1×18 TTL SM MM 850/1310/1550 optical fiber switch for protection High Reliability
OSW1×18 TTL optical fiber switch
Introduction of OSW 1*18 optical fiber switch
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.
Product Features of TTL optical switch
·Low Loss and High Reliability
·Parallel Interface (TTL)
·Modularized Design
·Epoxy-free on Optical Path
