IntroduCtIon to FIber InspeCtIon
Contamination is the number 1 reason for
troubleshooting optical networks. A single
particle mated into the core of a fiber can cause
significant back reflection, insertion loss, and
equipment damage. Visual inspection is the only way
to determine if fiber connectors are truly clean before
mating them.
The JDSU video fiber inspection probe and handheld
display system is used to quickly and easily inspect
connector end faces, which ultimately minimizes
signal loss and optimizes test conditions. Westover
FBP-series video probes, available in digital or analog and single- or dual-magnification (200/400X), are high-
performance handheld microscopes designed for inspecting both female (bulkhead) and male (patch cord)
connectors, as well as other optical devices. The probe microscope can also be combined with a USB converter
module to inspect connectors via compatible test platforms and PC/laptop. This versatile system offers a wide
range of configurable solutions that can meet the demands of any application.
Our comprehensive selection of precision, stainless-steel fiber inspection tips and adapters are carefully
engineered to produce consistent and accurate results. They are interchangeable and designed with a unique
optics architecture that enables the probe to interface with every connector and application in your network.
Implementing a simple yet important process of
proactively inspecting and cleaning before mating
can prevent poor signal performance and equipment
damage.

Is It Clean? IS IT CLEAN
1. Count/measure the particles/contamination that are on the fiber surface.
2. Estimate or use a grading overlay to grade the fiber by determining the number and size of each particle
present in each of the 4 fiber zones.
Dirt is everywhere, and a typical dust particle (2–15 μm in diameter) can significantly
affect signal performance and cause permanent damage to the fiber end face. Most
Zones are a series of concentric circles that identify areas of interest on the connector end face. The inner-most
zones are more sensitive to contamination than the outer zones.
Acceptance criteria are a series of failure thresholds that define contamination limits for each zone.
A. Core Zone
B. Cladding Zone
C. Adhesive / Epoxy Zone*
D. Contact / Ferrule Zone
field test failures can be attributed to dirty connectors, and most connectors are not inspected until the problem is
detected, after permanent damage has already occurred.
*Note: In most cases, there are no limits to the number/size of
contamination present on Zone C (Adhesive/Epoxy).
If acceptable, do not touch it and CONNECT.
If not acceptable, CLEAN.

ConneCt CONNECT
Clean Connection
CoreCladding
Light Transmitted
There are 3 basic principles that are critical to
achieving an efficient fiber optic connection:
1. Perfect Core Alignment
2. Physical Contact
3. Pristine Connector Interface
Today’s connector design and production techniques have eliminated most of the challenges to achieving core
alignment and physical contact.
What remains challenging is maintaining a pristine end face. As a result, CONTAMINATION is the #1 reason for
troubleshooting optical networks.
Optical connections are made for one of two reasons:
1. Completing a System Light Path (TX to RX)
Connectors are used extensively throughout optical networks. They give us the ability to re-configure the
network and provision services. If contamination is present in the light path, system performance will be
degraded.
Note: Always inspect and, if necessary, clean the contamination from the optical port and optical cable
before connecting.
2. Connecting a Test Device to Part of the System
Test devices are frequently connected and disconnected to elements of the network. Often, test leads are
systematically connected to each port in a network element in sequence. This duty cycle makes test leads
especially prone to contamination and damage. If a test lead is contaminated, it can quickly spread that
contamination through a large portion of the network.
Note: Always inspect and, if necessary, clean the contamination from the network port and test lead before
connecting.
