Abstract: An optical fiber security system is described. The optical fiber security system includes an optical fiber, an optoelectronic modulator and an optoelectronic demodulator. The optoelectronic modulator and the optoelectronic demodulator are both directly connected to the optical fiber. The optoelectronic modulator converts video signals to cable television video signals and subsequently converts to optical signals. The optical signals are transmitted to the optoelectronic demodulator through the optical fiber. The optoelectronic demodulator further reverses the optical signals back to the video signals to remotely monitor the environment.

Abstract: A pluggable optical transceiver module set includes an optical signal male connector with an elastic flake with an opening thereon, and an optical signal female connector with a bump, a holding rod and a driven element. When the optical signal male connector is plugged into the optical signal female connector, the bump is fastened in the opening, and the optical signal male connector is disconnected from the optical signal female connector when the holding rod is moved to rotate the driven element to press the elastic flake and release the bump from the opening.

Abstract: A Cable Television optical fiber communication system is disclosed, comprises a provider end, plural optical signal transmission devices and plural user ends, each optical signal transmission device is provided between the provider end and the user ends and has an light splitting element, a RF receive module, and a RF return module. The light splitting element is connected to the provider end via an optical transmission wire and is served to bi-directionally transfer a laser beam having a signal between the provider end and the user ends. The RF receive module is served to transfer a first signal of the provider end to the user ends. The RF return module emits a laser beam having a second signal to the provider end only when an analog return signal is emitted from the user end.
