Jan 2026
From preform creation to final fiber, Nextrom
covers every step of specialty fiber
manufacturing. OFC 12 MCVD (Modified
chemical vapor deposition) and OFC 11
PCVD (plasma chemical vapor deposition)
systems produce high-purity preforms with
precise doping profiles. Glass-working and
collapsing lathes for preform refinement.
Finally, the OFC 20 SF draw tower and
proof-tester ensure top-quality specialty
fibers — multimode, hollow core, and more.
