AT-FS709FC Series Installation Guide
100 Mbps Fiber Optic Port
The AT-FS709FC Series switch features one fiber optic port. You can use the fiber optic port to connect the switch to another switch or other end node over large distances.
Type of Connector
The AT-FS709FC Series switches come with a variety of fiber optic connectors. Contact your Allied Telesyn International sales representative for a list of available connector types.
Speed
The fiber optic port is compliant with the 100Base-FX standard and has a fixed operating speed of 100 Mbps. This speed cannot be changed; the end node that you connect to the fiber optic port on the switch must also be able to operate at 100 Mbps.
Duplex Mode
The fiber optic port is able to operate in full-duplex mode only. The end node that you connect to this port must also be capable of full-duplex operation. For an explanation of duplex mode, refer to “Duplex Mode” on page 8.
Cabling
There are two basic types of fiber optic cabling used in Ethernet networks: multimode fiber and single-mode fiber. Multimode fiber is for shorter distances, typically not more than 2 kilometers (1.25 miles). Single-mode is for longer distances. The fiber optic port on the Ethernet switch has a maximum operating distance of 2 kilometers (1.25 miles) and is designed to be used with either 54/125 or 60/125 micron core/cladding multimode cable.
Note
Do not use single-mode fiber optic cable with the fiber optic port on the AT-FS709FC switch.
