1x4 Optical Switch

1x4 Optical switch is a kind of functional component, with the ability to switch the optical route. In optical fiber transmission system, it is used for multi-channel fiber monitoring, multi-light source/ detector selection, and optical fiber path protection etc. Besides, it is also used in optical fiber test system for optical fiber and its component test, outdoor cable test and multi-spot optical sensors monitoring system.
