Optiva OTS-2 Series Microwave Band Fiber Optic Links Microwave Transport
Highlights
The OTS-2 Series Unamplified or Amplified (Tx, Rx Fixed Gain)
Microwave Band Fiber Optic Links are a family of SNMP man- n Low RIN source laser
aged fiber optic transmitters and receivers that provide high- n High-dynamic-range of
performance 50 MHz – 40 GHz transport within the Optiva >110 dB-Hz 2/3
modular platform. 18, 22 and 40 GHz options are available.
n Microprocessor-based transmitter
control for laser bias, modulator
Optiva microwave units are tailored to the requirements of bias and link gain
higher frequency applications such as microwave antenna signal
distribution, electronic warfare systems, broadband delay lines, n DWDM cooled DFB laser, 10 dBm
signal processing, and phased array antennas. Utilizing EM- output
CORE’s high-performance, ultra-low Relative Intensity Noise (RIN) source laser and high optical n SNMP and RS-232 monitoring and
input power capable photodiodes, these modules provide high-dynamic-range. The system oper- control
ates at a nominal wavelength of 1550 nm. Wavelength selected lasers on the ITU grid are also
available to support multichannel DWDM applications.
