The Reliable Solution for Low-loss, High Bandwidth Applications


In data communications where high reliability, high data capacity, and ease of connectivity are required, OFS multimode optical fibers have become the medium of choice.  Among U.S. manufacturers, OFS offers the widest range of graded index multimode fibers as standard selections.
Consistent product quality, on-time delivery, responsive service, and excellent technical support are just a few of the reasons why OFS is one of the world’s leading producers of optical fiber.

OFS’ graded index multimode fibers are 100% quality tested in accordance with the Telecommunications Industry Association (TIA) Fiber Optic Test Procedures (FOTP) and other industry standards.

In addition, OFS optical fiber meets the optical and mechanical requirements of Telcordia Generic Requirements documents GR-20-CORE and GR-409-CORE.

Manufacturing and Quality Control
Robust and easy to connectorize, our Graded Index 62.5 µm Fiber promotes ease of installation even under the most stringent conditions.
OFS protects the fibers with our Flex-10 Coating, a dual-layered acrylate coating system that provides the industry’s best protection against water, temperature and humidity extremes, yet still strips cleanly and easily.

Like all of OFS’s graded index multimode fibers, OFS Graded Index 62.5 µm Fiber is tested and proven to exceed the Telecommunications Industry Association (TIA) Fiber Optic Test Procedures (FOTP) and other industry standards.
