Inline topologies require connecting both Receive and Transmit fibers to the Cisco SCE8000 GBE.
Cascade ports always require both Receive and Transmit fibers to be connected.
To maintain link continuity at all times, optical bypass modules must be installed on both platforms and
the traffic ports must be connected to these bypass modules.
The Optical Bypass Module
The external optical bypass module is an optional component that provides additional protection by
enabling automatic preservation of the network traffic link. For more information regarding the external
bypass module, refer to
There are two installation options for the optical bypass module:

•
Make sure to use the correct type of optical bypass module (single-mode or multi-mode) according to
Note
the transceivers and cabling that are used for the subscriber and network links.
Since the optic bypass module will directly connect the subscriber and network side optic paths when
Note
bypassing the SCE8000 GBE, the subscriber and network optic links must be of the same type
(single-mode or multi-mode) and wavelength.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Avoid exposure to
radiation and do not stare into open aperture.
