The Cisco SCE8000 Optical Bypass
Optical Bypass Module Specifications
Fiber Cable Type
The fiber cable type within the Optical Bypass Module area as follows:
• OPB-SCE8K-MM: 50 um core.
• OPB-SCE8K-SM: SMF-28
Maximum optical path (fiber length of two ports) is 600m.
Switching Time
Switching time is measured from trigger to stable 90% optical output.
• Typical switching time: 3 ms
• Maximal switching time: 10ms
Fan Assembly
The system fan assembly, located in the chassis, provides cooling air for the installed modules. Sensors
on the fan assembly and within the system monitor the internal air temperatures. If the air temperature
exceeds a preset threshold, the environmental monitor displays warning messages.
Figure 2-9 Fan Assembly
If an individual fan within the assembly fails, the FAN STATUS LED turns red. To replace a fan
assembly, see Removing and Replacing the Fan Assembly, page 9-11.
