Feature

■Dimension

■High reliability by weld fixed fibers

The fibers are collimated, and fixed by welding.
The minimum gaps of optical axis ensures excellent reliability.

Application

■Research and development for the communication.
For test and selection of various filters.
For research and development of optical fiber communications.

■For wavelength selection in WDM system (Combined with a LED/ASE light source)
