The VIAVI Solutions OLA-15 is a handheld optical attenuator for precise control of optical signal power in single-mode fiber systems. It enables laboratory and field testing through continuous attenuation adjustment across a 3 dB to 60 dB range with 0.05 dB resolution. The instrument simulates line loss for BER testing, determines receiver sensitivity and system margin, and calibrates optical power meters across the 1260 to 1625 nm window.
