General Inspection and Cleaning Procedures of Connectors

This section describes the connector cleaning process. Additional sections provide more detail on specific inspection and cleaning techniques.

General Cleaning Process

Complete these steps:

1.      Inspect the fiber connector, component, or bulkhead with a fiberscope.

2.      If the connector is dirty, clean it with a dry cleaning technique.

3.      Inspect the connector.

4.      If the connector is still dirty, repeat the dry cleaning technique.

5.      Inspect the connector.

6.      If the connector is still dirty, clean it with a wet cleaning technique followed immediately with a dry clean in order to ensure no residue is left on the endface.

Note: Wet cleaning is not recommended for bulkheads and receptacles. Damage to equipment can occur.

7.      Inspect the connector again.

8.      If the contaminate still cannot be removed, repeat the cleaning procedure until the endface is clean.


Figure 1 shows the connector cleaning process flow.

Note: Never use alcohol or wet cleaning without a way to ensure that it does not leave residue on the endface. It can cause equipment damage.


Connector Inspection Technique

This inspection technique is done with the use of fiberscopes in order to view the endface.

A fiberscope is a customized microscope used in order to inspect optical fiber components. The fiberscope should provide at least 200x total magnification. Specific adapters are needed to properly inspect the endface of most connector types, for example: 1.25 mm, 2.5 mm, or APC connectors.


Tools

 Clean, resealable container for the endcaps

 Fiberscope

 Bulkhead probe

Figure 2 shows different kinds of fibers-copes.

The bulkhead probe is a handheld fiberscope used in order to inspect connectors in a bulkhead, backplane, or receptacle port. It should provide at least 200x total magnification displayed on a video monitor. Handheld portable monitors are also available. Specific adapters are needed in order to properly inspect the endface of most connector types.

Caution: Read the reminders and warnings before you begin this process.
Complete these steps in order to inspect the connector:
1. Make sure that the lasers are turned off before you begin the inspection.

 Warning: Invisible laser radiation might be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.
2. Remove the protective cap and store it in a clean resealable container.
3. Verify the style of connector you inspect and put the appropriate inspection adapter or probe on your equipment.
4. Insert the fiber connector into the fiberscope adapter, and adjust the focus ring so that you see a clear endface image. Figure 5 shows a clean single mode connector endface.

5. Or, place the tip of the handheld probe into the bulkhead connector and adjust the focus.

Figure 6 shows the handheld probe inserted into a bulkhead connection.

6. On the video monitor, verify that there is no contamination present on the connector endface.

Tip: See the examples in Appendix B - Sample Images of Contamination Conditions for illustrations of different types of contamination.

7. Clean the endface and reinspect, as necessary. Refer to the appropriate section:

o Cleaning Techniques for Pigtails and Patch Cords

o Cleaning Techniques for Bulkheads and Receptacles

8. Immediately plug the clean connector into the mating clean connector in order to reduce the risk of re-contamination.

The Optical Fiber Interface Optical fiber interface is the physical interface used to connect optical fiber cable.The principle of optical fiber interface is the total reflection of using the light from the optically denser medium into optically thinner medium.Usually, the optical fiber interface is divided into SC, ST, FC and other types which are developed by Japan's NTT.FC is the abbreviation of Ferrule Connector. Its’ external strengthening way is to use a metal sleeve, and the fastening methods is turnbuckle. The ST interface is often used for 10Base-F. The SC interface is often used for 100Base-FX.

Reliability of Fiber Optic Patch Cord

Executive Summary  The quality, reliability, and performance of optical patch cords are assured by selecting the best components and by terminating and polishing with the best equipment and procedures.  These components and procedures must assure that the patch cords meet or exceed the requirements of all pertinent industry specifications.  This paper describes the relevance of the criteria in the applicable industry specifications, as well as the importance of the physical parameters and how they relate to the performance of the patch cord. Introduction   Fiber optic patch cords are one of the simplest elements in any optical network, consisting of a piece of fiber optic cable with

Review these reminders and warnings before you inspect and clean your fiber-optic connections

Reminders •  Always turn off any laser sources before you inspect fiber connectors, optical components, or bulkheads.•  Always make sure that the cable is disconnected at both ends or that the card or pluggable receiver is removed from the chassis.•  Always wear the appropriate safety glasses when required in your area. Be sure that any laser safety glasses meet federal and state regulations and are matched to the lasers used within your environment.•  Always inspect the connectors or adapters before you clean.•  Always inspect and clean the connectors before you make a connection.•  Always use the connector housing to plug or unplug a
