1) Universal Connector Interface
The universal connector interface included with the DLS accepts many connector types including FC, SC, ST and LC.
The screw on style connector provides easy switching to hybrid adapters to accommodate various connector
styles. Please contact ODM for available connector styles and patch cords.
2) Power Key
To power the DLS press the PWR button. To turn the DLS off, press
PWR button again. The DLS is set to turn off after 15 minutes. For continuous operation
press and hold the PWR button for three seconds or power on.
3) λ Wavelength Select
Press the λ button to toggle between 850nm and 1300nm for the
DLS 350 or 1310nm and 1550nm for the DLS 355.DLS 350 & DLS 355 Operation & Service
4) λ Wavelength Indicator
The wavelength indicator will be on, signifying that power is on and wavelength selected.
5) Low Battery Indicator
Low Battery condition exists when the LOW BATT LED flashes.
The DLS operates from a long life CR2, 3V Lithium Battery.

6) 2kHz Mode
To modulate the DLS @ 2kHz press the 2kHz button.
7) External Power Port
External power port accepts a 120 volt or 240 volt AC Adapter. Please see Accessories section for available AC
Adapters.
2.2 Usage Instructions
The DLS 350 and DLS355 are used in conjunction with the RP 400 series power meters providing loss measurements
according to EIA/TIA standards.
The DLS 350/DLS 355 dual light sources also provide a 2kHz tone output for fiber identification when used with the RP
400 series power meters. The incoming 2kHz signal is identified and an audible alert is provided by the RP 400 series
power meter. The 2 kHz tone provided by the DLS 350 and 355 may also be used with non invasive fiber identifier
devices such as the LFI 110 Live Fiber Identifier from ODM.
Connection to the device under test (DUT) is by the universal connector output allowing for easy cleaning of the
connector surface. Please contact ODM for hybrid adapters to accommodate different connector styles. See Accessories
section for available hybrid adapters. These dual sources are provided with a long lasting battery or may be factory
configured for optional AC operation.
