T-BERD®/MTS-5800 Modular Test Set
E4100 OTDR Module Optical Light Source option
This procedure describes how to use an E4100-series OTDR module as an Optical Light Source (OLS). If
optioned, the OTDR module can operate as an OLS or Optical Power Meter, but not both at the same
time.
Equipment Requirements:
•T-BERD/MTS-5800 equipped with the
following:
oFiber Optics Software Release V17.22
or greater
oE4100 Series OTDR Module
oE41OTDRLS Light Source option
•Fiber optic cleaning and inspection tools
•Launch Cable (patch cord) with
connectors matching the OTDR port and
Fiber Under Test
•Optical Coupler to connect Launch Cable
to Fiber Under Test
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Type of Fiber (Multimode or Single Mode)
•Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
•Wavelength(s) to be tested (850nm, 1300nm, 1310nm, 1550nm, etc.)
Fiber Inspection Guidelines:
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (OTDR Port,
Launch Cable, bulkhead connectors,
patch cords, etc.)
•Focus the fiber on the screen. If dirty,
clean the connector.
•If it appears clean, run inspection test.
•If it fails, clean the fiber and re-run
inspection test. Repeat until it passes.

Connect to Fiber Under Test (FUT):
All fibers and connectors should be inspected
and clean prior to connection, as described on
page 1. The Light Source may be connected to
the FUT via an optical patch panel (OPP) or an
optical coupler:
1. If the interface to the FUT is a patch
cord, connect the patch cord to an
optical coupler with the same connector
type.
2. Inspect the FUT connected to the
coupler or OPP.
3. Inspect the other fiber end face of the
Launch Cable.
4. Connect the Launch Cable to the coupler or
OPP.
