Infrastructure Preparation MobileAccess™ 1000/1200
8 UM-1000, Revision 2.2
Chapter 2. 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.
