1540 FOE

Fiber Optic Expander

Gauging Systems Inc. designed a Fiber Optic Expander to be used in conjunction with Serial RS 232, RS 485, or Fiber to Fiber devices.

The Fiber Optic Expander allows one RS 232 (RS 485) or Fiber Input to broadcast to Four Fiber Outputs. The Expander boards are stackable through on board connectors allowing a single Input to broadcast to 4, 8, 12, or 16 Outputs.

The Fiber Optic Expander allows for the running of Fiber Optic Cable in a star topology from the Expander. Communications to the Fiber Optic Expander can be hard wired, fiber, radio, modem, etc.

Function: Provide up to four (4) fiber optic signal channels from a single fiber optic pair expandable in groups of four (4).

Operation: The Fiber Optic Expander (FOE) is based upon an electronic circuit that converts the light signals from the upstream side, to electrical and back to light to go to the downstream side. The circuit is constructed in modular form to allow the number of downstream ports to be increased by multiples of four (4). The circuits connect electrically to add fiber optic downstream ports, and there is no limit to the number of downstream ports, other than the physical size of the assembly.

Because the FOE is an active device, there is no loss of light signal, thus it is not necessary to consider the optical power budget.

The FOE enables the user to connect multiple fiber optic devices onto a fiber bus without the expensive and complex multiple fiber splices and splitters
