The HCP-M0200T is a 200 µm Hard-Clad Silica optical fibre designed for demanding industrial and scientific environments. Its pure silica Low OH core is optimised for efficient near-infrared transmission, especially around 850 nm, with low attenuation. The 0.37 numerical aperture and large core simplify light coupling from LEDs, VCSELs, and other broad-beam sources. A durable hard polymer cladding and ETFE buffer provide strong mechanical protection and reliable performance under vibration, bending, and chemical exposure. The fibre supports quick crimp-and-cleave termination, reducing installation effort and avoiding epoxy or polishing in many field applications. It is well suited to harsh industrial networks, optical sensing, medical laser delivery, and other applications where ruggedness and dependable optical performance are essential.
The HCP-M0200T is a rugged Hard-Clad Silica (HCS®) multimode step-index fibre built for applications that demand easy coupling, strong mechanical durability, and dependable near-infrared performance. Its 200 µm core, 0.37 NA, and Low OH silica construction make it especially suitable for use around 850 nm and in other NIR transmission tasks.
This fibre is a strong fit for industrial data links, optical sensors, medical laser systems, and high-power light delivery where installers need a more forgiving alternative to fragile all-glass fibre solutions.

FAQs
for HCS® 200 µm 0.37 NA Low OH Optical Fibre
A 200 µm core combined with 0.37 NA makes light coupling much easier from LEDs, VCSELs, and other broad-beam or misalignment-tolerant sources. The large core helps with optical power handling and relaxed positioning, while the high NA allows the fibre to accept light over a wider angle.
Low OH means the silica core contains reduced hydroxyl impurities. This lowers attenuation in the near-infrared range, especially around 850 nm and beyond, making the fibre better suited to NIR transmission, IR sensing, and laser delivery applications.
Yes. The fibre combines a hard polymer cladding, ETFE buffer, good bend tolerance, and resistance to many oils, solvents, and industrial chemicals. These characteristics make it a strong choice for factory automation, sensing, instrumentation, and other demanding installations.
This fibre supports crimp-and-cleave termination, allowing compatible connectors to be attached without epoxy or polishing in many cases. That can reduce installation time and simplify field connectorisation compared with more traditional all-glass fibre termination methods.
Typical connector options include ST and SMA styles, especially where ruggedness or high optical power delivery is required. Connector hardware should be selected specifically for 200 µm polymer-clad fibre to ensure correct fit and alignment.
Yes, the large core and silica light path make it suitable for many medical and industrial laser delivery applications. As with any higher-power optical system, connector choice, coupling quality, and thermal management should be considered to avoid localised heating at the termination.
