Fiber Optic Rules
• Either single mode or multimode fiber can be used with MobileAccess2000M products,
while MobileAccess2000 products can only be used with single mode fiber.
• Only Multimode fiber, 50/125 or 62.5/125um complying with ANSI/TIA/EIA-568-B series,
EN50173-1 or ISO/IEC 11801 can be used. The fiber length can be up to 300 meters
assuming the following qualifications:
 All fiber in a given length of fiber must be of the same core diameter.
 All Bulkhead adapters must be Single mode SC/APC (Green) adapters.
 All terminations cross connections or patches must be direct fusion splice or
MobileAccess specified patch cords listed below.

• Use only 8-degree 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, or connecting fiber optic cables.
• 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.
• All fiber optic connections should be cleaned prior to attaching to termination points
using a dry cleaning device (i.e. Cletop or equivalent).
• Fiber connector protective caps should be installed on all non-terminated fibers and
removed just before they are terminated.
• Verify the Fiber Optic connections. You may use the Optical Test Procedure described at
the end of this manual.
• Pay special attention while connecting the SC/APC connectors - you must hear the “click”
when the connection is made.
RF Rules
• Use coax RG223, 50ohm, male-to-male N-type for RF connections from the BUs to the
BTS/RBS and to the RIU.
