Optical connector
For the transmission cables of the Active Star Coupler, the optical fiber cables (cords) are
used.
(1)
Position and name of optical connector
The Active Star Coupler has ten optical connector connection ports, CH1 through CH10.
They are positioned on the front panel of the unit: CH1 and CH10 are FC Type connectors, and
CH2 through CH9 are F07 Type connectors.

Connection of cables
Connection is made between FC Type connector and FC Type connector, and between
F07 Type connector and F07 Type connector.
For more detail, refer to "9. Installation and wiring".
(Note) Sinse all ports have no priority among them, arbitrary one may be used. Nevertheless,
when the daisy-chain connection between ASC25s is done, use CH1 and CH10 (FC
Type). (Although CH2 through CH9 can establish the daisy-chain connection between
ASC25s without raising functional problems, the FC Type connector has a function of
preventive means to single-wire breaking and is able to function the preventive means to
single-wire breaking between ASC25s, so that we recommend the use of CH1 and CH10.
