TEST MODES: OTDR, Auto Test, OPM, and OLS

Test Mode Icon Description

Full Auto OTDR

This is the recommended mode for users who are not familiar with OTDR operation. In the Full Auto mode, OTDR parameters such as Range, Pulse Width, and Averaging Time are set automatically. Tests are done at two wavelengths and always include an Event Table and Summary page. Pass/Fail Thresholds are set to default=[On] with an option to be turned off (values cannot be changed).Note: in the Expert mode, the Events Menu contains Event Threshold and Pass/Fail Threshold Settings allowing the user to change these settings as well as turn them on or off.

Real-Time OTDR

This is the best mode for real-time troubleshooting. Note that the Wavelength setting can only be set to individual wavelengths. The Range, Pulse Width, and Filter parameters are set by the user.

Expert OTDR

This mode is available for experienced users. It provides the most setup flexibility. Users can set Range, Pulse Width, and Averaging Time manually (Setup = Manual) or automatically (Setup = Auto Once or Setup = Auto). Users can either enable the event table (Events = Auto) or disable the event table (Events = Off). Note: in the Expert mode, the Events Menu contains Event Threshold and Pass/Fail Threshold Settings allowing the user to change these settings and turn them on or off.

OPM This mode is available to perform Optical Power Meter measurements.

Auto Test Used to perform certification optical loss tests on pairs of fibers in one or two directions. Test to TIA, ISO, EN cabling standards, User defined rules and application standards.

OLS Used with an Optical Power Meter (OPM) to perform insertion loss measurements on fiber optic links.

UTILITY MODES: Results, Settings, and New Job

Results This mode provides the file manager functions to handle the results of OTDR, Auto Test, OPM tests and to set up Jobs.

Settings This mode allows the user to adjust General Settings (Language, Distance Units, Sounds, Auto Off function, Date/Time, Company Name) and displays the OTDR version information.

New Job This mode is available for creating new jobs (setting up a file structure and defining the fiber under test location: Drives, Folders, Jobs, Routes [End Locations], Cables, Test Equipment Location, and Operators).

Setup: Expert Mode Settings

In addition to Core Settings (see Full Auto Mode settings), the Expert test mode allows you to set the Wavelength, Range, Pulse Width, Averaging Time, and Filter parameters.

Setup - Auto

Setup - Manual

Setup - Auto Once

If set to [Auto], OTDR sets Range, Pulse Width, Time, and Filter for each test. If set to [Auto Once], OTDR sets Range,

Pulse Width, Time, and Filter for the first test. After test, returns user to OTDR Home page in Manual mode, where user may change any setting for next tests.

If set to [Manual], you will need to set Range, Pulse, Time, and Filter

Use arrows to display the desired value or option

Use arrows to select a single wavelength or dual wavelengths

Use arrows to select a single wavelength or dual wavelengths for next tests.

14

Setup - Manual (continued)

Note: The Range, Pulse Width, and Averaging Time parameters are user-selectable if the [Setup] parameter is set to [Manual].

Range The Range parameter determines the distance range of the full (unzoomed) trace. It also determines Resolution - the distance between data points in the trace: the longer the range, the wider the data point spacing. We recommend selecting the shortest distance range that is longer than the fiber under test. For example, to test a fiber that is 1.5 km long (including launch and receive cables), select the 2 km range. Available Range values:

Wavelength (nm) Distance Range Resolution (set by OTDR)MM 850, MM 1300SM 1310, SM 1550

2 km (6561ft) 0.125 m (0.41 ft)

< 4 km (13123 ft) 0.25 m (0.82 ft)

8 km (26246 ft) 0.5 m (1.64 ft)

16 km (52493 ft) 1 m (3.28 ft) 32 km (104986 ft) range/16 km (range/5249 ft)

Pulse Width

The C850 OTDR can operate using different pulse widths. Short pulse widths provide the shortest event and attenuation dead zones. Long pulse widths provide the best event detection on long fibers.

Averaging Time

The [Time] parameter determines the duration of a timed test. Available time settings: 5 • 10 • 30 • 60 • 90 • 180 sec

Setup: Real-Time Mode SettingsIn addition to Core Settings, the Real Time mode allows you to set the Wavelength, Range, Pulse Width, and Filter parameters.

OPM Operation - Testing Multimode/Single-mode Links

Step I - Set the Reference (One Jumper Method)From the Main Menu, select the OPM (optical power meter) test mode. Turn on your OLS (optical 1 light source) and allow the light source to stabilize (minimum of 15 minutes).

If not using the [Wave ID] feature, set both instruments to the desired test wavelength.2

Select the appropriate fiber optic transmit and receive test jumpers. The fiber type of these 3 jumpers must match the fiber type of the link to be tested.

Perform one of the following:4

For Multimode testing: wrap and secure the transmit jumper five times around the •appropriate diameter mandrel.For Single-mode testing: make a loop in a transmit jumper and secure it with a piece of tape. •TIA testing - 30 mm loop IS0 testing - 30-50 mm loop

Note: Clean both ends of the transmit jumper.

Connect the transmit jumper to the appropriate (MM or SM) output port of the OLS. 5

Mount an adapter cap on the OPM port that matches the free connector on the transmit jumper. 6

Connect the free end of the transmit jumper to the OPM port.7

If measured output power is outside of the normal range (specified by manufacturer), clean all 8 fiber connections or replace the transmit jumper. Repeat steps 4 - 7.

To set the reference level at the current wavelength, perform the following:9

On the equipment operating in OPM mode, press the [Reference] soft key, select [Set Ref], •then press key.

The Reference value will be displayed briefly in dBm ( • mw).

Then the screen will toggle to display Loss values of the active wavelength(s) - nominally •0.00 dB.

Step II - Verify Test Jumpers Disconnect the transmit jumper from the OPM test port.10

Note: Do not disturb the transmit jumper at the OLS end.

If necessary, change the OPM adapter cap to match the connector on the receive jumper that 11 will be connected to the OPM test port.

Note: Clean both ends of the receive jumper.

Connect the receive jumper to the OPM test port.12

Mate the free ends of the transmit and receive jumpers using an appropriate adapter. 13

Verify that the insertion loss of this mated connector pair is under 0.75 dB, the maximum 14 allowed by the TIA and ISO (0.4 - 0.5 dB typical), as follows:

Observe • the displayed loss level. This is the mated connector pair insertion loss of the test jumpers in [dB].

If the insertion loss is not acceptable, disconnect the transmit and receive jumpers at the •adapter, clean the free ends of both test jumpers and repeat steps 12 & 13.

If the insertion loss is still not acceptable, replace both test jumpers and repeat steps 1-13. •

If the insertion loss is acceptable, disconnect the transmit and receive jumpers at the adapter.15

53

Move the OPM and OLS to opposite ends of the link to be tested.16

Step III - Measure Link Insertion LossConnect the free ends of the transmit and receive jumpers to the link under test.17

Note: Clean jumper end that connects to patch panel prior to every test.

The OPM will measure and display the insertion loss of the link under test.18

Press the [Save] key on the OPM to save the displayed measurement.19

Recommended AccessoriesFiber Optic Test Cables and JumpersFiber optic test cables are necessary to connect an OTDR to the fiber under test (FUT). Test cables must have the same core and cladding size as the FUT. The connector at one end of the test cable must mate with the appropriate optical port on the OTDR. The connector on the other end must mate with the fiber optic link under test.

Launch and Receive cables are required to measure the insertion loss and reflectance of the near-end and far-end connectors respectively, of the fiber link being tested. Noyes Fiber Rings may be used as Launch and Receive cables. Fiber Rings with a variety of lengths and connector styles are available from AFL Telecommunications. The table on the next page will help in selecting the right test jumpers or cables for testing.

Cleaning Tips

Clean Test Cables and FUTIt is important to keep connector end-faces on the launch and receive cables and those on the Fiber Under Test (FUT) clean, to ensure accurate measurements and operation.

IMPORTANT! Inspect optical connectors after cleaning to ensure cleaning was successful and to verify the end-face is not damaged (cracked, pitted, etc.).

CAUTION! Never view a live fiber. Laser radiation is harmful to eyes.

Follow your company’s approved cleaning procedures.

AFL recommends cleaning test cables using a Cletop cassette cleaner or a One-Click Cleaner.

Cleaning the Optical PortsCAUTION! Before conducting the following procedures be sure to have the OTDR turned OFF.

Cleaning the OTDR and VFL optical ports without removing the adapters

AFL One-Click Cleaner method

Remove the protective dust cover from the tip of the One-Click Cleaner. •

Insert the tip of the One-Click Cleaner into the optical port adapter and gently press the body of •the One-Click Cleaner until an audible “click” is heard.

Remove the One-Click Cleaner. •

AFL FCC2 fluid and CCT stick method

Lean a can of FCC2 back (30°), press the button on FCC2 to fill the well. •

Dip a CCT stick into the well of the FCC2 to dampen the tip with optical cleaning fluid. •

Place the damp tip over the ferrule to be cleaned. •

Rotate the tip clockwise 10 revolutions while applying varying pressure to create a gentle •pumping action where the tip contacts the ferrule.

Discard the CCT stick after using both tips. •

63

Cleaning the optical ports with adapters removed

Removing connector adapters for cleaning and inspection

To access the OTDR Port

Rotate the adapter base counterclockwise approximately four times. •

Pull the adapter directly out away from the universal adapter mount to expose the ferrule. •

To access the VFL Port

Unscrew the adapter counterclockwise and pull the adapter straight out to expose the ferrule.

To access the OPM Port

Unscrew the adapter cap from the adapter cap mount.

Cleaning the Exposed Ferrule or the OPM port

Use lint-free optical cleaning wipes such as AFL FiberWipes and optical quality cleaning fluid such as AFL FCC2 connector cleaning fluid.

Note: if using isopropyl alcohol (IPA), be sure to use 99% pure IPA that has not been contaminated.

Dampen a portion of the wipe with the cleaning fluid.1

Gently wipe the exposed ferrule (OPM port) starting with the wet section of the wipe and pulling 2 it to the dry section.

Note: • Starting with the wet cleaning and finishing in the dry improves cleaning action, reduces static buildup, and finishes with the end-face dry.

Cleaning the adapters

Method 1:

Insert a Cletop adapter cleaning stick into the sleeve of the adapter and rotate 10 times. 1

Remove.2

After cleaning the adapter, replace the adapter over the ferrule; centering it onto the alignment 3 pin.

Tighten the adapter base.4

Method 2:

Use a can of filtered compressed air (held vertically), blow out any contaminates from the 1 adapter.

After cleaning the adapter, replace the adapter over the ferrule; centering it onto the alignment 2 pin.

Tighten the adapter base.3

FAQs OTDR Testing Tips

Why do I need to use a launch and receive cable? A launch cable allows the OTDR to settle down after the initial pulse and provides a reference cable for testing the first connector on the fiber under test. A receive cable provides a reference cable for testing the last connector of the fiber under test.

What is the purpose of the Real-Time Mode?With a launch cable, the Real-Time mode may be used to quickly view many short fiber links. It can also be used to quickly “trace” short fiber links.

What is the advantage of the Expert Auto Mode?User is able to select a single l and have the OTDR set the other test parameters.

What is the advantage of the Expert Auto Once Mode?User is able to select one or more wavelengths, let the OTDR select Pulse Width, Time, and Range for one test. Then allow the user to adjust any of these test parameters for the next test(s).

Can I save traces for viewing later?Yes. There is a dedicated Save key. In the Main Menu “File Tab”, set up the location/folder (Internal or USB) to save the file, the file naming format, and fiber number. The fiber number will automatically increment after each trace is saved.

Test in feet or meters?If you know your fiber distances in feet, it may be beneficial to measure distances to events/faults in feet.

Fiber loss specifications are given in dB/km. Therefore it is often beneficial to measure fibers in meters/kilometers when loss results are required.

Expert OTDR Setup

RANGE: LengthToo Short: you will not capture the entire •fiber length

Too Long: trace will be squashed to left •side of Screen

Good Range: 1.5 to 2 times length of •actual fiber

PULSE WIDTH:Too Narrow: trace disappears into noise •floor before end of fiber is reached

Too Wide: events can not be resolved •

Good Pulse Width: Events can be seen •and trace is smooth

AVERAGES:Too Few: Trace is noisy, trace floor is •too high

Too Many: Trace is smooth but wastes •time

Good Number of Averages: smooth trace •

65

The batteries may be charged while the OTDR is switched on or off by attaching an AC power adapter.

Plug the AC adapter/charger into a •standard wall outlet.

Connect the AC adapter/charger to •the Power port located on the OTDR side panel.

The [AC/Charger] indicator on the •front panel will turn on [Red].

Charge batteries until the [AC/ •Charger] indicator turns [Green].

Note: an external battery charger and spare batteries are available
