Product Overview
JDS Uniphase manual variable precision attenuators provide precise, repeatable, and manual control of light levels for field system testing as well as for test and development in laboratory applications. Both series use micrometer control for high-resolution attenuation of 50-70 dB with calibration wavelengths of 830, 1300, or 1550 nm.
Using ultra-linear attenuator prism and highly reliable microlense technology, they provide highly accurate, continuously variable attenuation with low insertion loss and an excellent return loss of > 60 dB. Each model is available in both single-mode and multimode versions. Singlemode models are available with an analog option and feature > 60 dB return loss and low spectral ripple for CATV AM systems.
The attenuators are battery-powered for portability and convenient use in the field when high precision is required. The VA5B attenuator features 3 mm cable pigtails that are supplied bare or with the customer's choice of connector type. The VA6B attenuator features a panel-mounted PC or APC universal connector adapter (UCA), which supports FC/PC, SC/PC, and ST/PC or FC/APC and SC/APC connector types.
