Let's talk about the different styles of LC connectors and their specific features and benefits. Here’s a standard LC jumper. It’s built on duplex zip cord, has a clip, it’s not removable, and the push mechanism offers a secure connection.
This assembly is virtually the same; however, it has a side release clip. This can allow for polarity changes in the field. Changing polarity in the field is a Band-Aid® fix. You should always choose and follow a polarity standard; however, in a pinch, this could really get you out of a jam.
The most modern assemblies are built with single-body Uniboot connectors and 2.8-millimeter round cordage. These features offer a myriad of benefits, but most importantly, the round cordage offers a 30-percent reduction in cabling bulk and is much easier to manage.
