Page 3: Functional Description
The RT-913 multiplexes a single video input signal along with up to three data signals into a high speed serial data stream. This serial data stream modulates a laser at 1310 nm wavelength. The RT-913 also detects and demultiplexes a return optical serial data stream signal containing up to three data channels at 1550 nm wavelength. -
