TOSLINE-S20 Active Star Coupler (ASC25) Instruction Manual 6F3B0360

2.Overview

The Active Star Coupler is used for distributing fiber optic signals in a TOSLINE-S20 network.

The TOSLINE-S20 is a Bus-style transmission system. If the power is off in one of the stations on this bus, communication is not possible before or after that station.

To prevent this from happening, an Active Star Coupler can be used.

If the Active Star Coupler is used, a station that is off will have no effect on the rest of the transmission system. The Optical Connector Board of the Active Star Coupler has ten ports (CH1 through CH10), in which CH1 and CH10 adopt FC Type connector same to the general version of Active Star Coupler (ASC22). Other ports, CH2 through CH9, adopt the JIS-F07 Type connectors which are mounted to TOSVERT-μ/S250W/W drive station, etc.

Appearance of the Active Star Coupler is shown below.
