American Fibertek RR81 Eight Channel Contact Closure System, Multimode, Rack Card Receiver

  • Also known as: RR81, AZ-RR81, AFI-RR81

  • The American Fibertek RR81 operates as half of a transmitter/receiver pair for the transmission of eight dry latching contact closure signals. It is designed to operate with the MT-81 or RT-81 contact closure transmitter over one multimode fiber optic cable. The 81 series receiver has a user selectable switch that allows the contact status sent by the MT-81 or RT-81 to be maintained unchanged through loss of optical or electrical power at the receiver. Both the transmitter and receiver include a recessed button to clear all contacts to a default state.

    The RR81 converts an optical input into eight contact closure outputs using a 1310 nm wavelength detector. The 81 Series product is designed to operate over an optical loss budget range of 0 to 12 dB on 62.5 um fiber. The RT81 operates on 50 um or 62.5 um multimode fiber.

    This unit is designed for rack mounting in either of two American Fibertek subracks available. The subrack model numbers are SR-20/2 or SR-20D/2. Slide in rack mounting, detachable terminal blocks and LED indicators provide for easy installation and monitoring of data and optical power. The RR81 is designed for mounting as a rack mounted unit. For a modular stand alone version please see the MR-81.
