Thorlabs' Vytran® All-in-One Fiber Preparation and Fusion Splicing Workstation offers all fusion splicing and cleaving procedures integrated into a single system that can be used to produce consistent splices quickly and efficiently (US Patent: 9,977,189). This workstation uses our filament fusion technology to provide a convenient, reliable method of making high-strength, low-loss splices for both production and R&D applications. The splicer is capable of detecting and displaying the inner core structure of a fiber thanks to a high-magnification, high-resolution optical imaging system, enabling true core imaging. This technology provides for fast, accurate core alignment and splice loss calculation. Also included is a Windows® 10 PC with a user interface that offers complete configuration and process control. The model offered here is for SM and MM fibers.
The system is capable of processing fibers with Ø80 µm to Ø200 µm cladding. This includes standard Ø80 µm cladding / Ø180 µm coating and Ø125 µm cladding / Ø250 µm coating fibers.
Our FFS2000 All-in-One Workstation detects and displays a fiber's inner core structure; in conjunction with 0.01 µm resolution stepper-motor-controlled XY positioners, the FFS2000 provides a fast and accurate alignment system. Alternately, the stepper motors in the FFS2000 can also interface with external test and measurement equipment, such as power meters, spectrum analyzers, and polarimeters, through analog BNC inputs, to create a fully automated optical assembly station.
The workstation can also provide a splice loss determination after the splicing is complete. From the image of the fiber cores, a proprietary algorithm is used to accurately calculate the loss for a splice of a variety of similar or dissimilar fiber types.
Our unique filament fusion technology provides a consistent, reliable method of making high-strength, low-loss splices. Precise control of the fusion process is achieved by purging the splice region with an inert gas and using a tungsten or iridium filament to supply the thermal input necessary for fiber fusion. Because the fusion heat source is isolated from the environment, filament fusion splicing is not dependent on ambient conditions. Controlled conditions inside the system in combination with constant power control circuitry ensure repeatable performance splice after splice.
Our 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 will evaporate off of the hot center region of the splice and condense on either side of the joint where the fiber is cooler. The condensed silica deposits act as a surface flaw, lowering splice strength. The fire polishing process removes or minimizes the deposits, thereby improving splice strength. In addition, the fire polishing process provides capabilities to expand adiabatically the mode field diameter of a fiber by causing the dopants in the cladding to diffuse farther from the core. Through this thermal core expansion process, extremely low-loss fusion splices between markedly dissimilar fibers, such as those typically used in WDM applications, can be achieved.
The FFS2000 includes an optical fiber recoater to restore the protective polymer coating over the fusion splice. The combination of high-strength filament fusion splicing and UV acrylate recoating provides a more reliable alternative to standard heat shrink protection sleeves. The recoat process maintains a near-original fiber diameter and delivers a smooth, flexible fusion splice that can be handled or tightly coiled as if no splice were present.

|Filament Assembly Specifications|
|Fiber Cladding Diameter (Min / Max)|
|FTV7||Tungsten||80 µm / 200 µm|
|ETV7||Iridium||80 µm / 200 µm|
- Two Options Available:
- FTV7 Tungsten Filament Ideal for Most Applications
- ETV7 Iridium Filament Ideal for Soft Glass Fibers
- Omega Shape Provides Uniform Concentric Heat Source
There are two available fusion splicing filaments for the all-in-one workstation. The FTV7 tungsten filament is ideal for most splicing applications, while the ETV7 iridium filament is ideal for soft glass fibers. The omega-shaped filament is housed in an included mount and is easily replaced by the end user. The omega shape provides a uniform concentric heat source for fusing the fiber tips and for an optional post-fusion fire polishing step. Filament lifetimes will depend upon the particular splicing parameters used but are typically about 40 minutes.
One FTV7 filament comes pre-installed in the workstation. Additional filaments may be purchased, but before a new filament can be used in a system, it must be burned in. During the burn-in process, the filament is cycled between its operating temperature and room temperature several times. This stabilizes the thermal properties of the filament so that it produces a more consistent power output and heating performance when current is passed through it. This procedure only needs to be performed once, after which the filament will only need regular normalization. Instructional videos on the burn-in and normalization processes can be viewed in the Tutorial Videos tab above. If splicing performance begins to degrade, filament refurbishments can be ordered by contacting Tech Support.
|Compatible Coating Diameters|
|Item #||Recoated Diameter|
- Three Options Available for 280 µm, 430 µm, or 600 µm Recoat Diameter
- Other Sizes up to Ø900 µm Available Upon Request (Contact Tech Support)
- Maximum Recoat Length of 50 mm
- One Mold Assembly Required
There are three available recoater mold assemblies for the all-in-one fiber processing workstation. They are available for 280 µm, 430 µm, or 600 µm coating diameters. Custom mold sizes up to Ø900 µm are available; please contact Tech Support for more information. The assembly is composed of split quartz mold plates, which, when closed, form the cylindrical mold cavity around the exposed section of the fiber being recoated.
During operation, the recoat material (available in the next product grouping) is injected into the mold assembly with a manual injection system that is included in the workstation base unit. Then, UV light cures the recoat material. Cure times are dependent on the mold size and recoat material, but they range from approximately 12 - 15 seconds for the RM280 mold assembly with high-index AB950200 recoat material to 30 - 60 seconds with the low-index PC373 recoat material. The recoater mold assembly should be cleaned throughly with isopropyl alcohol or acetone between each recoating process; reliable and repeatable performance is highly dependent on the cleanliness of the mold.
One recoater mold assembly must be purchased in order to operate your workstation. The mold can be factory installed prior to shipment upon request by contacting Tech Support. If necessary, the recoat mold assemblies are user replaceable.
- AB950200: High-Index Recoat Material
- PC373: Low-Index Recoat Material
Thorlabs offers UV-curable acrylic recoat materials for the fiber processing workstation. We offer both high-index and low-index materials. The recoat material is injected into the recoater mold assembly by a manual injection system included in the workstation base unit. Each bottle includes 1 oz (30 g) of recoat material.
One bottle of recoat material must be purchased in order to operate your workstation.

The blade is shipped in a protective covering.
The ACL83 Diamond Cleave Blade is a replacement blade for the Vytran fiber processing systems listed to the right. Each system is shipped with a blade included.
When used with proper cleave parameters, a single location on the blade can provide up to 5,000 cleaves (dependent on the cladding properties of the fiber being cleaved). The blade can be positioned approximately 10 times before replacement (assuming proper cleave parameters and usage that does not cause unexpected damage to the blade). Blade replacement instructions for each system are provided in the user manuals.
Note: Severe damage to the blade can occur if conditions cause high stress perpendicular to the edge of the blade or if incorrect parameters are used to cleave the fiber.
