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 

Determination 

CAS splicers utilize True Core Imaging TM , 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 Polishing 

Vytran’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.

LARGE DIAMETER CLEAVER 

Precision Cleaver for Standard, Large 

Diameter and Specialty Optical Fibers 


LDC-400 

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 tensionand-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 mirrorquality 

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. 

Key Markets 

Telecommunications • Aerospace and Defense • Fiber Laser • Sensing • Medical • Research 

Options 

Angle Cleave 

The angle cleave option adds a rotary drive 

mechanism that can introduce a torsional 

component to the pre-scribe tension. This can 

be used to produce angle cleaves of up to 15 

degrees, a common requirement for reducing 

back reflections at a cleaved end-face. 

Fiber Holding Block Inserts 

A series of individual fiber holding block inserts, 

or a full set, can be purchased for fiber sizes 

from 80 microns to 1.25 mm. 

PCF and Large Diameter cleave 

backstop 

This option is required to cleave photonic 

crystal fibers and very large diameter fibers. 

It enables a smoother cleave surface.

Filament Fusion Provides Repeatable, 

High-Quality Splices 

Vytran’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-4000 

Filament Fusion Technology for Precise and Consistent Splicing 

Fire Polishing Enhances Splice 

Strength 

Vytran’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-4000 

Complementary Product Suite for Development 

through Volume Production 

Splice Loss Estimation 

The 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 Imaging 

The 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 microstructured 

cores. 

Dual Screen Software Interface 

The PC-based laptop software features two 

complementary screens. The “development” 

screen allows users to access all of the unit’s 

functionalities for full process optimization. 

The password-protected “production” screen 

allows only basic system operator interface for 

efficient volume manufacturing.

PTR-200 SERIES 

FIBER RECOATERS AND PROOF TESTERS 

A Complete Series of Products for Coating 

Restoration and Reliability Testing 



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 

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. 

Split quartz mold with fiber 

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. 

Split quartz mold 

Proof Testing 

Key Markets 

Recoated fiber 

Vytran 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.

Manual Recoat 

The 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, lowvolume 

requirements, or if the mold size or 

process must be changed frequently. 


Automatic Recoat 

The 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 highvolume 

fiber processing.

Proof Testers 

The 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 highvolume 

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.

The standard control interface for all models is via RS-232, allowing easy integration into existing 

manufacturing software. Vytran also offers additional control/display interface options, including a minicontroller 

display, which provides system status only. The mini-display is a common option for repetitive 

production applications where the operator does not need to change process parameters.

POLYIMIDE RECOATER 

High Temperature Recoat Protection 

and Linear Proof Testing 


PTR-200-PRL 

The 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, hightemperature 

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 Process 

The 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.
