2.4 Optional SFP Fiber Transceiver Modules
Ports 25. 26 on the LGB1005A include two types of media: twisted-pair (TP) and optional small form factor
pluggable (SFP) fiber (LC, BiDi LC, etc.) modules. The twisted-pair ports are the switch’s two rightmost RJ-45
twisted-pair connectors (ports 25, 26). For the fiber option, 1000-Mbps fiber transceiver modules slide into the
switch’s two fiber module slots (located to the right of the twisted-pair connectors on the switch’s front panel).
The fiber transceiver modules are used for high-speed connection expansion. The two fiber ports auto detect
10/100/1000-Mbps TP or 1000-Mbps SFP fiber.
Five 1000-Mbps transceiver modules are available. These modules are described below and shown in Figures 2-3
and 2-4.
