Ensure engineers and produces premium connectivity components that help many of the world's best-known telecom and ISP operators meet the ever-growing demands on optical networks. Founded in 2002, we work alongside several industry-leading sister companies as part of the HH group.

A steep commitment to R&D and quality control gives Ensure its competitive edge. Highly specialized engineers and technicians work tirelessly to develop innovations that quickly become the benchmarks of the industry. 

What really sets Ensure apart is control of the manufacturing process from start to finish. With oversight of the entire production chain and an unwavering attention to detail, we have the ability to scale and adjust to meet the most demanding and specific customer requirements.

Ensure invests heavily in specialized equipment, taking great pride in the ability to manufacture our own PLC wafers and chips. Complex processes have been developed and perfected in our labs, such as plasma-enhanced chemical vapor deposition, inductively-coupled plasma, oxide deposition, UV photo, and ultrasonics.

Ensure's product catalogue includes ceramic ferrules that have high concentricity at both ends, guaranteed by laser-precise extrusion and machine processes. We craft our signature PLC splitters with various bandpass, splitting ratios, fiber types, and connector and packaging options. 

Innovation is also at the core of Ensure's passive network components, including customized solutions for advanced FTTx applications. We also offer a full package of WDM products for core, metropolitan area, and access networks. 

Ensure offers integration and assembly of customer components within our facilities, saving customers time and money. We can also produce white-label design and packaging, putting customer brands on our best-of-class products.
