Optical Bypass Module (OPB-SCE8K)
Optical Bypass Module Connectivity
The optical bypass module functions as follows:
• Under normal conditions, the bypass module directs traffic to flow via the Cisco SCE 8000. (See
Figure 2-7.)
• Under failure conditions, the optical bypass shortcuts the interfaces that are connected to the traffic
link, and all traffic flows through the optical bypass module, bypassing the SCE platform. (See
Figure 2-7.)

Optical Bypass Module (OPB-SCE8K)
There are two types of optical bypass modules to support different optic types:
• OPB-SCE8K-SM supports Single-Mode optics and should be used with Cisco SCE 8000 equipped
with Single-Mode optics.
• OPB-SCE8K-MM supports Multi-Mode optics and should be used with Cisco SCE 8000 equipped
with Multi-Mode optics.
The optical bypass module is installed either internally, in slot #4 of the Cisco SCE 8000 chassis or in
an external mounting panel in the rack.
Up to two optical bypass modules can be mounted internally, supporting inline insertion into two links.
