Singlemode Fibers
Singlemode Fibers
Singlemode Fibers (400 - 2000nm)
Singlemode fibers are primarily used for applications that require signals to be transmitted over long distances with minimum loss. They have a smaller core than multimode fibers so that the light is only able to propagate in one mode.
Our series of singlemode fibers are used across telecommunications, aerospace, and industrial markets in applications such as wavelength division multiplexing (WDM) couplers, splitters, and pump pigtails. The high-index fibers are manufactured with outside vapor deposition (OVD) process which results in highly consistent glass and excellent reliability.
