6.6Optical 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.

(2)Connection cable

∙for FC Type: (CH1 and CH10)

Optical fiber cable: Silica Glass GI optical fiber cable (core diameter 50 μm, clad

diameter 125μm)

∙for F07 Type: (CH2 through CH9)

Optical fiber cable: H-PCF (hard clad Silica Glass SI optical fiber cable (core

diameter 200 μm, clad diameter 230μm)

(3)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.
