Paper Abstract

We describe a new ultra long distance DFB fiber laser hydrophone system by using only one Raman pump laser source with 1W output power at 1395nm and one section of erbium doped fiber. An all fiber backscattering suppression module and 1550nm bandpass filter are used to reduce external reflection to DFB laser and remove unwanted the remaining pump light in 1480nm band. A 50km DFB fiber laser hydrophone system has been successfully demonstrated to detect acoustic signals.
