3.5 Connecting the Ethernet Interface (Fiber)
Prepare a proper SFP module and install it into the optical port. Then you can connect fiber optics cabling
that uses LC connectors or SC connectors (with the use of an optional SC-to-LC adapter) to the fiber optics
connector.
For a 100 Mbps fiber port available, please prepare the LC connectors or SC connectors (with the use of
an optional SC-to-LC adapter). They are also available with multimode, single mode, long-haul (for connections up to
120+ km) or special-application transceivers.
For a 1000 Mbps fiber port available, please use the mini-GBIC SFP (small form pluggable). These accept plug in
fiber transceivers that typically have an LC style connector. They are available with multimode, single mode, long-haul
(for connections up to 80+ km) or special-application transceivers.
For each fiber port there is a transmit (TX) and receive (RX) signal. Please make sure that the transmit (TX) port of
the switch connects to the receiver (RX) port of the other device, and the receive (RX) port of the switch connects to
the transmit (TX) port of the other device when making your fiber optic connections.
Refer to Table 1 for the normal operational LED status.

DANGER: Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical fiber and
putting the cover in position, as laser outputs will emit infrared laser light at this point.
