Infrastructure Preparation
This following installation rules are based on the assumption that site survey and
installation planning (
including power requirements
) have been completed.
2.1 Basic Installation Rules
2.1.1 Fiber Optic Rules
•
Use only single mode fiber for indoor applications.
•
Use
only
SC/APC connectors (green color).
•
Use
only
fusion splice for connecting two fibers.
•
Use minimum splicing/connectors to achieve minimum losses on the fibers
(<0.5dB).
•
Use precaution while installing, bending, connecting fiber optic.
•
Use an optical power meter and OTDR for checking the fiber optic cables.
•
Make sure the environment is
clean
while connecting/splicing fiber optic
cables.
•
Verify the Fiber Optic connections. You may use the Optical Test Procedure
described in
Appendix I: Optical Test Procedure.
•
Pay special attention while connecting the SC/APC connectors - you must
hear the “click” when the connection is made.
2.1.2 RF Rules
•
Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz)
for connecting to RHU ports.
•
Use coax RG223, 50ohm, male-to-male N-type for connecting RF side from
the Base Unit to the BTS/RBS side.
•
When using the MobileAccess™ system in an environment in which other
indoor coverage systems are installed, pay special attention to the isolation
between antennas (
distance must exceed 2 meter
).
•
Use special attention while bending coax cables, according the coax
specification.
•
Use any antennas suitable to the desired frequency.
•
Use VSWR meter (Site Master) for checking coax cables, including the
antennas. (<2).
•
Unused
RHU
and
RIU
ports should be terminated with a 50ohm load.
