1．Overview
XtendLan makes full use of OTDR work principle to design and
develop the XL-FR330 fiber ranger and greatly improves the
performance from outside design to inside functions.
In hardware, it is lightweight, rugged, dustproof and waterproof.
In software, it has three brilliant functions.
One is Automatic Power Control, which automatically test and
adjust the best power level according to the real test
environment;.
Secondly, it is Automatic Pulse Width Selection which
automatically select most suitable pulse width according to the
real test distance.
Thirdly, it has built-in 650nm VFL, with which it can detect the
fault from 1-10km and finally realize the one-dead zone test
over the full range.
All these functions make the test easier, more accurate and
perfect tool for the field work.
Features
More accurate and better repeatability.
List Max 8 results of each test
Easy to identify the faults location
Built-in visual fault locator with optional output power
Optional interchangeable connector
More than 10 hours long battery life
Applications
Testing the fiber length and locate the faults.
Locates the distance between two connection points.
Installation, maintenance and fault location of FTTX and Access

Press this key to turn on/off..
Under the standby state, press this key to turn on the auto-off
function, under which the unit will turn off automatically after
5 minutes idle time.
Under the test mode, press this key to test the under- test
fiber and display the results in the screen. Press this key for
5s to enter the automatic cycle test mode and “A” will be
showed in the top left corner of the screen. Press this key
again to exit the automatic cycle test mode.
Under the test mode, press this key to review the previous
test results. Under the refractive index changing mode,
press this key to increase the value of refractive index by
0.0001.
Under the test mode, press this key to review the latter test
results. Under the refractive index changing mode, press
this key to decrease the value of refractive index by
0.0001。
Under the test mode, press this key to review the current
refractive index or change the values together
with“▲/▼”keys. Press this key again to save the values and
go back to the test mode.
Press this key to activate the VFL function

4．2．1 Turn on the unit and enter the test mode.
Version No.
4．2．2 Clean the under-test fiber and connect it to the OTDR port.
Please choose the correct the fiber connect before connecting.
4．2．3 Press“SCAN” to review the fiber and show the scanning
progress in the screen. With the Auto Pulse Width Control Function,
the unit will set the best pulse width during the scanning process and
find the events within the test range.

4．2．4 After the test, it will show the total test results.
The maximum listable events are 8pcs.Press “▲/▼” to review the total
events. The error of the reflection events is smaller; and the error of the
attenuation events is relatively larger.

4．2．6 When repairing the fiber, people could use this unit to
identify the location of the breaks or do the automatic cycle test.
Press “Scan”, unit it shows “Scan” in the screen.。

4．2．8 The unit starts to test 5s later. When the break is successfully
repaired, a different value will be showed in the screen.
4．2．9 Press “SCAN” again to exit automatic cycle test。
4．2．10 Press“IOR”to enter the refractive index changing mode.

4．2．11 The refractive index ranges from 1.0000-2.0000.Press
“▲/▼” keys to change the values and press ”IOR” key to save and
exit the changing mode.
4．2．12 The VFL could be used for location of the short-distance fiber
faults. Before using the function, please make sure that it is not under
the automatic cycle test mode. Connect the fiber to the VFL output port
and press “650nm” key, a visible red beam could been seen at the
breaking point or end –face of the tested fiber. Press “650nm” again to
exit the VFL mode.
Breaking Point
Notice: Visible light source is harmful to the eyes. Do not look at
the breaking point or end face of the tested fiber directly.

5．Maintenance
Keep the fiber output ports clean.
Please clean them regularly with the pure Alcohol
Keep the dust-proof cap clean and cover it after the test.
Turn off the unit and keep the output ports inactive when
cleaning. Otherwise, it will lead to dangerous radiation harms。
Choose the correct fiber connector before test。
Take out the batteries when not in use for a long time。
Cleaning Swab
Dip the cleaning swab in the pure alcohol and clean the connector
gently, then clean it again with dry cleaning swab

7. Notices
There are laser and sensor inside the unit. Please do not point
the optical sources to the sensors directly, otherwise the
sensor will be damaged.
Do not expose the unit to the sun directly。
Do not look at the output ports directly when it is turned on。
Before “scanning”, ensure the tested fiber is well connected to
the “OTDR port” or “VFL port”. Do not plug in/out the fiber
during the test.
