Figure 6-3. 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
6-4.

The nickel silver allows an active centering process that permits the glass fiber to be moved to
the desired position. This process first stakes the soft nickel silver to fix the fiber in a near-center
location, then uses a post-active staking to shift the fiber into the desired position within 0.2 mm.
This process, plus the keyed axis, allows very precise core-to-core alignments. This connector is
found on most Agilent Technologies lightwave instruments.
