FAULT TOLERANT, SELF HEALING COMMUNICATION
Phoenix Digital’s Fault Tolerant, Self-Healing Communication technology provides diagnostic moni-
toring of the communication signal waveforms at each node on the network, and ultra-high speed
detection, isolation, and correction of points of communication failure anywhere on the network grid.
Phoenix Digital’s fiber optic modules will self heal around communication failures in ring, bus, star,
tree, or point-to-point network configurations. Figure 1 illustrates Examples of Typical Fiber Optic
Module Network Configurations.
