FTTA OTDR, Cell Tower Construction and Maintenance
This quick card explains how to connect to a fiber under test, configure Fiber to the Antenna (FTTA) OTDR
test setups, run tests, and analyze results with a VIAVI ONA-800 equipped with a 4100 series OTDR.
Equipment Requirements:
• ONA-800 equipped with the following:
o Fiber Optics Software Release V19.92 or
greater
o E4100 Series OTDR Module
o Software options for FTTA OTDR and
SmartLink Mapper (SLM) icon-based OTDR
results
• Fiber optic cleaning and inspection tools
• 20-meter fiber optic patch cable (Launch Cable)
with connectors that match the OTDR Port and
Fiber Under Test (SC UPC, SC APC, LC UPC, etc.)
• Optical Coupler to connect Launch Cable to
BBU Jumper Cable or Trunk Cable
The following information is required to complete the procedure:
• Type of Fiber (Multimode or Single Mode)
• Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
• Tower architecture:
o Is there a BBU jumper cable?
o Is there an RRU jumper cable?
• RRU and BBU/Base Station IDs
• Fiber Code (1-Rx, 1-Tx, ..., 24-Tx)
Fiber Inspection Guidelines:
• All fiber end-faces must be clean and pass an
inspection test prior to connection.
• Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (SFP Port, bulkhead
connectors, patch cables, etc.)
