JDSU
OLA-54
The JDSU OLA-54 is a portable tunable optical attenuator. The JDSU OLA-54 is calibrated for 850 nm and 1300 nm and uses multimode 50/125 µm fiber. The JDSU OLA-54 provides maximum attenuation of 60 dB, insertion loss of 2–2.5 dB, attenuation accuracy of 0.8 dB, and operates with powers up to +23 dBm.[1]
What it is
The JDSU OLA-54 is a portable tunable optical attenuator. The OLA-54 is designed for multimode fiber with a 50/125 µm core/cladding diameter. Calibrated wavelengths for the OLA-54 are 850 nm and 1300 nm. Maximum attenuation is 60 dB. Insertion loss is between 2 dB and 2.5 dB. Attenuation accuracy is 0.8 dB. The device can handle input optical power levels up to +23 dBm.[1]
