At its most basic, an optical fiber is a glass thread, which can transmit messages modulated onto light waves. There are 2 main types of optical fibers, single-mode (SM) fiber, which has only one path, through a much smaller core, and multimode fiber, which has a large core and allows for multiple paths through the fiber.
Single-Mode Optical Fiber
The Fiber is the Network™
OFS is a world-leader in the design and manufacture of single-mode optical fiber for applications including transcontinental, regional, metropolitan, home/business access, and in-building fiber optic systems.
The OFS Single-mode Optical Fiber Selection Guide for terrestrial applications is a quick reference guide for a general understanding of OFS single-mode fiber types and applications. This guide describes several families of OFS fiber and provides recommendations for single-mode fibers used in Outside Plant (OSP) as well as Indoor (Premises, Enterprise) applications.
Selecting the right fiber for your application can help lower system costs. Characteristics such as lower loss, larger effective area, optimized dispersion, and tight bend performance can provide economic benefits compared to using a standard G.652D single-mode fiber. Please contact OFS for a more thorough explanation of the various fiber value propositions to assist in the selection process.
The OFS single-mode product portfolio single-mode product portfolio includes the following families of optical fiber:
- TeraWave® – ITU-T G.654 long haul fiber with an optimized large effective area designed especially to support coherent systems.
- TrueWave® – ITU-T G.655 and/or G.656 Non-Zero Dispersion fibers (NZDF) that have optimum chromatic dispersion characteristics to simplify and reduce the cost of dispersion compensation.
- AllWave® – ITU-T G.652.D standard single-mode fibers. AllWave Zero Water Peak (ZWP) Fibers provide seamless splicing and can be used everywhere from long haul to shorter reach in-building applications. Some of these fibers are also G.657 compliant.
- AllWave FLEX and EZ-Bend® are ITU-T G.657 Bend Insensitive single-mode fibers.
- TeraWave line of ocean fibers.
Multimode Optical Fiber
OFS is also a world-leader in the design and manufacture of multimode optical fibers. Our product portfolio offers high bandwidth OM3, OM4, and OM5 graded-index multimode optical fibers designed to support a wide range of short-reach, VCSEL based LAN, Central Office, and Data Center applications. Our LaserWave® laser-optimized multimode fibers cost-effectively support enterprise network speeds up to 400Gb/s and beyond. LaserWave WideBand (OM5) fiber supports the latest short wavelength division multiplexing (SWDM) applications developed to maximize multimode fiber’s data carrying capacity. DMD-controlled to provide optimum performance with laser sources, LaserWave optical fiber is designed and manufactured with a carefully controlled refractive index profile to achieve low attenuation, high bandwidth and longer link distances. The superior geometry of OFS multimode fiber results in easier cabling and better connector and transceiver coupling performance. Please contact OFS for a more thorough explanation of the various fiber types and to assist in the selection process.
OFS, through its predecessor companies, has been designing and manufacturing specialty fibers since the mid 1970’s and today offers a broad range of standard and custom versions. The specialty product range includes multimode (MM) and single-mode (SM) with a variety of core and cladding sizes, operating wavelengths, numerical apertures (NA), and coatings. These features optimize fiber performance in a specific application and are often designed in response to a customer’s application.
Our HCS®, HCXtreme®, GiHCS®, and LineaSens® PYROCOAT® brand optical fiber technologies are well known across industries. Our specialty single-mode fibers include polarization maintaining, erbium-doped , cladding-pumped, and Large Mode Area doped with various rare earth elements such as Erbium, Ytterbium, and Erbium/Ytterbium. OFS is an industry leader in optical fiber design or modification for a variety of industries including medical, industrial communications, avionics, and defense as well as for various sensing applications.
