Connectors also vary in the polish, curve, and concentricity of the core within the cladding. Mating one style of cable to another requires an adapter. Agilent Technologies offers adapters for most instruments to allow testing with many different cables. - Page 38 Reference Cleaning Connections for Accurate Measurements Figure 3-1. Basic components of a connector. Over the last few years, the FC/PC style connector has emerged as the most popular connector for fiber-optic applications. While not the highest perform- ing connector, it represents a good compromise between performance, reli- ability, and cost.
- Page 39 0.2 µm. This process, plus the keyed axis, allows very precise core-to-core alignments. This connector is found on most Agilent Technologies lightwave instruments. The soft core, while allowing precise centering, is also the chief liability of the connector.
- Page 40 Reference Cleaning Connections for Accurate Measurements Inspecting Connectors Because fiber-optic connectors are susceptible to damage that is not immedi- ately obvious to the naked eye, bad measurements can be made without the user even being aware of a connector problem. Although microscopic exami- nation and return loss measurements are the best way to ensure good connec- tions, they are not always practical.

Damage from improper cleaning. While these often work well on first insertion, they are great dirt magnets. The oil or gel grabs and holds grit that is then ground into the end of the fiber.
- Page 42 Reference Cleaning Connections for Accurate Measurements nectors, using small glass spheres. When used with contacting connectors, these glass balls can scratch and pit the fiber. If an index matching gel or oil must be used, apply it to a freshly cleaned connector, make the measurement, and then immediately clean it off.
- Page 43 Cleaning Connectors The procedures in this section provide the proper steps for cleaning fiber- optic cables and Agilent Technologies universal adapters. The initial cleaning, using the alcohol as a solvent, gently removes any grit and oil. If a caked-on layer of material is still present, (this can happen if the beryllium-copper sides of the ferrule retainer get scraped and deposited on the end of the fiber during insertion of the cable), a second cleaning should be performed.
- Page 44 Cleaning Connections for Accurate Measurements C A U T I O N Agilent Technologies strongly recommends that index matching compounds not be applied to their instruments and accessories. Some compounds, such as gels, may be difficult to remove and can contain damaging particulates. If you think the use of such compounds is necessary, refer to the compound manufacturer for information on application and cleaning procedures.

- Page 46 To clean an adapter The fiber-optic input and output connectors on many Agilent Technologies instruments employ a universal adapter such as those shown in the following picture. These adapters allow you to connect the instrument to different types of fiber-optic cables.
- Page 47 Reference Cleaning Connections for Accurate Measurements 3 Dry the inside of the adapter with a clean, dry, foam swab. 4 Blow through the adapter using filtered, dry, compressed air. Nitrogen gas or compressed dust remover can also be used. Do not shake, tip, or invert compressed air canisters, because this releases particles in the can into the air.
