1.13.3 Breakout Box and Optical Fiber Maintenance
This section describes how to maintain the breakout box and optical fibers.
The maintenance method of the MPO and LC optical fibers applies to the mapping optical
fibers.
The maintenance method of the optical modules on the MPO and LC interfaces applies to
adapters on the breakout box.

The CR53CFE1 provides 24 E1/T1 interfaces. The connectors on the CR53CFE1 are of the
DB100 type, which cannot be directly used. Therefore, you need to use 100-ohm 24xE1 trunk
cables to connect the 24 E1 port conversion box and the CR53CFE1. In this manner, the
conversion box provides RJ48 interfaces and SMB interfaces that can be directly used. The
