The Optical Bypass Module

The external optical bypass module is an optional component that provides additional protection by
enabling automatic preservation of the network 10 GBE link. For more information about the external
bypass module, see
There are two installation options for the optical bypass module:
•
•
Note Make sure to use the correct type of optical bypass module (single-mode or multi-mode) according to
the transceivers and cabling that are used for the subscriber and network links.
Because the optic bypass module will directly connect the subscriber and network side optic paths when

bypassing the Cisco SCE 8000, the subscriber and network optic links must be of the same type
(single-mode or multi-mode) and wavelength.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Avoid exposure to
