What precautions should be taken when 1-to-4 optical jumpers are connected to ODFs

If 1-to-4 optical jumpers are routed to optical distribution frames (ODFs) and connected to four 10GE multimode optical fibers to transmit data over a certain distance, pay attention to the following points:

- Determine the fiber connector type (LC/FC) supported by the ODF and select appropriate optical jumpers for the supported connector type.
- Optical jumpers from the switches at both ends must be connected to the ODF at the same sequence.
- Each pair of TX and RX optical fibers must be cross-connected on the ODF to ensure normal transmission between the optical modules at both ends.

Description:
ODFs rarely support MPO optical jumpers. If the two switches are not far from each other, it is recommended that they be directly connected using MPO-MPO optical fibers.
