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 port, use an MPO-LC fiber to directly connect the optical module.

Figure 1 MPO-LC fiber structure

When using a breakout optical fiber, insert the X1 end into a 40GE QSFP+ optical module and the X2 end into four 10GE interfaces. If the 40GE interface is Down but the four 10GE interfaces are Up, check the 40GE interface status.

  • Check whether the 40GE interface supports the breakout function. If the 40GE interface does not support the breakout function, replace it with another interface that supports the breakout function.
  • Check whether the 40GE interface is in the breakout state. If the 40GE interface is not in the breakout state, configure the 40GE interface to be in the breakout state.
