RFOptic’s programmable low frequency (up to 6GHz) direct modulation RFoF solutions cover bandwidths from 0.5MHz up to 2.5GHz, 3GHz, 4GHz, or 6GHz. Enclosures containing sets of modules can be monitored & controlled remotely via USB or HTML/SNMP/REST interfaces.

These solutions are especially suitable for phase-matched link sets, EW applications, and remote antenna applications.

Key Features

  • RF bandwidth 5MHz up to 6GHz.
  • Excellent linearity, gain flatness, gain control in both Tx, Rx and Link terminals.
  • Noise Figure as low as 6 dB with LNA On, yielding an MDS of ~168 dB/Hz for very low incoming RF signals.
  • Microcontroller controlled RF and Optical configuration, enabled by software.
  • In module and end-to-end diagnostics reduces installation and maintenance time, enabled by software.
  • Gain variation S21 of ±1dB for 90°C range, utilizing special algorithms.
  • Remote management by GUI installed on PC.


  • Single unidirectional or bidirectional RFoF link
  • Multiple RFoF links in an outdoor enclosure (unidirectional/bi-directional)
  • Multiple RFoF links in 1U 19” rack mount enclosure (4/8 terminals)
  • (1U,2U,3U) 19” rack mount Removable panel enclosure with capacities of (4/8/12) terminals respectively.
