MICROWAVE
The 1742 18 GHz 1550 nm Microwave Distributed Feedback (DFB)
Laser provides exceptional performance for linear fiber optics
communications in very wide bandwidth applications. EMCORE’s
linear fiber optics are an excellent alternative to using coaxial cable
systems to transmit 10 MHz to 18 GHz signals. They offer significant
improvements in reliability of microwave communications networks
by transmitting the RF signal in its original format. As a result of
Applications
these properties, the 1742 provides significant improvements in signal quality for
a wide variety of applications including antenna remoting, telemetry, timing and
reference signal distribution, measurement and delay lines.
Antenna Remoting
Cellular and PCS Networks
Military Communications
Tracking, Telemetry, and Control
The basic 1742 laser module can be integrated into a complete transmitter either
as a flange-mount for extreme environments, or as a plug-in for EMCORE’s Sys-
tem 10000 rack-mount system. Electronics within the flange-mount and plug-in
transmitters control the laser temperature and DC bias current and provide warn-
ings whenever the temperature or power deviates from their intended levels.
This provides a self-regulating, fully-integrated microwave product with excellent
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.
