Optimization of Fusion Splice Process for High Numerical Aperture Coupler Fiber and Erbium Doped Fiber
|
From OFS Specialty Photonics Division
Fusion splicing erbium doped fiber (EDF) to other single mode fibers has become more critical as the required overall insertion loss for erbium doped fiber amplifiers (EDFA) has significantly decreased in the last few years. In this paper, we describe and discuss an approach to developing a low loss splice method for fusion splicing high numerical aperture (NA) 980/1600 wavelength-division-multiplexing (WDM) coupler fiber and EDF. The results indicate that the fiber end preparation before the fusion is especially critical for obtaining a low loss splice for the fiber pair. Keywords: High NA 980/1600 WDM coupler fiber, EDF, Fusion Splice Loss In a typical erbium doped fiber amplifier (EDFA), a wavelength-division-multiplexing (WDM) fiber coupler is used as an energy and signal combiner to transmit the signal energy and deliver the optical energy from a laser diode (LD) to the erbium doped fiber (EDF), as shown in Figure 1.
