The optical transmission module of the multi-transverse mode needs to be connected to the multi-mode fiber. The optical transmitting module of the single-longitudinal mode or multi-longitudinal mode needs to be connected to the single-mode fiber.

The connectors at both ends are LC/PC-LC/PC, LC/PC-FC/PC, or FC/PC-SC/PC single-mode fibers. Multi-core fibers (each with a total of eight cores that can be split into single fibers) can be used on NE40Es to increase the fiber placement efficiency.

Figure 3-37 shows the appearance of multi-core fibers.

Figure 3-37 Appearance of a multi-core fiber

When using multi-core fibers, pay attention to the following points:

  • Split each multi-core fiber inside the cabinet into different single-core fibers at the cable inlet.
  • When splitting a multi-core fiber, hold both sides of the fiber with your hands and gradually tear the fiber with force. Do not over-bend the fiber or tear the fiber from any intermediate core.

  • The eight fibers split from the same multi-core fiber can be installed on different boards. However, installing the eight fibers in both the upper and lower chassis in the same cabinet is not recommended.
