An optical-transmission system includes a split-gain amplifier, a first connector device, a second connector device, and a signal-modifying device. The split-gain amplifier has a first gain stage optically connected to a first set of at least two waveguide paths and a second gain stage optically connected to a second set of at least two waveguide paths. The first connector device optically connects the at least two waveguide paths of the first set to a first combined-waveguide path. The second connector device optically connects the at least two waveguide paths of the second set to a second combined-waveguide path. The signal-modifying device is optically connected to the first and second combined-waveguide paths.

Optical-transmission system having a split-gain amplifier and a signal-modifying device

Apparatus for packaging a fiber optic device along with electronic and opto-electronic components upon a printed circuit board. Bend members having arcuate shaped guide surfaces for directing fibers between various components are strategically mounted upon the top surface of the board. Passive fiber optic components are also mounted upon support means between bend members so that the fibers entering and exiting the passive component run tangent to the bend radius of the bend members. The radius of curvature of the bend members is within the bend tolerance of the fibers used in the device. The bend members and support members are formed of a material having a thermal coefficient of expansion that is about equal to that of the board material whereby thermally induced stresses on the board mounted components are minimized.
