Sfp Port - TP-Link TL-SG3109 Installation Manual

TL-SG3109/TL-SL3428/TL-SL3452
the switch automatically ascertains the maximum speed (10 or 100 or 1000
Mbps) and duplex mode (half- or full-duplex) of the attached device. All ports
support only unshielded twisted-pair (UTP) cable terminated with an 8-pin
RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto
Uplink. This technology allows attaching devices to the RJ-45 ports with either
straight-through or crossover cables. When inserting a cable into the switch's
RJ-45 port, the switch automatically:
Senses whether the cable is a straight-through or crossover cable.

Determines whether the link to the attached device requires a "normal"

connection (such as when connecting the port to a PC) or an "uplink"
connection (such as when connecting the port to a router, switch, or hub).
Configures the RJ-45 port to enable communications with the attached

device, without requiring user intervention. In this way, the Auto Uplink
technology compensates for setting uplink connections, while eliminating
concern about whether to use crossover or straight-through cables when
attaching devices.

2.6.2 SFP Port

The GBIC module bays accommodate standard SFP GBIC modules, such as
the TL-SM311LM or TL-SM311LS from TP-LINK, allowing fiber connections
on the network.
The SFP GBIC bay accommodates a standard SFP GBIC module. Small
Form Factor Pluggable (SFP) Optical Transceivers are integrated duplex data
links for bi-directional communication over multimode optical fiber, designed
for high-speed Fibre Channel data links. The SFP port is designated as
1000Base-FX.
