hazardous radiation exposure. Statement 1057
For supported X2 transceiver media types, refer to:

Because of interoperability issues, Cisco does not support X2s purchased from third-party vendors.
Caution
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard.
However, their higher optical quality allows them to reach 10 km over SMF cable instead of the 5 km
specified in the standard.
If an LR X2 designed for operation on an SMF cable is directly coupled to an MMF cable, an effect
known as Differential Mode Delay (DMD) might occur. See the Catalyst 4000 Family Module
Installation Guide for more information.

Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the
transceiver optical bores until you are ready to make a connection.
Always inspect and clean the SC connector end-faces just before making any connections. Refer to
the Tip on page 23 for a pointer to a fiber-optic inspection and cleaning white paper.
Always grasp the SC connector housing to plug or unplug a fiber-optic cable.
