RJ45 Cable
Distance
The maximum cable length for 10/100/1000BaseT is typically 100 meters (328 ft.).
Gig SFP
Ports 9-12
Ports 9 -12 are gigabit ports that provide SFP (Small Form-factor Pluggable) connectors. This
allows you to use the RJ45 connectors for twisted pair copper connections or use the SFP
connectors for fiber optic connections. The SFP connectors support 100 Mbps and 1000 Mbps
fiber optic transceivers for links up to 120 Km.
Note: For ports 9 and 10 you can only use one of the connectors (RJ45 or SFP) at a time. If
you connect to both at the same time then neither connector may work.
Fast SFP
Ports 1-8
Ports 1 through 8 offer flexible SFP (Small Form-factor Pluggable) connectors that support
10/100 Mbps RJ45 copper or 100 Mbps fiber optic SFP transceivers. On these 8 ports you can
mix and match copper and fiber as desired.
Typical SFP Transceivers
The SFP transceivers just plug into the SFP cages. To lock them in place lift the locking arm
as shown in the image above. To remove a transceiver, first pull down on the locking/release
arm and then pull the transceiver out.
The transceivers are “hot-swappable” meaning they can
be plugged in or removed when the switch is powered.
Fiber Wiring
Guidelines
The SFP ports accept fiber optic SFP transceivers. These transceivers are sold separately and
are available as multimode, singlemode, long-haul (up to 120 Km or more), BiDi (bidirectional),
WDM and other special types. They typically are offered with an LC style fiber connector.
Refer to the datasheets for these transceivers for more details.
