MaxCap-BB-OM3 / OM4Draka’s Bend-Insensitive 10Gb/s

Multimode Fibers based on BendBright Technology

Draka has introduced MaxCap-BB-OM3 / OM4:

���� Combining high bandwidth with low bend loss

Benefits:

- Improving high bit rate system margins

- More margin for additional connectors

���� Data centers local distribution points

- Better suited in massive cabling

- Suited for reduced size cable cabinets

Design:

Based on trench surrounding core, preventing higher order

modes from escaping under tight bends
