5.1 Fiber Inspection and Test – Simplex/Duplex
5.1.1 Overview
Every fiber connection is a potential point of failure should the end face of the mated fibers be dirty or
damaged. Proper handling as well as inspection and cleaning techniques are imperative. The best practice
is to Inspect Before You Connect (IBYC). Trace the steps on the flow chart below. Always inspect before
that first cleaning attempt. If the end face is already pristine, the redundant cleaning effort could introduce
a problem.
Most Operators require fiber inspection of every end face in the path to the IEC-61300-3-35 Standard.
The VIAVI P5000i and FiberChek Pro both provide automated pass/fail analysis to this standard.

The FiberChek Probe and P5000i use the same adapters for the various interfaces you will encounter.
Study the following table for proper adapter tips and cleaning options.
Inspect Before You Connect
When you are building or
troubleshooting a site, it is all about
eliminating possible sources of
problems. Making sure fibers AND ports
(Bulkheads and SFPs) are clean and
undamaged is a quick and simple step
that should be undertaken as soon as
the decision is made to make/break any
fiber connections.

Angled. The 8-degree angle on the end face creates a
superior connection in terms of reflectance and durability.
The OTDR port can be cleaned with a SC style IBC stick
cleaner (shown above). The fiber itself can be cleaned with
that as well or with wipes, CLETOP, etc. The tips for the
inspection scope have a built-in angle as well. Be sure and
inspect and then protect the cleanliness of your OTDR port
and launch fiber.

5.2 Fiber Inspection and Test - MPO
As with simplex fiber, MPO connections are a potential point of failure should the end face of the mated
fibers be dirty or damaged. However, whereas simplex fibers are a single connection, an MPO has 8-24 fiber
connections. Proper handling as well as inspection and cleaning techniques are imperative. The best
practice is to Inspect Before You Connect (IBYC). Trace the steps on the flow chart below. Always inspect
before that first cleaning attempt. If the end face is already pristine, the redundant cleaning effort could
introduce a problem.
Examples of MPO connectors on the Tower are Corning Optitip, Jonhon, CommScope HMFOC and ODC
MPO connectors.
Most Operators require fiber inspection of every end face in the path to the IEC-61300-3-35 Standard.
The MPO Sidewinder provides automated pass/fail analysis to this standard.

5.3 Continuity Test with a Visual Fault Locator
A VFL is handy device that should be in the tool kit for anyone who deals with fiber optics. Use it to inject
visible red light through a fiber under test up to 5 km on single-mode fiber. Seeing the red light at the far
end of the fiber proves to the observer that there is continuity. It also resolves the “Are we on the same
fiber?” question. If it is a short fiber or fiber jumper, you can also look along the length of it for any red
light escaping from a bend, break, or cut.
When installing a fiber system for a macro cell site, the VFL is a time saver. When testing each TX/RX fiber
pair, a loopback device or cable can be placed at the far (usually the RU end) of the fiber pair. The VFL’s red
light is shined up one fiber and returns on the other. If it does not, the person at the far end might notice
the red light coming from a fiber other than where they connected the loopback and make the adjustment.
An FFL-050 VFL is shown below left. Below right shows a simplex coupler for connecting the VFL through a
short jumper. The duplex fiber in the right portion of the picture is eventually looped back and the red light
comes out of the other fiber in the pair. The back of business card is held there just to show this for a
photograph.

The picture below shows as example of the LC Duplex connector at the RU end of the tower top jumper. A
duplex coupler can be used to then connect a simplex fiber as a loopback.
Once Continuity is proven with a VFL you can move on to an Optical Insertion Loss Measurement or an
OTDR Measurement.
5.4 Optical Insertion Loss
This is a measurement of the total optical power loss from the beginning to the end of the fiber system. In
a tower or rooftop site during construction, this would typically be from the bottom, to the top, through a
loopback cable or device, and back to the bottom. This speeds up and simplifies the test by keeping the
Source and Meter at ground level. On a 12-pair hybrid, this also cuts the test count from 24 to 12. This
step comes immediately after IBYC and creating the loopback and proving continuity with the VFL (see
above). However, if an OTDR is available, skip the Optical Insertion Loss test because a system loss
expressed in dB is one of the results that an OTDR provides. Doing both tests would be redundant. Use the
Insertion Loss Test as part of a spot check at the warehouse or on the ground before hoisting. The use of an
OTDR test is recommended for final close-out. The OTDR provides the system loss information as well as
the per event reflectance and per event loss information required.
Most Operators expect a round trip Insertion Loss (IL) value to be less than 3 dB (half power loss)

5.4.1 Tools: ONA-800 OTDR with Optical Source (CW) and USB Optical Power Meter (MP-
60/80)
This test has 2 steps.
1) (Left picture below) As always, IBYC. Then the Light Source and the MP-60/80 Power Meter needs
to be connected to each other using the clean test leads that will be used in the actual test. Use
1310 nm for Single Mode Fiber. Regardless of the absolute power from the source (in dBm) the
Power Meter is referenced to 0 dB. This also negates any losses from the test leads themselves.
2) (Right picture below) Now the Light Source and Power Meter are connected to the system under
test using the same test fibers that have been referenced out. The loopback established in the
Continuity Test earlier is still in place. Read the value on the power meter. It will be expressed in

Page 18 of 43
dB to indicate loss as compared to the reference test. We expect a negative value close to 0.
Anything better than 3 dB of loss is passing.
1 – Referencing of the Test/Jumper Cables 2 – Connecting to System under test
There are many Power Meters that could be used for this test. The one shown above is the MP-60A Power
Meter plugged into the ONA-800. It is screen-less device with a USB connection to be plugged into a ONA-
800 (display shown on left) in these illustrations. Both examples are passing because the result is that the
loss is less than 3dB. Read that as NOT more negative than 3dB.
