Chapter 2 Safety
WARNING
The filament in the glass processor furnace generates intense light when it is in operation. It is
strongly advised that the user does NOT look directly at it during splicing or tapering operations.
CAUTION: HOT SURFACE
The furnace gets extremely hot when the filament is turned on. Do not touch the furnace during or
immediately after the filament has been on for a few seconds, such as after a splice or tapering
operation.
WARNING
The fiber handlers and the splice head can exert a fair amount of force as they move from side to side.
Do not put your fingers between them, or between the fiber handlers and the slot end walls, while the
machine is in operation.
DANGER
The camera tower on the glass processors can generate a fair amount of force as it moves forward
and backward, and up and down. Do not put fingers between it and the furnace or mirror tower while
the machine is in operation.
CAUTION
Be sure your electrical power and gas supplies meet the criteria detailed in the Chapter 8.

Chapter 3 Description
3.1. Introduction
Thank you for purchasing a Vytran®Glass Processor. This manual is intended to convey the basic instructions
necessary for operating the glass processor.
The Vytran Glass Processors are a versatile glass processing platform for the fabrication of splices, tapers,
terminations, couplers and combiners. All systems incorporate a filament furnace assembly that provides a stable
high temperature heat source for precise control of glass processing conditions. An embedded real time control
system and powerful machine level macro programming language allow the user to develop unique event-driven
routines for fast and flexible process development. All high level system communication is through a user-friendly,
PC based graphical interface that provides for easy operation and convenient data storage. This level of control
combined with the consistency of filament fusion technology makes the glass processors a multipurpose platform
for the production of fiber laser and other specialty fiber applications.
The Vytran Glass Processors consist of four different models designed to perform high-quality fusion splicing and
tapering of specialty fibers. The system consists of a filament-based heater, precision stages with multi-axis
control, microscopic high resolution CCD imaging system and a personal computer. The filament assembly can
heat optical fiber to temperatures up to 3000 °C, which makes it possible to fuse and process various fiber types
and sizes. The multi-axis stages precisely control and aid the alignment and positioning of the fibers for high
quality splicing and tapering. The imaging system displays magnified fiber image with sub-micron resolution. The
fiber can be viewed both from fiber side and fiber end. All glass processors have the ability to rotate fibers;
making it possible to align PM fibers, eccentric core fibers or non-circular fibers.

3.4. System Overview
The Vytran Glass Processor has three basic components: a splicing and glass processing workstation, a personal
computer (PC), and a gas supply. The splicer workstation is illustrated in Figure 1.

Page 8 TTN047532-D02
3.4.1. External Workstation Connections
The splicer workstation is the main component of the glass processor. The PC and gas supply, as well as
peripheral components, are connected to its back panel as illustrated in Figure 2.
Figure 2 GPX3400 Back Panel Connections
Power
The glass processor workstations are powered from an external dual voltage supply. The GPX3400 uses
a 5-pin round connector. The GPX3600 utilizes a 2-pin 24 V and 3-pin 12 V power cord.
Communication
PC – GPX Control communication:
RS-232, 9-pin D-Sub connector. Connect to Com 1 on the PC
Camera – PC: IEEE-1394 6 pole connection. Connect to IEEE-1394 on PC
Analog Output: 2 BNC connectors - Analog 1 & Analog 2
Gas
Argon: 1/8" Push fit connector

3.4.2. Fiber Holding Blocks
The fiber handlers are used for holding, positioning and moving the fibers during the various processes
implemented on the a glass processor workstation. The GPX3400 and GPX3600 fiber handlers that can align
fibers prior to splicing. Fiber XY alignment can be performed using either the edges of the fibers, or their cores.
The GPX3400 and GPX360 fiber handlers can also perform a rotary alignment. Rotary alignment is useful for
aligning the stress members of PM fibers, for aligning the cores of eccentric core fiber, and for aligning surface
features of non-circular fiber.
GPX3400 and GPX3600 Fiber Holding Blocks
The GPX3400 and GPX3600 fiber holding blocks can rotate each fiber up to 200°. This is primarily used for
aligning stress members of PM fibers, but can also be used to align the cores of eccentric core fibers. It can also
be used to align surface features on fibers that are not round.
Rotary Fiber Holding Block
Fiber Holder Inserts
Different sized bottom V-grooves and top inserts are available for various coating fiber diameters. For available
insert sizes, please see the selection chart in Chapter 7. In addition to the standard sizes, custom inserts may be
specially designed for various applications. Contact Thorlabs for more information.
