LOW-LOSS, LOW-LATENCY, HOLLOW CORE FIBER COMMUNICATION SYSTEM

摘要

An optical fiber communication system includes hollow core fiber coupled between a transmitter device and a receiver device. Both hollow core fiber and solid core fiber may be optically coupled between the transmitter and receiver devices, with the hollow core fiber preceding the solid core fiber. A Raman pump laser may be coupled to the solid core fiber to provide distributed Raman amplification in the solid core fiber. A plurality of series connected spans of hollow and solid core fiber may be employed. First and second transmission lines each having a hollow core fiber may be provided in a single cable.
