Installing and Maintaining Uniboot Fiber Cables: Step-by-Step Guide

Posted on Sep 20, 2023 by

Uniboot patch cords are now used as the preferred fiber patch cords for high-density connections in data centers. They feature a reversed polarity single-boot design LC connector that eliminates the need for double zipper wires and reduces overall wiring by 50%. Therefore, understanding how the uniboot fiber patch achieves polarity reversal will give you a deeper understanding of its use. You can find out how in this article.

How to Reverse Polarity on Uniboot Cables?

It is well known that in traditional cabling systems using single fiber connectors, maintaining polarity requires the "B" transmit signal to be connected to the "A" receive signal. However, there are two types of duplex jumpers used to complete the serial duplex pair connection, depending on the polarity technique employed - the "A-to-B" jumper for straight-through cabling and the "A-to-A" jumper for crossover cabling. Therefore, polarity inversion is typically required during fiber cabling.

Here are several common steps for polarity conversion of uniboot connectors:

LC Flat Clip with Push-pull Boot

Polarity conversion method: Step 1:Unlock the latch from the back; Step 2:Rotate the plug frame body 180°; Step 3:Rotate the connector body 180°; Step 4:Re-attach boot to connector housing.

MDC DirectConec™ Uniboot

Polarity conversion method: Step 1:Unlock the latch from the back; Step 2:Rotate the connector body 180°; Step 3:Align the groove; Step 4:Re-attach boot to connector housing.

LC Flat Clip Uniboot

Polarity conversion method: Step 1:Align the groove; Step 2:Extract the clip; Step 3:Rotate the connector body 180°; Step 4:Re-attach the clip and lock it.

The operation of uniboot connector polarity conversion mentioned above can be more clearly understood through the following video to understand the specific usage methods and steps.

Cleaning and Troubleshooting Guidelines for Uniboot Fiber

In addition to the polarity conversion operation mentioned above, there are also some other aspects that need to be paid more attention to in the use and maintenance of Uniboot fibers. The following related operations on cleaning and troubleshooting Uniboot fibers hope to provide you with help.

Uniboot Patch Cord Fiber Cleaning

1. Prepare the necessary materials: detergent, cotton swab, or soft cloth.

2. Pour the detergent on a cotton swab or soft cloth, making sure the cloth or cotton swab is wet but not dripping.

3. Turn off the device and disconnect the power supply.

4. Gently wipe stains or dust on the Uniboot jumper with a damp cloth or cotton swab. Avoid using excessive force to avoid damaging the jumper.

5. During the wiping process, be careful not to let the cleaning agent enter other parts or interfaces to avoid failure.

6. After wiping, wipe the cleaner on the jumper with a clean cotton swab or soft cloth.

7. After making sure the jumper is completely dry, reconnect the power supply and turn on the device.

Basic Troubleshooting of Uniboot Fiber

When encountering signal loss, the following methods can be used to try to solve it: First, make sure that the Uniboot connector is installed safely and correctly at both ends of the cable. Second, check the connector or cable for any damage, such as bent pins or worn wires. Third, verify that the cable is compatible with the device you are connected to and meets the required specifications. Fourth, try connecting the device using a different Uniboot cable to see if the signal loss still exists.

If the Uniboot fiber is excessively bent or twisted, it will cause signal loss or connector damage, which will affect normal use. Therefore, special attention should be paid to the bending of the Uniboot fiber during use. Avoid the cable being tightly wrapped around other cables or objects, as this will cause interference and signal degradation. Alternatively, use cable management solutions such as cable clips or cable ties to properly organize and protect Uniboot cables.

During the use of Uniboot fiber, you may also encounter many problems with connectors. You can try the following methods for troubleshooting. First, check whether the Uniboot connector has any obvious damage, such as bent pins or loose connections. If any damage is found, consider replacing the connector. Secondly, make sure that both connectors are fully inserted and securely locked in their respective ports. In addition, you can also use a soft lint-free cloth to clean the connector according to the cleaning method mentioned above to remove any dirt or debris that may affect the connection. If possible, try using a different connector or replacing the connectors at both ends to check if the problem is specific to a specific connector.


The aforementioned actions are common methods to address polarity conversion and other issues with Uniboot. If you want to gain a better understanding of how to deal with these problems, it is recommended to carefully read the manufacturer's instructions or consult the equipment manual for guidance. Using proper tools and seeking help when needed will contribute to successfully resolving the issues.
