Abstract:
1. A two way optical cable communication system, comprising: a. a single optical communication cable connected between two optical transceivers, one at the proximal end and one at the distal end, operating at a constant wavelength for transmission of burst mode optical signals and receipt of burst mode optical signals with first bit of burst mode optical signal being valid data; b. said transceivers having a transmission section, a 45 degree partially reflecting mirror, a receiving photoelectric section perpendicular to the transmission direction and a ferrule for connection to said optical fiber; c. said burst mode optical signal transmitted from said transceiver passing through an optical isolator followed by said 45 degree partially reflecting mirror into said single optical fiber and any stray radiation from the 45 degree partially reflecting mirror being directed to a black body for the absorption of stray optical signals; d. said received burst mode optical signal from said optical fiber being reflected by said 45 degree partially reflecting mirror to a photoelectric detector and any stray optical radiation being blocked by said optical isolator; whereby reliable high-speed communication is established between two optical nodes from opposite sides of optical fiber optical signals traveling in opposite directions without optical signal alteration or the need for preamble pulses such as scrambling or encoding and delimiter stop bits.
