Overview Specifications Related Products Order Now!
SIMTRUM provides a high-gain RF optical module product that is a high-performance, low-cost broadband optical transceiver. It is specially designed for light-carrying RF applications with a very wide dynamic range, providing high spurious-free dynamic range (SFDR) and operating frequencies from 500 kHz to 4.2 GHz. The product operates at 1.3 or 1.5 μm and comes with an average automatic power control function for the best stability of optical power over the entire operating temperature range.

 

Features

  • Compact design for assembly in standard chassis of 2U or more
  • Bandwidth up to 4 GHz
  • Gain up to 55 dB
  • High Spurious-Free Dynamic Range (SFDR)
  • Good Frequency Response
  • Adjustable bidirectional gain
  • Built-in MCU for monitoring the status of the 485 optical module

 

Applications

  • Multipoint RF Unlimited Distribution
  • WiMAX/ 4G LTE
  • GPS Distribution
  • Satellite Earth Station
  • Shipboard RF Distribution
