Data Sheet June 2001 Wideband DFB Laser Transmitters Description Features High dynamic range Long distance communication 10 MHz to 18 GHz bandwidth Built-in optical isolator, 1310 nm or 1550 nm Y2K compliant, CE certified Applications Antenna remoting Cellular and PCS networks Military triband communications TT and C The distributed feedback (DFB) laser transmitters provide exceptional performance for linear fiber-optic communications in very wide bandwidth applications. Linear fiber optics developed by Agere Systems Inc. are an excellent alternative to using coaxial cable systems to transmit 10 MHz--18 GHz signals. They offer significant improvements in reliability in wideband communication networks by transmitting the RF signal in its original format. As a result of these properties, these wideband 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. Wideband DFB lasers are available in several packaging styles. The basic laser module can be integrated into a complete transmitter, packaged either as a flange-mount for extreme environments or as a plug-in for integration with Agere Systems' System 10000 rack-mountable chassis and power supplies. Electronics within 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 wideband product. These units provide high-quality noise performance in sensitive optical links. Data Sheet June 2001 Wideband DFB Laser Transmitters 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.
