Optical Connectors

The test platform displays a laser warning icon when the laser source is active to alert the user

about a potentially dangerous situation. Make sure that optical sources are inactive before

connecting fiber to the test set to avoid skin or eye damage, or damage to the unit. It is

recommended to:

• Deactivate the laser before connecting or disconnecting optical cables or patchcords.

• Never look directly into an optical patchcord or an optical interface (e.g. CFP, CFP2, CFP4,

QSFP+, SFP+, SFP, OTDR, LS, VFL) while the laser is enabled. Even though optical

transceivers are typically fitted with Class 1 lasers, which are considered eye safe, optical

radiation for an extended period can cause irreparable damage to the eyes.

• Never use a fiber microscope to check the optical connectors when the laser source is

active.

Electrical Connectors

Telephone lines may carry dangerous voltages. Always connect the electrical test ports to

known test interfaces which carry low level signals.

3.0 Introduction

The FX80 power meter is designed to test passive optical networks (PON). It is used to

simultaneously measure all optical signal levels between the Optical Line Terminal (OLT) and

the Optical Network Unit/Terminal (ONU/ONT) on Gigabit B/E/GPON type networks. It can be

connected onto the PON network at any available access point along the Optical Distribution

Network (ODN). The access point can be at the OLT (central office - CO, head end or sub-

headend or remote hut), Fiber Distribution Point (FDP 1 or 2/splitter (if connectorized) or at the

ONU/ONT (customer premises - CP). The figure in Section 6.2.3 Performing Optical Power

Measurements in PON shows a typical PON with the three possible locations for

measurement.

The unit passively monitors 1310, 1490 and optional 1550 nm RF video downstream and

upstream PON optical power levels for compliance to standards. The measurement results can

be transferred to a PC or uploaded to the cloud using a Fiberizer Cloud account.

The operator is assumed to have received basic training in fiber optics and related testing and

measurement practices.

6.2.3 Performing Optical Power Measurements in PON

Clean the fiber before connecting it to the device.

FX80 PON Optical Power Meter User Manual Page 17 of 38

A typical passive optical network (PON) with possible points of measurement

To measure optical power in the passive optical network (PON):

1. Select the necessary mode (PON Burst for active networks, or PON CW for networks

without signals) by pressing the |MODE| button. See Section 6.1 Modes for Optical Power

Measurements for details.

2. To test a PON network, insert the FX80 at one of the following locations along the PON

network: OLT, Fiber Distribution Hub/Point (FDP) or ONU/ONT. At least one extra patchcord

is needed to perform a test. If PON network elements have SC/UPC connectors and the

FX80 has SC/APC, two hybrid patchcords are needed.

When testing at the FDP-A location, if there is no drop line installed, the 1310

nm upstream will be seen only if a fiber is temporarily connected to the ONT.

This may require two patch cords.

3. Connect the fiber with 1490/1550 nm downstream traffic to the left-side OLT test port.

Confirm that the 1490 nm signal is immediately detected. 1550 nm will appear only if the

PON network includes RF video signal traffic (RFoG). If no signal is detected, begin

troubleshooting and make sure the proper test port is connected.

4. Once a good 1490 nm signal level is detected, connect the patchcord between the FX80

ONU/ONT right-side test port and the PON network element closest to the ONU/ONT to

measure the 1310 nm upstream signal. There may be a delay in seeing a 1310nm signal. If

the ONT/ONU is power-cycled, it can take one minute or longer before the network is fully

operational. The measurement results are then shown on the screen. The example below

shows typical values one might expect when connected at the ONU (location C) and no P/F

thresholds have been set.

FX80 PON Optical Power Meter User Manual Page 18 of 38

PON Burst mode measurement results as values

If P/F thresholds have been set, the measurement results are presented as Pass or Fail (see

example below).

PON Burst mode measurement results as P/F thresholds

To switch back to actual values for the same measurement, press the |F1| (P/F) button.

FX80 PON Optical Power Meter User Manual Page 19 of 38

Switching from thresholds to values for the same measurement

With the Value line selected, press |Shift/Enter| to confirm the selection. The screen shows

the values for the same measurement.

6.3 Broadband Power Measurements (Optional)

The Broadband OPM is an InGaAs detector with a wavelength range from 850 to 1650 nm.

The displayed power readings can be absolute (dBm and watts) or relative (dB). To measure

the optical power in a fiber, insert the test fiber on the OPM test port and press |MODE| until

the PM1 or PM2 test mode appears at the upper left corner of the display.

Results of PM measurement

FX80 PON Optical Power Meter User Manual Page 20 of 38

The fiber under test must have only one wavelength. If there are several

wavelengths, the measurement results will NOT be valid.

To change the wavelength, press the |F1| (WAVE) button. The resulting calibrated wavelength

list is then shown below.

Selecting a wavelength for PM measurement

button to confirm the choice. The new wavelength then appears in the top right corner of the

display. For the previous wavelength to remain effective, select a wavelength and then press

the |F1| (EXIT) button.

If the fiber under test carries a signal with WaveID details, select [ AUTO ]. Then, the FX80

determines the wavelength automatically.

If the [ AUTO ] option for a signal without WaveID or modulated is

selected, the λ value goes blank and the measurement results are NOT

valid.

6.3.1 Setting Power Reference Level

To measure the fiber under test span loss, first set a reference level for each test wavelength.

Set the reference level by pressing the |F3| (OPTION) button.
