Optical Bypass Module Specifications
This section describes the following:
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 600 m.
Switching Time
Switching time is measured from trigger to stable 90% optical output.
• Typical switching time: 3 ms
• Maximal switching time: 10 ms
Fan Assembly
The system fan assembly, located in the chassis, provides cooling air for the installed modules (See
Figure 2-9). 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” section on page 9-13.
