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. If properly maintained and cleaned, this connector can

withstand many repeated connections.

However, many instrument specifications require tighter tolerances than most

connectors, including the FC/PC style, can deliver. These instruments cannot

tolerate connectors with the large non-concentricities of the fiber common

with ceramic style ferrules. When tighter alignment is required, Agilent

Technologies instruments typically use a connector such as the Diamond

HMS-10, which has concentric tolerances within a few tenths of a micron. Agi-

lent Technologies then uses a special universal adapter, which allows other

cable types to mate with this precision connector. See Figure 3-2.
