within the flange-mount and plug-in transmitters
control the laser temperature and DC bias current and provide warnings whenever the temperature or power deviates from their intended levels, thus providing a self-regulating, fully-integrated microwave product. These units provide
high-quality noise performance in sensitive optical links.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings
only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
