buffer is 1Mbps to maintain high network performance. The MAC address memory is

8KB, suitable for medium to large networks.

In summary, the Magnum SPM-FDST is a multi-mode fiber optic switching

port module. It has 100Mb ST-type connectors. There are two LEDs, LINK and RX,

to allow monitoring of LINK and packet reception (Activity) status of the SPM. The

SPM may be used to connect to another full-duplex 100Mbps hub or switch using

fiber cabling and using the 100BASE-FX protocol. It filters and forwards packets in

both directions at Fast Ethernet wire speed.

Magnum SPM-FDSC

The Magnum SPM-FDSC is a multi-mode, full-

duplex fiber optic switching port module with a

100Mb SC-type connector. The module may be used

to connect to another 100Mbps hub or switch using

fiber cabling and the 100BASE-FX protocol. It filters

and forwards packets in both directions at Fast

Ethernet wire speed.

The operation and application of the SPM-

FDSC is the same as the SPM-FDST described

above, except for the connectors on the fiber cable.

2.5.3

Magnum SPM-FDSSC

The Magnum SPM-FDSSC is a single-mode, full-duplex fiber optic switching port

module with a 100Mb SC-type connector. The module may be used to connect to

another 100Mbps hub or switch using fiber cabling and

using the 100BASE-FX protocol. It filters and forwards

packets in both directions at Fast Ethernet wire speed.

Since the SPM module segments the network, it also

maintains its address tables to know what node

addresses are on which side of the unit.

The Magnum SPM-FDSSC includes full

switching functionality and has two LED’s -

LINK and RX - to allow monitoring of link and

activity status of the SPM. The Magnum SPM-

FDSSC is a full duplex module. Thus, two
