Three Kinds of Polarity Reversal Methods of LC Uniboot Patch Cords


As the networking environment of today becomes increasingly dependent on high-speed and high-density solutions, effective cable management is a real problem. The challenge is how to manage more cables in a smaller amount of space. The LC uniboot patch cord utilises a special “round duplex” cable that allows duplex transmission within a single 2.4mm or 3.0mm cable, which reduces cable management space by up to 70% comparing to standard LC patch cords. Besides, it has a unique polarity reversal design allows the fiber polarity to be easily switched without the use of any tools. In today’s LC uniboot patch cords market, there are usually three methods to reverse the polarity.

Method One
1. Open connector top.

2. Switch the polarity.

3. Close connector top.


Method Two
1. Locate trigger housing on LC uniboot connector and pull towards the boot.

2. Open trigger housing is resting on the boot turn each LC connector to the outside 180 degrees one at a time.

3. Complete the polarity reversal by turning the resting trigger housing 180 degrees around boot and click into LC until you hear a click.


Method Three
1. Connector Polarity
Uncrossed lines under the connector latch on the housing at both ends indicates uncrossed fiber polarity A-B/B-A.

2. Unlock Front Housing on One End
Push the keys on either side to unlock the housing to remove the front section of the Uniboot housing.


3. Remove Front Housing
Slide the front housing away from the rest of the Uniboot.

4. Rotate Front Housing
Flip the released section of the housing. Do not rotate or twist the fiber.

5. Attach Front Housing
Push the housing back over the ends and the rest of the Uniboot connector until it clicks back into place.

6. Connector Polarity
Finished result should now show crossed lines under the flipped connector latch and uncrossed lines on the unaltered end. This would indicate a crossed fiber polarity A-A/B-B.


Different kind of LC uniboot patch cords may have different polarity reversal design, therefore we must use different method to change the polarity. When you choose to use LC uniboot patch cords in your network, keep in mind to take the polarity reversal methods in to consideration. FS.COM LC uniboot patch cords (easily reverse the polarity with method one) terminated with premium grade zirconia ceramic ferrule connectors which help assure high transmission quality and low optical power loss and offer improved airflow and visibility of equipment within a high-density network environment.

Data Center Patch Cords Organized


The benefit of having neat and organized cabling obviously applies to patch cords as much as structured cabling. When you go beyond green considerations, it can be argued that it’s more important to have neat patch cords than structured cabling. Data Center users typically interact with a patching field when installing or servicing hardware rather than structured cabling. Patching fields can be more challenging to maintain in some server environments, however, due to frequent hardware changes and sometimes minimal management of how patches are run.

You can follow several strategies to keep Data Center patch cords organized, thereby improving airflow to equipment, reducing energy consumption of your cooling infrastructure, and easing troubleshooting. (Not to mention maintaining the professional appearance of your Data Center.)

■ Employ a distributed cabling hierarchy: Already mentioned as beneficial for structured cabling, this approach can help with Fiber Optic Patch Cables as well. Having Data Center networking patch fields divided into smaller segments around the Data Center mitigates cabling density and potentially improves airflow to the associated networking equipment.
■ Right-size port counts: Planning the correct number of ports in your Data Center – and reserving space for future expansion of patch fields – helps avoid messy cabling. Installing too many ports can result in unnecessarily large cable bundles; installing too few can trigger picemeal cabling additions in the future that fit awkwardly with the original cabling infrastructure.
■ Use ample wire management: However many connections you install in your network patching fields, be sure to include sufficient vertical and horizontal wire management to handle the maximum quantity of patch cords you plan for. This is of particular importance for some Category 6A patch cords because of their increased outsied cable diameters and soild copper core wire construction. This type of cord promotes a cable memory that can be increasingly difficult to manage as the number of patch cords multiply.
■ Prepatch networking connections: Hardware density in modern Data Centers can involve thousands of cable connections in a single server row. Prepatching networking devices and patch fields all together, before servers are installed, helps ensure that cabling is routed neatly.
■ Provide patch cords in different length – and use them: Stock commonly used types of patch cords in your Data Center in multiple lengths so that whoeer install your hardware can make a neat connection between devices and patching fields. That means correctly routing cabling through the available wire management rather than making a straight-line connection that blocks access to hardware or patch panels. It also means choosing the right length of cable length, so there is no slack to be either coiled up and hidden in the wire management system or left hanging at the end of a connection.

Implementing these cabling practices, first when designing a new Data Center and then when operating, doesn’t just make the facility greener by improving airlow and conserving cabling material, it also makes it easier to use and less prone to accidental down-time.
