QOTU Fiber
Labeling
Each Quad Optical Translator Unit (QOTU) spans two slots in the OT in odd/even
matched pairs. (25,26 or 3,4 for example). Each QOTU can contain up to four
Optical Translator Port Modules each with an input and output. The labeling
configuration for the fibers for the QOTU is illustrated in Figure 6-23.
NOTE:
The fiber to all OTPMs in a QOTU should be disconnected before the
carrier is engaged or disengaged from the backplane. It should also be
disconnected from the OTPMs when the OTPM is inserted into or removed
from the QOTU. All fibers should be disconnected if power is removed or
applied to the shelf itself.
