Dual Wavelength LED Source

NOYES OLS1-Dual is a hand-held, rugged LED light source designed for performing insertion loss measurements on multimode fibre optic links when used with an optical power meter. The LED output is stabilised to ensure accurate test results per current TIA/EIA requirements.

Multimode Output Port; emits 850/1300 nm LED output at CW, WaveID, or dual wavelength WaveID.

Faster Test Times with WaveID – In WaveID mode, the NOYES OLS4 encodes each wavelength with a unique WaveID code.  When used with a NOYES power meter, the pair can send and receive two wavelengths each test – doubling testing efficiency – reducing test time!

Flexible Output Connector Adapter Design

The OLS1-Dual output ports are equipped with UCI based removable adapters to allow the output connectors to be inspected and cleaned, while allowing field change of output style between FC, SC, ST, & LC connector adapters.

50 and 62.5 µm fibre mandrels Included

Mandrels condition test cable for use in certifying both 50 and 62.5 µm fibre links for current and planned high bit rate applications including Gigabit Ethernet and 10 Gigabit Ethernet.  Mandrels apply to launch jumpers is seconds without tools and ensure loss measurements comply with TIA/EIA-568-B standard.

Encircled Flux Compliance

International standards bodies established Encircled Flux (EF) guidelines (TIA-568-14-B and IEC 61280-1-4) to improve measurement repeatability by reducing loss measurement variation to within a target range of ± 10%.

EF Mode Conditioners attach to the output of your multimode source ensuring the "conditioned output" meets Encircled Flux specifications.  Compliance requires matching the output fibre size to the network fibre under test. AFL offers both 50 µm and 62.5 µm EF Mode Conditioners.  See below for list of fibre and connector combinations available.
