Berkshire Photonics offers a full line of step and graded index multimode fibers, used in medical equipment, fiber sensors, communication devices, optical devices, and laser applications. For more than 10 years, we’ve focused on specialty and custom multimode optical fibers, delivering quality products to our customers. These fibers are available in a variety of sizes, numerical apertures, water contents, and buffer materials. We also offer customized fiber optic connectors, assemblies, and accessories to match your required multimode fiber.
Berkshire Photonics offers a selection of graded index multimode fiber, optimized at both 850nm and 1300nm. Fibers range from standard 50/125µm up to 300µm core size, with numerical apertures ranging from 0.14 to 0.29. Custom fibers are available with different core and clad sizes, as well as custom numerical apertures. These doped core fibers are perfect for sensor and laser transmission, data communications, optical devices, and medical applications. Benefits include high coupling efficiency, power transmission, and performance bandwidth with low attenuation.
Our company stocks standard and specialty step index silica/silica fiber, including our low OH 0.15 and 0.22NA fibers. However, additional fibers are stocked and available for purchase. We also offer custom core and clad sizes, buffer materials, numerical apertures, and UV fibers. Listed are Berkshire Photonics’ acrylate coated and ETFE buffered fibers, which are ideal for high power applications. All fibers are available as a stand alone product or in a jumper or bundle assembly customized to your specific needs.
We carry a full line of step index multimode, hard polymer clad fibers. These fibers are versatile and are often used for sensors, spectroscopy, laser delivery, factory automation, and data communication applications. H-PCF fiber has many advantages, including easy epoxy polish or crimp and cleave connector terminations, high coupling efficiency due to the large core and high NA, and is a cost-effective alternative to standard glass/glass fibers. Berkshire Photonics stocks 0.37NA HPCF fibers, ranging in size from 200µm to 600µm, and can provide additional sizes and NAs upon request.
