Compact, Semi-Automated Splicers
High PerformanceAt the foundation of CAS-4000 systems is our proven filament fusion technology—the industry’s most reliable method for creating high-strength, low-loss splices.
Compact and Efficient DesignIn both CAS-4100 and CAS-4100-P, all components, including the imaging system, computer and folding display, are embedded into the splicer to form a single unit ideal for use where space is at a premium.
Ideal for Standard and Specialty FibersCAS-4000 systems can be used to splice specialty fibers (doped, PM, ZBLAN, Chalcogenide, PCF) and fibers with diameters as small as 80 µm. They can also be used for many other applications, such asmanufacturing end caps, thermal core expansion, splicing fiber lenses and more.

One Step Splice™CAS splicers feature our unique One Step Splice process software—a system designed to make splicing simple and user friendly. The GUI provides two modes of operation:
• In “Operator” mode an ultra-simple screen features a single splice button that initiates the splice process.
• In “Development” mode an intuitive and streamlined screen allows full process configuration and control.
All splice-related information can be exported via an Ethernet port for statistical process control.
End-View Imaging and Splice Loss DeterminationCAS splicers utilize True Core ImagingTM, a high-resolution imaging system that enables fast, accurate, inner-core alignment and splice loss calculation. Vytran has developed a proprietary algorithm that accurately calculates loss for splicing a variety of similar or dissimilar fiber types. CAS splicers also feature an End-View Imaging system for looking directly at the ends of the fibers prior to splicing. This is used in conjunction with high-resolution rotary positioners for the automated alignment of PM fibers through either image-based or active feedback control. End-View Imaging is also ideal for working with fiber laser gain fibers, which may have non-circular claddings or micro-structured cores.
Patented Fire PolishingVytran’s fire polishing process increases splice strength through a rapid post-fusion heat treatment of the splice region. The process: • removes or minimizes deposits, improving splice strength. • provides core diffusion capabilities that can be used to adiabatically expand the mode field diameter of a fiber. • enables low-loss splices between markedly dissimilar fibers.

LDC-400LARGE DIAMETER CLEAVER
Precision Cleaver for Standard, Large Diameter and Specialty Optical Fibers
Strip Clean Cleave Splice Recoat Test
The LDC-400 is a versatile optical fiber cleaver that can be used to produce precise and consistent flat and angled cleaves on fibers ranging from 80 microns to 1.25 mm (coating up to 3 mm) in diameter. This tension-and-scribe system combines the well-proven precision diamond blade scribing technology used in Vytran’s LDC-200 and LDC-200-G cleavers and FFS-2000 fusion splicing workstation with the tensioning capabilities of our linear proof tester products.
By using the same tension-and-scribe method that works so well to cleave telecom fibers, the LDC-400 handles large specialty fibers, yielding flat, perpendicular cleaves with mirror-quality end-face finishes.
The cleaver is fully automated with programmable cleave tension, rotation angle and scribe conditions, and includes special processes for cleaving photonic crystal fiber (PCF), highly stressed fibers, or capillary tubing. The LDC-400 can also be used to cleave many non-circular fibers typically used in fiber laser systems. It uses the same bottom v-groove inserts as our GPX and LFS systems, and through the use of a transfer clamp the cleaved fiber can be conveniently moved from the cleaver to the GPX/LFS system. The fact that the registration is maintained and programmable between the cleaver and splicer allows for easy fabrication of end-caps and mode field adaptors. Fiber inserts must be ordered separately based on the range of fiber sizes to be used.

Filament Fusion Provides Repeatable, High-Quality SplicesVytran’s filament fusion technology is a consistent and reliable method of making high-strength, low-loss splices. Under purge of an inert gas, a resistive heating element supplies the exact amount of thermal energy necessary for fiber fusion. The heating element’s size, shape and power delivery can be changed to suit the application, easily scaling to very large diameter fibers.
The filament furnace assembly can also be moved along the length of the fiber, making many specialty processing applications possible, such as post-splice fire polishing for strength enhancement. These highly controlled conditions, in combination with constant power control circuitry, ensure repeatable performance splice after splice.
LFS-4000Filament Fusion Technology for Precise and Consistent Splicing
Fire Polishing Enhances Splice StrengthVytran’s patented fire polishing process significantly increases splice strength through a rapid post-fusion heat treatment of the splice region. When a fusion splice is made, silica evaporates off of the hot center region of the splice and condenses on either side of the joint where the fiber is cooler. The condensed silica deposits act as a surface
flaw, lowering splice strength. Our fire polishing process removes or minimizes the deposits, thereby improving splice strength.
In addition, the fire polishing process provides core diffusion capabilities that can be used to adiabatically expand the mode field diameter of a fiber. Through
this thermally expanded core (TEC) process, low-loss fusion splices can be achieved between markedly dissimilar fibers, such as those typically used in fiber laser applications.

LFS-4000Complementary Product Suite for Development
through Volume ProductionSplice Loss EstimationThe LFS-4000 uses Vytran’s True Core Imaging™ technology for precise fiber core alignment prior to splicing. Because this technology provides a clear view of the fiber’s inner core, an accurate estimation of splice loss can be achieved based on an analysis of the completed splice. Vytran has developed a proprietary algorithm that accurately calculates loss for splicing a variety of similar or dissimilar single mode fiber types with a high correlation factor. End-View ImagingThe LFS-4000 features a unique End-View Imaging system for looking directly at the ends of the fibers prior to splicing. This is
used in conjunction with high-resolution rotary positioners for automated alignment of polarization maintaining (PM) fibers through either image-based or active feedback control. End-View Imaging is also a powerful tool when working with fiber laser gain fibers, which may have non-circular claddings or micro-structured cores.

PTR-200 SERIESFIBER RECOATERS AND PROOF TESTERS
A Complete Series of Products for Coating Restoration and Reliability Testing
Strip Clean Cleave Splice Recoat Test
PTR-200 Series
Vytran optical fiber recoaters restore the protective UV acrylate buffer coating to a stripped or fusion-spliced section of optical fiber. Because the recoat diameter and recoat material can be closely matched to the original fiber, the recoated section of fiber is smooth and flexible, and can be handled or coiled just like the original fiber. When used in conjunction with a proof test qualification, recoating offers significant packaging and reliability advantages over standard heat shrink protection sleeves.
All Vytran recoaters use split quartz mold plates, which, when closed together, form a circular mold cavity around the exposed section of fiber. A volumetric dispensing pump automatically injects a pre-programmed amount of recoat material into the mold cavity, which is then cured by exposure to ultraviolet (UV) light. Special optical coatings on the surfaces of the mold plates prevent any recoat material that migrates between the plates from curing and forming a “flash” on the finished recoat.
Vytran is the world’s leading provider of optical fiber recoaters and proof testers. Various product configurations allow the customer to select among three types of recoat stations - manual, extended length manual, or automatic - and two types of proof test stations - rotary or linear. These stations can be ordered individually or in selected recoat/proof test combinations as listed in the Model Configuration Table.

Protective Coating Restoration and Proof Testing/Tension Testing
Proof TestingVytran optical fiber proof testers apply a set load at a controlled rate to an optical fiber or fusion splice. The load can be taken up to a pre-determined level and released - proof test mode - or it can be taken up to the breaking strength of the fiber - tension test mode. The peak tension is recorded and can be displayed in units of tension (pounds, kilograms or Newtons) or stress (kpsi or GPa). By selecting a proof test level approximately three times higher than the applied service load on the fiber or fusion splice, the long-term reliability of the fiber can be assured.
PTR-200 SeriesManual RecoatThe manual recoat mold has a hinged top that is opened and closed by hand. Recoat material is injected into the mold cavity via a cross channel in the mold top plate. The manual mold is well suited for R&D applications, low-volume requirements, or if the mold size or process must be changed frequently.
Automatic RecoatThe automatic recoat mold uses a pneumatic gripper assembly to automatically open and close the mold plates in a front-to-back direction.This allows direct injection of the recoat material into the mold cavity without any excess material to clean after every recoat. Once the fiber is positioned in the fiber holding blocks, the entire recoat process is performed automatically. Continuous, fully automatic operation makes this an ideal system for high-volume fiber processing.
Proof TestersThe linear optical fiber proof tester is intended for production proof testing of up to 20 Newtons (235 kpsi for a 125 micron fiber). The linear proof tester can be combined with either the manual or automatic recoater. This makes the linear proof tester well suited for high-volume production processing.
The rotary optical fiber proof tester/tension tester features Vytran’s rotating mandrel design. To proof or tension test a fiber, the section of fiber to be tested is located between two mandrels. A load is automatically applied to the fiber by the rotation of the right-side mandrel. The rotary proof tester is ideal for process qualification where high proof test/tension test levels are required.

High Temperature Recoat Protectionand Linear Proof Testing
Strip Clean Cleave Splice Recoat Test
PTR-200-PRLThe PTR-200-PRL is a stand-alone optical fiber recoating system designed for the application of polyimide coatings. A “drawing” process applies the polyimide resin which is then thermally cured to form a hard, high-temperature recoat. A single layer application takes around 60 seconds and results in an approximate thickness of 3-10 µm per pass, depending on the coating material. Multiple layers can be applied for higher reliability and increased coating diameters. The resulting recoat has mechanical and thermal properties similar to the original polyimide-coated fiber.
Fully Automated ProcessThe section of fiber to be recoated is located between two fiber holding blocks. Once the recoat process is initiated, the polyimide resin is automatically pumped to a drawing head via a volumetric pump. The drawing head, which consists of dual dies and dual heaters, automatically makes the user-specified number of “passes” along the section of fiber. Each “pass” applies a coating of resin, followed by a low-temperature bake to remove volatiles and then a high-temperature bake to imidize and harden the coating. The integral linear proof tester ensures that proper tension is applied to the fiber during the recoating process and allows for proof testing of the recoated section of fiber.
