| Multimode Optical Fiber |
|
Multimode fibers are graded index multimode optical fibers
which have core diameter of 50 and 62,5m,
These fibers have the highest bandwidth and lowest attenuation, which
is optimized for 850nm and 1300nm operation wavelength region.
For excellent optical and mechanical performances all materials are
specifically engineered to meet all industry specifications.
|
