Nextrom puts the special into specialty fiber production

Nextrom provides solutions for all your needs regarding specialty preform and specialty optical fiber fabrication.

To serve this diverse market, Nextrom offers a comprehensive range of customizable and cutting-edge manufacturing solutions for a wide range of specialty preforms and optical fibers.

Specialty optical fibers are optimized for applications other than signal transmission, such as lasers, sensors, filters, ring resonators, etc. For such varied applications, there are hundreds of different specialty optical fiber types with many variations in glass composition, core and cladding structures, geometric properties, coatings, and specially tailored optical performance characteristics.

Solutions from start to finish

Nextrom offers glass-working, sleeving, and collapsing lathes specifically designed to complement PCVD and MCVD processes in specialty preform production.

Specialty preforms are then drawn into Nextrom’s state-of-the-art fiber draw tower, which is designed to produce any kind of specialty fiber type imaginable to fulfill your needs.

These fibers can then be proof-tested by a specially designed proof-tester for specialty fibers to test the fiber properties and ensure the high-quality end-product associated with our production lines and brand.

Production solutions cover all the steps required to produce your own specialty preforms using either MCVD (modified chemical vapor deposition technology) or PCVD (plasma chemical vapor deposition technology).

Nextrom’s MCVD OFC 12 – Modified Chemical Vapor Deposition System is a well-known and widely used method for the fabrication of high-quality preforms to produce first-class end-products for specialty and laser optical fiber production.

With hundreds units delivered since 1990, Nextrom’s MCVD is the most widely used MCVD system in the industry.

As with all Nextrom preform-making equipment, all gas lines and connections are made of ultra-high purity stainless steel. 

Nextrom´s solution for producing preforms using the MCVD process for specialty fiber draw is widely used by well-known universities and commercial manufacturers across the globe.

Nextrom’s PCVD OFC 12P – Plasma Chemical Vapor Deposition System provides unrivaled control of the refractive index profile.

Manufacture first-class preforms with high accuracy index profiles and with high numerical aperture and doping levels for specialty and laser optical fiber production.

Nextrom offers unrivaled purity during the PCVD deposition process by providing a leak-free process for specialty preform production with an optimal final result.

Custom-designed rotary seals and reliable and repeatable processes ensure first-rate preforms for its users. 

As with all Nextrom preform-making equipment, all gas lines and connections are made of ultra-high purity stainless steel. 

Nextrom´s solution for producing preforms using the PCVD process for specialty fiber preform production is widely used by well-known universities and commercial manufactures across the globe.

The horizontal glass-working and sleeving lathe system – OFC 15 is used for glass and preform processing in specialty fiber production. The lathe is suitable for various glass-working operations as well as for fire polishing and tube sleeving.

Also, the lathe can be used for collapsing process. Once deposition phase is complete, the preform must be collapsed into a solid rod/preform before it can be drawn into specialty fiber.

Lathes are supplied with all the instrumentation needed according to customer specific needs for high quality glass-working, sleeving or for collapsing purposes and is equipped with special burners for optimal results.

Nextrom’s solution for glass working and sleeving for Specialty Fiber production are widely used within well-known universities and commercial manufacturers across the globe.

The Nextrom OFC 20 SF fiber draw tower for specialty fiber production is available with different furnaces and precise preform feeding solutions for soft glass, silica, and plastic optical fibers. Flexible production of a wide selection of specialty fiber types to cater to specific needs.

High-quality components and solutions in the Nextrom specialty fiber draw tower guarantee excellent production conditions and quality operation in the short term and provide strong reliability in the long term.

Continuous improvement, development, and research programs regarding the specialty draw tower ensure that it’s always at the forefront of technology for new and existing users of Nextrom’s specialty fiber draw solution.

Nextrom’s solution to draw specialty fibers is widely used by well-known universities and commercial manufacturers across the globe.

 

 

The Nextrom OFC 35 SF is an axial tension proof-testing system specially designed for specialty fibers, with extended tension ranges for tensile testing and large diameter proof-testing using integrated bending wheels to test fiber strength in 8 directions. It is a highly accurate system where the resolution is maintained with multiple tension gauges for different fiber ranges.

In order to meet the requirements of specialty fibers, special attention has been paid to high-quality take-ups and pay-offs, flexible configurations, quick setups, ease of operation, and maintenance. A top performance level is reached by means of efficient servo motors, high-accuracy tension sensors, and special design dancer which guarantee effective winding at high speeds. A cutting plan can be keyed into the unit so that it stops when the desired length is reached.

When designing the OFC35 SF, special focus was placed on the ergonomics and ease of use, as well as on safety. The operator only needs to change full reels in the pay-off and empty reels in the take-up. It is a system that is easy to handle, and it fulfills international proof-testing standards.

Nextrom’s solution to proof-testing specialty fibers is widely used by well-known universities and commercial manufacturers across the globe.
