T-BERD 5800 Network Tester
C37.94 Bit Error Rate Testing (BERT)
This quick card describes how to configure and run a C37.94 Optical Bit Error Rate Test to a hard loop
or another similarly configured T-BERD/MTS 5800.
Equipment Requirements:
• T-BERD 5800 equipped with the following:
o BERT software release V27.2 or
greater
o C5C3794 ITU C37.94 Optical BERT
option
o C37.94 capable optical transceiver
(SFP) to match the line under test
• Patch cables to match the optical
transceiver and the line under test
• Fiber optic inspection microscope
(P5000i or FiberChek Probe)
• Fiber optic cleaning supplies
Figure 1: Equipment Requirements
The following information is required to complete the test:
• Clock Source (Internal or Recovered)
• Data Rate (Number of 64K Channels)
• Test Pattern(s)
• BER Pass/Fail Threshold
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 cords, etc.)
