  • Publication number: 20030179987
    Abstract: An optical communications control station includes an equipment rack and a fiber frame for interfacing between the fiber communications link and the equipment in the rack. Raman pump lasers in the equipment rack produce a Raman pump output that bypasses the fiber frame and is coupled directly into the fiber communications link. The number of connectorized components that the pump light passes through is reduced, thus reducing the possibility of damaging fiber connections by passing the high power Raman pump light through fiber connections. The approach also reduces the possibility of an operator being inadvertently exposed to the high power Raman pump light, thus increasing operator safety.
