Abstract
An electro-optical converter has at least three optical or electrical ports at least one of which is optical and one of which is electrical. The converter includes an essentially rigid support, a fiber-optic lateral coupler secured to the support including at least two length-wise continuous optical fibers juxtaposed along a portion of their length to provide lateral transfer of optical energy therebetween, and an electro-optical device also secured to the support in close relationship to the coupler. The device has at least one optical port and at least one electrical port. One of the coupler fibers communicates within the converter with the optical port of the electro-optical device, to serve as an internal signal link therebetween. The length of the link between coupler and electro-optical device is of the order of 10 centimeters or less. Protective means associated with the optical fibers, the electro-optical device and the internal link serve to protect the components from outside physical disturbance.
