2406LR

L-Band/Wideband Standalone Fiber Receiver Series

Interact with this product in a Layout Tool:

The 2406LR is a fiber optic receiver for signals in the satellite L-Band and other frequency ranges. It accepts a single fiber optic input on an FC/APC connector and provides a pair of equal power electrical outputs. Packaged in a small, standalone enclosure, the 2406LR is temperature-hardened and ideal for mounting on or near antenna structures, or in any application where modular/rack-mount products are not practical. The -WP version features dust and water protection for direct outdoor mounting without a secondary enclosure. When combined with the 2408LT a bi-directional link can be created, ideal for VSAT and similar applications.

Two gain modes are provided for flexible output level adjustment to suit the requirements of the coaxial distribution system and the connected equipment. Manual gain mode allows a fixed gain level to be applied to the output signal. AGC mode allows the user to set a target output level, and the 2406LR's microprocessor will automatically apply the correct amount of gain to maintain that level. Comprehensive local LED indicators provide instant information relating to optical input, DC power input and RF output levels.

For GPS applications, the 2406LR can be used to receive GPS signals over fiber when paired with a 2408LTA13-5V transmitter.

Features

  • Mounts directly to the antenna structure or other outdoor locations
  • -WP option provides a weatherproof version of the product
  • Wide bandwidth allows use with L-Band, over-the-air DTV and other frequency ranges
  • Protocol independent design - passes all modulation formats
  • Dual, full power outputs
  • Tri-color LED status indicators for optical input, DC input and RF output levels
  • Flexible powering options including power brick (+PS option), 2400PSUA-8 or customer's own 11 – 20V DC source
  • Fiber link provides electrical isolation between antenna and facility, mitigating ground loop and lightning issues
  • Fiber transport offers increased signal quality over coax at longer distances and is not prone to high-frequency roll-off

  • Applications

  • L-Band over Fiber Transport to L-Band up-converter for uplinks
  • VSAT and other bi-directional signals
  • Portable antenna deployment
  • Any RF fiber receive application requiring a standalone device
  • GPS antenna systems
