The 81594B 2x2 Optical Switch Module is one of the modular optical switches family of plug-in modules for Lightwave Solution Platforms 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 environments.
