Space division multiplexing (SDM) technologies are promising to respond to the demands of the increasing transmission capacity. Multicore fiber (MCF) is the one of the major candidate for fibers for future systems. In order to put MCF into practical use, many technologies such as cabling, connectors, fan-out devices are necessity. After installing MCF into field, adoption of SDM amplifier is also important to suppress the increase of power consumption. In this manuscript, several technologies enabling MCF installing in the real systems are summarized.
We review recent progress of multi-core erbium-doped fiber amplifiers (MC-EDFA). We confirmed by demonstrating a core-pumped MC-EDFA that MC-EDFs have practical amplification characteristics and core-to-core crosstalk. Three types of cladding-pumped MC-EDFAs are also reviewed, one uses free space optics, other uses a fiber bundled fan-in, and the other uses a side-coupled pump combiner for cladding pumping. Finally, we demonstrate a desktop-type prototype of a cladding-pumped MC-EDFA using the pump combiner that consumes power of 33 W and has size of 430×430×99 mm3 (width×depth×height).
HAFs and HFs (MOFs) having unique dispersion properties in near infrared and visible regime will be discussed. In
particular, we focus on the dispersion control in a 1.0μm band which have gathered rapidly increasing interests for the
aspects of both telecom and non-telecom applications. Furthermore, dispersion shift towards visible wavelengths using a
holey fiber technology has tried and the results will be explained. Finally, we will briefly discuss about the potential
usage of the MOFs for short wavelength transmission.
Recently, smaller diameter fibers have been investigated for flexible wiring and compact packaging. This paper summarizes the attributes of smaller diameter fibers. Applications of these fibers are also introduced in this report.
