l Overview
Cable Capacity
The number of cables that can be stored in the FMT/1HU depends on the cable
dimensions and lengths. The following table provides maximum recommended values
based on the dimension and length of the cable. The maximum cable number can only be
stored in the shelf when the cables are guided carefully in parallel without crossing and is
applicable to each side (incoming and outgoing) of the FMT/1HU.

Table 60: Recommended Values for the Capacity of the FMT/1HU
Considering all cable dimensions, a minimum length of 45 cm (17.717 in.) of fiber can be
stored in the FMT/1HU when it is laid directly from one sliding radius limiter to the other.
