Small Cell Donor:
This configuration connects one or more NUs directly to a small cell through a Small Cell Interface (SCIF) for
signal distribution. Plan to mount both the small cell, SCIF and NU next to each other, and where there is easy
access to LAN cabling and routing (such as an IT closet with pre-existing LAN patch panels).

Cabling Between the Small Cell and QUATRA
The QUATRA Small Cell Interface (SCIF) shown above contains the proper amount of signal attenuation and
port isolation needed when connecting up to four (4) small cell RF ports to the RF ports of one or two QUATRA
NUs. Choose the small cell to match the overall capacity you need and match the QUATRA system size to
achieve the coverage you need. If more than two (2) QUATRA systems are to be used, contact your supplier or
www.cel-fi.com/quatra for more information.
Installation Considerations for NUs and SCIF:
• Plan to mount all NUs and the small cell in the same location so they may be properly interconnected using
the SCIF.
• The SCIF should be mounted above the Small Cell within reach of the Input RF cables.
• Make sure there is a suitable power outlet within reach of the NU power supply.
• Make sure there is room to route CU, LAN, power, and optional RF cables.
• Allow adequate ventilation.
• Do not place the NU close to other transmitting antennas.
• NU Faceplate LEDs should be clearly visible.
IMPORTA NT
To prevent damage or out of specification operation, a QUATRA Small Cell Interface (SCIF) must be
used when connecting QUATRA systems to a small cell.
The actual cabling between the small cell and QUATRA is described in the installation section of this guide.
