_ › Q44-1M34CNU

QUATRA 4000c Coverage Unit (CU)

The Coverage Unit (CU) is the remote unit of the system that rebroadcasts the donor signal. The cost efficient and easy-to-deploy system leverages Power over Ethernet (PoE) for up to six CUs.
- Provides coverage throughout facility (up to six per Network Unit)
- Power delivered by Power over Ethernet from the Network Unit
- Self-configuring and self-optimizing
- Only compatible with CEL-FI QUATRA 4000c NU
Model Number:
_ › Q41-RECU
QUATRA 4000 Fiber Hub
The CEL-FI QUATRA 4000 Fiber Hub expands the Network Unit capacity from six to up to twelve Coverage Units. The Fiber Hub can be installed 2.0 km (1.24 M) away from the NU to cover large spaces while maintaining the same signal quality throughout the system.
- Donor source over fiber
- FCC certified
- SFP+ module not included
