Figure 2-4. Universal adapters to Diamond HMS-10.
The HMS- 10 encases the fiber within a soft nickel silver (Cu/Ni/Zn)
center which is surrounded by a tough tungsten carbide casing, as
shown in
Figure 2- 5 .
Figure 2-5. Cross-section of the Diamond HMS-10 connector.
The nickel silver allows an active centering p rocess that p ermits the
glass fiber to be moved to the desired p osition. This p rocess first
stakes the soft nickel silver to fix the fiber in a near- center location,
then uses a p ost- active staking to shift the fiber into the desired p osi-
tion within 0.2
µ
m. This process, plus the keyed axis, allows very pre-
cise core- to- core alignments. This connector is found on most Agilent
Technologies lightwave instruments.
