Sfp Expansion Slot - Allied Telesis AT-FS708/POE Installation Manual

SFP Expansion
Slot
Type of Cabling
For 10 Mbps operation, Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling is required. For 100 Mbps operation,
Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or
unshielded twisted pair cabling is required.
Auto MDI/MDI-X
All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab-
compatible. When a port's speed and duplex mode are set through Auto-
Negotiation, the port uses the auto-MDI feature to automatically configure
itself as MDI or MDI-X when connected to an end-node. Consequently,
you can use either a straight-through or crossover twisted pair cable when
connecting any network device to a port.
The AT-FS708/POE switch has one SFP expansion slot that can
accommodate one optional Small Form-factor Pluggable (SFP)
transceiver module, also referred to as a mini-GBIC.
The SFP modules are a fast and easy way for you to add an 1000 Mbps
fiber optic port to your Fast Ethernet switch. You can use the modules to
extend the distance of your network, build a high-speed backbone network
between switches, or connection additional end nodes to the network,
such as high-speed servers.
Figure 3 shows an example of a fiber optic SFP transceiver module.

Note
The SFP module only supports Gigabit operation and it works
independently without taking any port priority.
