Title
Fiber Optic Connector Endface Cleaning System Evaluation
Telecommunications Industry Association
Publication Date:
Sep 1, 2009
Scope:
INTRODUCTION
Intent
The intent of this document is to provide a standard means for
evaluation of systems designed to remove contamination from fiber
optic connector endfaces. This procedure is applicable to all
single and multi-fiber connector types populated with any fiber
type.
Contamination trapped between mating optical connector endfaces
can result in the following failure modes:
• Increase in attenuation
• Increase in return loss
• Permanent polished endface damage due to abrasion
• Permanent polished endface damage due to contamination
response during higher power throughput applications
It is beyond the scope of this document to define or specify
cleaning systems. This document is applicable to both In-situ
(bulkhead) and free connector cleaning systems.
Forms of Contamination
This document addresses some of the most common forms of
contamination observed in indoor and outdoor optical data
transmission systems.
Oil
Oil which typically is a result of direct contact with human
skin is simulated by an all purpose vegetable oil extracted from
corn, soybeans, peanuts, cottonseeds, safflower seeds, rape seeds
and sunflower seeds.
Solvent Residue
Isopropyl alcohol is a commonly used cleaning fluid for optical
connectors cleaning and is used to generate solvent residue on the
connector endface.
Mineral Deposits
A saturated solution of water and sodium chloride is used to
generate a mineral deposit residue on the connector endface.
Dust
Airborne particulate matter simulated by ISO Fine Test Dust
12103-1 A2 (Test dust for filter evaluation; Arizona Road Dust).
Cleaning performance on particulate matter is evaluated with and
without the connector specimens having been mated.
