American Fibertek RR-89A-L Single Fiber Bi-directional Transceiver, Rack Card Receiver, Multimode

The American Fibertek RR-89A-L operates as half of a transceiver pair for the transmission of bi-directional Aiphone LEF series intercom signals. It is designed to operate with the MT-89A-L or RT-89A-L audio transceiver over a single multimode fiber optic cable. In addition, the RR-89A-L can transmit one independent dry contact closure to the MT-89A-L or RT-89A-L.

The RR-89A-L converts an audio input signal along with a contact closure input into an optical output using an 850nm wavelength source. The RR-89A-L also converts an optical input signal returning on the same fiber into an audio output and a call button output using a 1300nm wavelength detector. The 89A-L Series product is designed to operate over an optical loss budget range of 0dB to 12dB. The RR-89A-L operates on 50um or 62.5um multimode fiber. Refer to the data sheets for detailed performance specifications.
