Caution

For optical transceivers with a cabling distance of over 40 km/24.85 miles (including 40 km), install an
optical attenuator to avoid overload on the optical receiver when using short-distance single-mode fibers
(SMFs).

An optical transceiver is a laser transceiver. Do not look into the laser beam to avoid burning your eyes.

To keep an optical transceiver clean and dust-free, make sure that the unused ports remain capped.

Caution
BIDI optical transceivers must be used in pairs. For example, if GE-SFP-LX20-SM1550-BIDI is used at one
end, GE-SFP-LX20-SM1310-BIDI must be used at the other end.
