Precautions for the use of MPO fiber patch cords


The research and development and application of MPO fiber optic connectors in practical engineering play an important role and significance. It greatly improves the popularity of optical networks and reduces costs. It is a very important application in optical fiber communication networks, transmission systems and CATV networks. At the same time, the application of MPO fiber jumper high-density wiring in practical engineering has an important role and significance. The use of MPO fiber jumper is a very particular knowledge and skill, and it is also a very important link.

Possible problems with MPO fiber patch cords

1. Guide pin hole damage

The main reason is that the insertion direction of the male head is inclined when the connection is made, and the front end of the guide pin of the male head is scratched and scratched. Such damage can directly cause some or all of the channel loss values ​​to increase.

2. The end face is dirty

It is mainly caused by prematurely removing the dust cap before docking or exposing it to a non-clean environment for a long time. Such contamination will directly affect the docking performance of the product, making the docking effect unstable, and even causing damage to the opposite connector during docking.


3. Mechanical damage of parts

It is mainly caused by the excessive application of external force during the construction process. Such damage may not affect the performance in the initial stage, but it will basically fail completely in the short term.


4. Cable mechanical damage

If it is mainly caused by dragging or unintentional cutting during construction, such damage may not affect the performance in the initial stage, but it will basically fail completely in the short term.


In order to avoid the above damage and improve the wiring connection rate and long-term stability, the following points should be paid attention to during the wiring process:


Try to avoid opening the dust cap before connecting the optical fiber jumper.


Try not to remove the dust cap from the adapter interface that has been connected to the adapter panel but has not been docked.


Except for normal mating, do not allow the ground end of the connector to come into contact with or scratch any other objects.


If there is foreseeable dirt on the end surface, try to use special cleaning tools or clean paper soaked with absolute ethanol to clean the end surface. Do not use paper towels, cotton wool, ordinary cotton swabs, etc.


When docking the connector, confirm that the connector positioning key direction is extended to the adapter or the socket panel is inserted axially, and it is not allowed to repeatedly insert and pull out without being able to view the end face.


When inserting the MPO connector into the adapter, pay attention to the part of the connector boot, and when pulling it out, hold the part of the connector shell.


When bending the cable, keep the bending radius equal to or greater than 20 times the outer diameter of the cable.


When bundling cables, keep the tightness appropriate, and the cable sheath must not be severely deformed.


When perforating the cable and threading the tube, use the method of pushing and pulling. Do not drag or push the cable vigorously to prevent the cable from being broken or broken due to scratches.
