The AFL OLS4 are hand-held, integrated two-port light sources designed for performing insertion loss measurements on multimode or single-mode fiber optic links when used with an optical power meter. The LED and LASER outputs are stabilized to ensure accurate test results per current TIA/EIA requirements.

OLS4 Output Ports:
Multimode output port; 850/1300 nm LED output at CW, WaveID, or dual wavelength WaveID
Single-mode output port; 1310/1550 nm LASER output at CW, WaveID, dual wavelength WaveID, or 2 kHz Tone
Faster Test Times with WaveID - In WaveID mode, the OLS4 encodes each wavelength with a unique WaveID code. When used with a power meter, the pair can send and receive two wavelengths each test - doubling testing efficiency - reducing test time!

Flexible Output Connector Adapter Design
The OLS4 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, and LC connector adapters.

50 and 62.5 µm fiber mandrels included
Mandrels condition test cable for use in certifying both 50 and 62.5 µm fiber links for current and planned high bit rate applications including Gigabit Ethernet and 10 Gigabit Ethernet. Mandrels apply to launch jumpers in 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 multimode fiber 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 fiber size to the network fiber under test. AFL offers both 50 µm and 62.5 µm EF Mode Conditioners.
