Furukawa Electric released in May 2008 a fusion splicer(Note 1)for large cladding diameter optical fibers(Note 2) up to 400 µm.

While optical fibers for telecommunications use are 125 µm in diameter, optical fibers having larger diameters (hereinafter called large diameter fibers) are increasing in demand for non-telecommunications applications such as the high-power and medical lasers, accompanied by a growing demand for fusion splicers for the large diameter fibers.

We have recently developed, based on the S177A optical fiber fusion splicer that has established a worldwide track record, a fusion splicer for large diameter fibers featuring ease of use due to its compact size and lightweight, as well as low price.

Product Features

  • Applicable fibers
    Applicable cladding diameters of optical fibers range from 125 μm for telecommunications applications to 400 μm. Splicing of different-diameter fibers between 125 μm and 400 μm is also possible.
  • Splicing time
    Splicing of 400 μm fiber is automatically completed in only 26 sec after fiber setting on the splicer.
  • Compact size and lightweight
    All the components and mechanisms needed for splicing of large diameter fibers are accommodated in the same body size as for the S177A optical fiber fusion splicer platform, thereby achieving compact size and lightweight. No extra space for equipment installation is needed.
  • Simple operation
    A graphic user interface (GUI) equivalent to those for standard fusion splicers has been equipped, realizing the same level of operability as for mobile phones thanks to its display using simple function keys and eye-friendly icons.
  • Standard price
    The standard price per basic set is 2,600 thousand yen.

Glossary

(Note 1) Fusion splicing:
A splicing technology in which optical fiber ends are fused together. Axial alignment of optical fibers comes generally in two types: active alignment in which optical fibers are placed on a pair of V grooves permitting relative displacements in the X- and Y-directions, and axial alignment is performed until the misalignment measurements reach within the specified limit; and passive alignment in which axial alignment is done by placing optical fibers to be spliced on a cut-through V groove. The S177LDF has adopted the active alignment enabling high-precision alignment.Back to Main Content

(Note 2) Large diameter fiber (LDF):
Optical fibers having a diameter larger than that of telecommunications optical fibers (i.e., 125 µm). The demand for LDFs is increasing in the fields of the medical and high-power lasers. While some of the larger fibers exceed 1,000 µm in diameter, the mainstream is constituted by around 400 µm.Back to Main Content
