GEZHI Photonics 1x8 Mechanical Optical Switch connects optical channels by redirecting an incoming optical signal into a selected output fiber.
GEZHI 1x8 Mechanical Optical Switch support all wavelength at 1260nm~1650nm, it offers ultra-high reliability, low insertion loss, fast switching speed as well as bi-directional performance. The optical switches are widely used for Optical Network, Protection, Transmitter and Receiver Protection,Network Test System and Instrumentations.
GEZHI 1×N Optical switch is a kind of functional component, with the ability of switching 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.
