Fiber Ferrules, Adapters, Connector Housings…
The core metal components of optical communication devices require Ø0.7–5mm ultra-high concentricity and ±0.002mm precision tolerance — one of Jian Chang's core production specialties.
To meet the optical communications industry's demanding requirements for concentricity, surface finish, and dimensional consistency, Jian Chang delivers with proven Swiss-type turning production.
The exact machining challenges of optical communication metal parts are where Jian Chang's Swiss-type turning excels.
Below are metal parts commonly requiring precision turning in the optical communications industry. Jian Chang can machine to customer-supplied material or drawing.
