Figure 2.6 – Gigabit Combo Ports
The following figures show the cabling schematics for straight-through and crossover.
2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ-45 port connections. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100
meters (328 ft.) in length.
2.7.1 Gigabit Combo Port - Copper/SFP (Mini-GBIC)
Antaira Technologies’ LMP-1002C-SFP series has two auto-detected Gigabit combo ports
(2*10/100/1000Tx RJ45 and 2*100/1000 SFP
slots for fiber connection) shown in Figure 2.6.
The Gigabit copper (10/100/1000T)
ports should use category 5e or the
above UTP/STP cable for the
connection up to 1000Mbps. The small
form-factor pluggable (SFP) is a
compact optical transceiver used in
optical communications for both
telecommunication and data
communications.
The SFP slots support dual rate mode,
which can switch the connection speed
between 100 and 1000Mbps. They are used for connecting to the network segment with
a single or multi-mode fiber. Users must first choose the appropriate SFP transceiver to
plug into the slots, and then choose the proper multi-mode or single-mode fiber according
to the transceiver being used. When fiber optic is used, it transmits at a speed up to 1000
Mbps and it can prevent noise interference from the system.
