50/125 µm Multimode Fiber
FEATURES
Original standard graded index Multimode fiber user usable at both 850nm and 1300nm wavelengths.
Dual mechanically strippable acrylate coatings are appliances on glass to provide excellent protection in different
environmental conditions.
Excellent dimensional control for low splice loss.
APPLICATIONS
Suitable media for short distance transmission, such as local area network (Ethernet, ATM and Fibre Channel),
CCTV system, where fiber attenuation and bandwidth requirements are modest.
