Claim:
1. A system for protecting against points of failure in a daisy-chain network, the daisy-chain network deployed along a linear facility between a proximal site and a distal site, the system comprising: a daisy-chain network comprising a plurality of communication nodes operably connected to one another in a daisy-chain linear topology via a fiber optic cable, the plurality of communication nodes including: a main site communication node being positioned at the proximal site, a remote site communication node being positioned at the distal site, one or more intermediary communication nodes being positioned in the daisy-chain network in a series between the main site communication node and the remote site communication node, the one or more intermediary communication nodes configured to relay a transmission between the main site communication node and the remote site communication node, an intermediary communication node of the one or more intermediary communication nodes positioned between a reference communication node and the remote site communication node being characterized as upstream from the reference communication node and an intermediary communication node of the one or more intermediary communication nodes positioned between the reference communication node and the main site communication node being characterized as downstream from the reference communication node, the one or more intermediary communication nodes including a bypass-capable communication node, the bypass-capable communication node including: communication node bypass circuitry configured to provide a bypass communication path around the bypass-capable communication node for the transmission segment between the adjacent downstream communication node and the adjacent upstream communication node; an optical switch configured to switch the bypass-capable communication node from the communication node primary circuitry to the communication node bypass circuitry; one or more processors; and tangible computer readable medium in communication with the one or more processors, the tangible computer readable medium having stored therein a plurality of operational modules, each of the operational modules comprising a set of instructions that when executed cause the one or more processors to perform operations, the plurality of operational modules including:
