Description
This Excel OM4 multimode loose tube fibre optic cable is designed for both indoor and outdoor installations, providing a robust solution for backbone, campus, building-to-building and data centre network applications where high-bandwidth fibre connectivity is required.
The cable construction features up to 24 colour-coded 50/125µm OM4 fibres housed within a gel-filled, non-drip PBT loose tube. E-glass yarn strength members provide mechanical protection, while the black LSZH (Low Smoke Zero Halogen) outer sheath offers improved fire performance for installations where reduced smoke and halogen emissions are required.
Suitable for installation in ducts, trays and external routes, the cable is rodent resistant and designed to withstand demanding installation environments while maintaining reliable optical performance.
Manufactured to recognised industry standards, this OM4 fibre cable is compatible with standard OM4 multimode fibre systems and supports high-bandwidth network infrastructure where reliable performance and durability are required.
