Abstract
Disclosed is a redundant TTE optical transmission system architecture which eliminates system signal power loss due to protection elements and thus provides a system power budget comparable to non-redundant TTE systems. Further disclosed is a virtually non-failing optical amplifier, for redundant and non-redundant optical systems, which allows for the simultaneous exploitation of the pump power from both sets of laser pumps in a dual-pump configuration, thereby increasing the available system power margin.
