Laser Radiation: To avoid serious eye injury, never look directly
into the optical outputs of fiber optic network equipment, test
equipment,
 Always avoid looking directly into the optical output port,

when the instrument is working

 Always replace protective dust cap on the detector port when

the instrument is not in use.

 Always avoid looking directly at unconnected end of optic

Automatic Wavelength Identification

Compatible with the digital encryption protocols of its laser source module and
Shineway SLS-50 Series Stabilized Laser Source, OLT-55 can automatically identify
the wavelength of the input optical signal and switch to the corresponding test mode,
which greatly reduces the workload at both ends and avoids potential error.

Automatic Bidirectional Loss Test on Single Fiber

Two OLT-55 at both ends of a single optical fiber can perform bidirectional loss test by
just pressing one and can automatically measure and display the entire fiber
attenuation to help users acquire complete and accurate optical fiber loss information.

Applicable to FTTx/PON testing

OLT-55 can be applied to measure Triple-play signals (1310nm, 1490nm and 1550nm)
on Passive Optical Network (PON)

2. Basic Operation

2.1 Foreword

This part introduces the basic operation on OLT-55. Specific operations are elaborated in Chapter 3 of this
manual. Please read this manual carefully for optimal operation. If you encounter any problems during
operation, you are welcome to contact the technical staff of our company or representatives.

2.2 Instrument Details

2.2.1 External Interfaces

1. Optical Input & Output

OLT-55 is available with FC connector (Interchangeable SC/ST).
Note: Output port is marked with “LS”; Input port is marked with “PM”.

2.3 Use of Battery

OLT-55 works on lithium battery. Please make sure battery is mounted properly before use. When battery is
low, low battery indicator will appear on LCD. You can still use OLT-55 as long as its display on LCD is
identifiable. When LCD display becomes dim, laser source output will become unstable and power meter
measurement will be inaccurate. Please charge as soon as possible when battery is low to ensure accurate
measurement.

Please take out the battery if OLT-55 is not in use for a long time.

2.4 Connector Cleaning

Please follow the instructions below when cleaning:

 Turn off the instrument before cleaning.
 Non-compliant operation may result in hazardous radiation exposure.
 Turn off laser source before cleaning optical interface.
 Always avoid looking directly into the optical output port when the instrument is working, laser is

invisible and can cause serious eye damage.

 Disconnect instrument from power supply before cleaning to prevent electric shock.
 Do not install unauthorized parts or make unauthorized adjustments on instrument.
 Please consult qualified professional about maintenance and repair services.

Always clean optical connector before using OLT-55 to ensure accurate measurement.
Clean the optical connector gently with cleaning swab.

Inappropriate maintenance may result in low performance or error:

 Distance error increases;
 Linearity error;
 Extra optical power attenuation;
 Received optical power is beyond normal range.
