FTTH Optical Receiver TERRA OD-004 R81730 is used in systems distributing SAT TV, DVB-T and FM/DAB signals via optical fibers. Fiber-optic systems are characterized by low loss and immunity to electromagnetic interference, so they can easily transmit signals over long distances.
The OD-004 R81730 optical receiver converts optical signal into RF spectrum. This modern small device is dedicated for end users in FTTH distribution networks. It can be fed from the mo418 4D31 R82522 TV optical transmitter via a single-mode link.
The high sensitivity of the device within -15...-6 dBm range and optional -8...0 dBm range allow for economical distribution of the optical signal. The maximum output level of 80 dBµV is suitable for providing RF signals to several outlets in an apartment, an office, or a single family home.

Key features
  • small size,
  • RF output range: 47-2400 MHz,
  • three AGC modes based on RF level support independently from optical level,
  • microprocessor controlled, with two-digit display,
  • optical connector: SC/APC; RF connector: F-type.
Customers can order any patch cords made to order with required terminating connectors. Please contact your sales assistant.
