SAMSUNG FIBEROPTICS
SAMSUNG 50/125 m multi-mode optical fiber is a graded index fiber with a 50 m core
and 125 m cladding diameter. It is suitable for fiber optic networks based on Ethernet,
Fibre Channel, FDDI, ATM, and Token Ring protocols. It offers superior performance and
reliability for backbone, riser, and horizontal applications in premise networks.

FEATURES / BENEFITS
Optimized for 850 nm and 1300 nm dual wavelength ranges
Coated with a high performance dual acrylate coating for long-term reliability
Excellent compatibility with any commercial fiber in legacy network systems
APPLICATIONS
Local Area Networks and campus networks with high data-rate voice, video and
data communication systems using LEDs, VCSEL or Fabry-Perot lasers
QUALITY TESTING
Every spool of fiber is tested to assure top quality and performance
All test procedures comply with ITU recommendations, IEC and EIA Standards
DESIGN
Core
Center of the optical fiber, which carries the light
Clad
Confines the light to the core, using total internal reflection principles
Coating A dual layer provides a microbend free environment, which also protects
the optical fiber from external influences and absorbs shear forces
