Bend Insensitive Multimode Fibres OM4

Very low   macro-bending sensitivity

Low   micro-bending sensitivity

The fibre is easier to handle and install without excessive   care when storing the fibre, for example, in splicing cassettes

Supports   installation with small cable bend radii and compact organizers

Facilitates jumper moves,adds and changes

Maintaining compatibility with current

OM2+/OM3/OM4 multimode optical fibre

Low differential   mode delay (DMD)

Low attenuation
