STAR-20 Star Coupler
Star coupler with 5 or 6 optical inputs for reliable connection of distributed equipment.
The STAR-20 star coupler is intended for star topology optical connection of distributed equipment to a central unit. It supports two operating modes: routing six optical inputs to an RS485/RS232C line or routing five optical channels CH1-CH5 to channel CH0.
