Appl. No.:

10/845633

Inventors:

Michael P. Duncan - Pulaski VA, US
Kanwai P. Lo - Blacksburg VA, US
Larry D. Vaught - Pembroke VA, US
Barry K. Witherspoon - Blacksburg VA, US

Assignee:

Moog Inc. - East Aurora NY

International Classification:

G02B 6/26
G02B 6/36

US Classification:

385 31, 385 49, 385 88

Abstract:

A fiber optic transceiver () is adapted for use in transmitting and receiving optical signals in a fiber-optic network (). The improved transceiver comprising: a multi-mode optical fiber () having a longitudinal axis (x—x) and having a proximal end (). The fiber is adapted to convey optical signals in either direction therealong. A photodetector () is arranged in longitudinally-spaced relation to the fiber proximal end. The photodetector has a sensitive surface () operatively arranged to receive light energy exiting the fiber through the proximal end. A light source () is arranged between the fiber proximal end and the photodetector surface. The light source is arranged to selective emit light energy into the fiber through the proximal end.

Assignee:

Litton Systems, Inc. - Woodland Hills CA

International Classification:

H04B 1000

US Classification:

359152

Abstract:

A hybrid fiber optic transceiver is described which includes a transmitter for converting electrical data signals to corresponding light energy, a receiver for converting optical data signals back to electrical data signals and a clock recovery mechanism to maintain the electrical data signals outputs from the receiver in their proper order. The transceiver includes an optical splitter or coupler that allows light signals to be transmitted and received over a single fiber. The opto-electrical hybrid circuitry of the transceiver and the fiber optic coupler are enclosed in a small light weight package which is hermetically sealed.
