Abstract: A partition feeder (10) has a multi-rack assembly for holding more than one reserve stack of partitions (14). The partition feeder ( 10 has a main stack of partitions which is forced against a set of tabs (18) an d which has its partitions (14) removed by a selecting a pparatus (32). When the main stack has been reduced down past a certain amount, one o f the reserve stacks is automatically moved into alignme nt with the main stack and the partitions (14) in the reserve stack are added t o the main stack. The partition feeder (10) has guide ra ils that are received in notched sides of the partitions, thereby suspending the part itions (14) on the guide rails (12). An inner frame (166 ) upon which the guide rails (12) are mounted, is adjustably mounted to a middle fr ame (164) to thereby permit the adjustment of the distan ce between the guide rails (12). The partition feeder can therefore be easily a djusted for partitions of different sizes.

Title: Thermal down-mixing in diode laser transmitters to suppress stimulated brillouin scattering
Inventor: GOODWIN JOHN CHARLES
IPC: H04B10/18
Filed: 1996-12-06
Granted: 2001-08-14
Abstract: A method and apparatus for transmitting an analog signal over an optical fib er cable is disclosed. A semiconductor laser provides an optical carrier signal , the laser having the natural linewidth at high power of the same order as th e SBS linewidth. The method comprises directly modulating the current of the laser with a dither signal comprising a first component fC and a second component fS. Due to the nonlinearity of the "I-V" characteristic of the laser, a thermal modulation component fT appears in the active region. This thermal modulation component reshapes the spectrum of the semiconductor lase r to increase the threshold of the SBS. As a result, the energy of the signal transmitted over the optical cable may be increased by approximately 16 dB. The first frequency is at least twice the maximum frequency of the analog signal and the second frequency is selected to obtain fC - fS = fT.
