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
Fiber Cladding
50 µm Core
Trench
Macrobending:
High-order modes
(outer range of core) are
better confined at bends:
overall macro-bending
