1.13.1 Breakout Fibers
This section describes the positioning, usage scenario, structure, and technical specifications
of breakout fibers.
Positioning
Breakout fibers are used to flexibly allocate bandwidth resources to routers. They cooperate
with a breakout optical module to convert an MPO interface into multiple LC interfaces to
facilitate fiber layout.
Usage Scenario
The breakout function applies to a scenario where bandwidth resources are unevenly allocated
between two routers at different levels. In comparison with breakout boxes, breakout fibers
implement the following functions:
Loosen fiber layout.
Extend the cabling distance.
Fiber Structure
To insert a breakout optical module (multimode and short transmission distance) into a board,
use an MPO-LC fiber to directly connect the board and the optical module.
