Agilent 81591B modular optical switches are a family of plug-in
modules for Agilent Lightwave Solution Platform 8163A/B,
8164A/B and 8166A/B. They enable manufacturers of optical and
network components to automate their processes by routing optical
signals when testing devices such as line cards, amplifiers, and
active and passive components. Adding modular optical switches to
this instrument platform allows flexible and cost effective all-in-one
solutions to be developed for optical component test in automated
test environment.
