Test Procedures Overview
The following section will provide an overview of the workow and recommended procedures for
each test that can be performed with the TTK 720 kit. Some procedures may have more importance
placed on them by the carrier: please use these procedures only as a guideline. Wireless carrier
requirements supersede ODM’s recommended procedures in all circumstances.
This section explains how to properly maintain the TTK 720 test kit components between uses.
VIS 300C charging, equipment cleaning, and storage are discussed.
Proper Equipment Care Between Uses
1
When arriving at a new test site or when starting a new project, the user should create a new “Project
Folder” on the VIS 300C unit. This stores all relevant site information (scope images, loss readings, etc.
in one place. This section covers setting up for a new test site.

Fiber inspection should be performed before making any connections onsite. Analysis and saving of
images may be required for closeout packages. This section explains how to inspect and clean ber.
Fiber Scoping
3
Also known as “insertion loss” or “ber sweep” testing, dB loss testing allows the technician to validate
that all ber pairs are in working condition. Saving of dB loss test results may be required for closeout
packages. This section explains the necessary steps for testing ber.

4
An onboard red laser allows users to verify proper continuity of ber cables. This is a troubleshooting
task only. This section gives an overview of the VFL functionality.

The VIS 300C has built-in report creation software. This section explains how to create reports for
closeout packages.

1a - Charging the VIS 300C
The VIS 300C charger comes in two pieces. See diagram below. The cable on the right will be
plugged into the power brick to create the charging device.
Allow the VIS 300C to charge fully between uses. The VIS 300C can be used while charging;
please be aware that an internal fan may activate to regulate temperature. 4-5 hours battery
life typical for a single charge.

1b - Cleaning the DLS 355
The DLS 355 laser source is a high-end test laser, capable of outputting 1310 and 1550nm
wavelengths. The output port of this unit utilizes a physical connection, which means that it
can become soiled if used improperly. When needed, the DLS 355 adapter may be removed for
inspection and cleaning of the ber ferrule.

freely, then pull o.
Inspect ferrule with
VIS 300C and clean
with appropriate tools.
Always replace adapter.
Regular inspection and cleaning of the output port of the DLS 355 may not be necessary if
appropriate procedures are followed. Always inspect test jumpers before they are plugged into
the DLS 355 and store it properly to ensure continued performance.

1c - Inspecting and Cleaning Fiber Jumpers and Loopback
Special care should be taken to ensure the continued function of all test jumpers and
loopbacks. A regular inspection and cleaning regimen will keep kit components functional for a
longer period of time.

indicates a ber ferrule that should be
inspected and cleaned between uses.

1d - Equipment Storage
All equipment should be stored in the airtight case provided by ODM. Keep the case in a cool,
dry location and remove battery from the DLS 355 if it must be stored for over 6 weeks.
