The DLS 355 dual laser source is a single-mode test laser used for verifying the proper
function of fiber optic networks. This document will serve as an overview of the major
features and functions of the device and oer tips for troubleshooting common issues in
optical networks.

1. Connector Adapter - Interchangeable
The DLS 355 comes with an SC screw-on adapter. Additional adapters are available from
Ripley. Refer to page 5 for more information.
2. Wavelength Indicator
This unit oers 1310 nm and 1550 nm wavelengths. When the DLS 355 is turned on, the red
light indicates which wavelength is selected. The red light blinks to indicate when the 2 kHz
modulation is turned ON.
3. Low Battery Indicator
A red indicator light appears when the CR2 battery power is low. Replace or recharge the
battery, depending on the battery type, to return to normal operation of the DLS 355.
4. Power Button
Use the power button to turn the DLS 355 ON and OFF. The unit will turn o automatically aer
15 minutes. To bypass auto-shuto, hold the power button for 5 seconds when turning ON.
5. 2 kHz Button
The 2 kHz button toggles the modulation of currently-selected wavelength output. The
laser flashes at 2000 times per second to provide a recognizable signal to a companion
power meter. Output power of the laser is reduced by 3 dB when the modulation is active.
6. Wavelength Button
The wavelength button switches between the 1310 nm and 1550 nm wavelength.
7. External Power Port
The port accepts the AC 030 power supply. The power supply is not a battery charger - just a
battery bypass.
Important Safety Information
WARNING!
Read and understand all of the instructions and safety information in this manual
before operating this tool.

LASER HAZARD
Please note that 1310 nm and 1550 nm wavelengths are not visible to the human eye. Do
not look directly into the output port of the DLS 355 or directly into any fiber connector
that may be live.
Since the laser is invisible to the eye, the eye’s natural blink reflex is suppressed. This
can cause damage to the retina.

IEC 60825-1: 2007-03
Class 1 Laser Product
Transmitting Light
The DLS 355 transmits either the 1310nm or 1550nm wavelength on single-mode fiber. It is
important to use a test jumper to mate the DLS 355 to the fiber under test.

Output Power
The DLS 355 is calibrated to have an output power level of -5 dBm. Variations in power level
between -5 dBm and -8 dBm may be normal depending on the quality and age of the test
jumper, the DLS 355 output port, and other factors.
Always ensure that the DLS 355 is transmitting an acceptable power level before performing
an insertion loss test. Simply insert the test jumper (plugged into the DLS 355) into a
companion power meter set to the dBm mode. The power meter will indicate the measured
output power of the laser.

Output Port Maintenance
The DLS 355 utilizes a physical fiber connection at the output port. It ensures a steady
power level for performing insertion loss tests.
Ensure that any test jumpers are inspected and cleaned before plugging into the DLS 355
unit. If soiled or damaged connectors are inserted, they can cause damage to the DLS 355
output port and the unit may need to be repaired.
The test jumper has physical contact with the
ferrule inside the DLS 355.

PAGE 4 M-UM007-03
TO CLEAN THE FERRULE INSIDE THE DLS 355:
• Unplug the test jumper
• Unscrew the adapter until it spins freely, then pull
• Inspect the ferrule with an approved microscope,
clean if necessary, and replace adapter
Using the 2 kHz Function
When the DLS 355's 2 kHz modulation is active, the selected wavelength indicator will
blink. The modulation is recognized by optical power meters further down the fiber and
indicated by a 2 kHz notification on the screen and a loud beep. The modulated tone can
also be recognized through the fiber jacket when a Live Fiber Identifier is used.
The LFI introduces a bend into the fiber which
leaks light from the core onto the detector of
the power meter. When using an LFI, expect a
30 to 35 dB oset in core power.
Testing Notes
Blue connectors (UPC) have a straight ferrule with a domed interface. Green connectors
(APC) have an eight-degree angled ferrule with a domed interface.
UPC and APC connectors are not compatible. NEVER connect UPC and APC connectors
together, OR plug an APC connector into the DLS 355 unit. This can cause irreparable
damage to both connectors.
Maintenance
Unpacking & Inspection
The DLS 355 is supplied with a so carry case, SC adapter installed on the unit, 3.0V CR2
battery, and an instruction card. Contact Ripley immediately if any part of the unit or
packaging is damaged, or otherwise unsatisfactory.
Low Battery
The DLS 355 provides over 1000 operations under normal conditions. When the LOW BAT
LED indicator is illuminated on the device, the CR2 battery should be replaced or recharged,
depending on the battery type.

M-UM007-03 PAGE 5
Optical Connector Interface
The DLS 355 is equipped with a SC/UPC connector adapter that is compatible with only SC/UPC
optical connectors. The connector adapter interface should be kept covered and protected
from contamination. Care must be taken to avoid objects that may damage the fiber inside the
adapter mount. Always inspect and clean fibers before mating them to the device. If scratches
or breaks occur on the fiber surface, please contact Ripley for proper service.
Calibration
All Ripley ODM® brand products include a 2-year warranty. Ripley recommends recalibration
every two years to ensure adherence to NIST measurement standards. The first recalibration
is free within the warranty period. Contact Ripley Tools for return information.
