3.6 Cabling

Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must
be less than 100 meters (328 ft.) long.

Fiber segment using single-mode connector type must use9/125 µm single-mode
fiber cable. User can connect two devices in the distance up to 30km .

Fiber segment using multi-mode connector type must use 50 or 62.5/125 µm multi-
mode fiber cable. User can connect two devices up to 2km distances.

Gigabit / 100M SFP port:
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communications. The SFP slots
supporting Gigabit speed up to 1000Mbps.
–DSFP/-DFT models support dual speed
100M or 1000Mbps. They are used for connecting to the network segment with single
or multi-mode fiber. You can choose the appropriate SFP transceiver to plug into the
slots. Then use proper multi-mode or single-mode fiber according to the transceiver.
With fiber optic, it transmits at speed up to 1000 Mbps or dual speed (-DSFP/-DFT
models) and you can prevent noise interference from the system.
To connect the transceiver and LC cable, please follow the steps shown below:
First, insert the transceiver into the SFP module. Notice that the triangle mark is the
bottom of the module.
