Today we are going to talk about re-deploying fiber assemblies. So, let's get right to it.

Can I Re-use Fiber Assemblies?

The short answer is yes. However, there are some very critical aspects before you do this.

The first thing you want to do is make sure nobody has been jump roping with the fiber assemby. (Just seeing if you are awake.)

Endface Inspection

One of the first things you want to do is endface inspection.  Why?  If you deploy fiber that is contaminated the contamination will spread to whatever you are connecting to. This can cause some very troublesome issues.  See episode #23 - Fiber Optic End Face Contamination for more on this topic.

Fiber Damage

The next concern is fiber damage.  Your cable could be kinked or bent. The best way to check this is to measure the insertion loss with a power meter.  Most end users do not have this capability.  But it is the only way to ensure there is going to be enough signal strength  for the data to be transmitted properly.

Fiber Protrusion

Another worry could be fiber protrusion.  This should not be a concern if you purchase from a manufacturer that has a good, thorough quality control process.  If you don't, you will be needlessly putting yourself at risk.

Fiber protrudes from the endface a certain amount. It is critical that it is to a very specific measurement range. This needs to me constantly monitored on the manufacturing line.

What happens if there is too much protrusion? 

Bad news, that's what. If there's too much protrusion the fibers can mate up and then crack. So, a known working cable can crack.  That can lead to DOWN TIME. And nobody wants that.

So, What Is The Verdict?

Ponder all of these factors against your requirements, capabilities, and downtime costs when considering whether or not to re-use fiber assemblies. Consider buying some newfiber assemblies  instead.  With new fiber assemblies you can ensure you have bend insensitve fiber and higher bandwidth capabilities.
