operating in half-duplex mode.

Table 6 100Base-FX Fiber Optic Ports (Half-duplex)

used inline within a single collision domain reduces the overall segment length by 40 meters (131 feet).

Selecting a Site

Be sure to observe the following guidelines when selecting a site for your

switch.

power to the device.

q Keep the twisted pair cabling away from sources of electrical noise,

such as radios, transmitters, power lines, broadband amplifiers,
