Details
Note: as of March 9, 2026, we are offering the latest version of the Signal Fire AI-9 splicer.
This model has received a very big upgrade - it is equipped with a touch screen allowing most settings (including arc calibration) to be adjusted without the need for a phone and the SignalFire2 app. In addition, the kit comes with a Signal Fire S12 guillotine - a so-called 'one-step cleaver' that enables a full cutting operation to be performed in just one movement.
 |  |  |  |
The touchscreen allows to quickly switch on and off selected functions in the main splicing window and, after switching to the settings screen, to change most of the parameters necessary in daily work such as selecting the splicing program, changing the oven operating time, etc.
 | The included Signal Fire 12 guillotine allows the fibre cutting operation to be performed in just one movement. Made of magnesium and aluminium alloy, it weighs only 205 g. Equipped with an integrated waste container. It has easy access to the adjustment screws (from underneath) and the possibility to remove the lower cover to access the components that require periodic cleaning. The pre-installed blade has 24 cutting positions, enabling approximately 48,000 cuts to be made with an average cut angle of 0.6°. | |
Signal Fire is a rapidly growing company specialising in the manufacture of fibre optic splicers. Based in Chengdu, it employs nearly 200 people. The equipment they offer is built using components from renowned manufacturers. The company's products have found recognition in markets all over the world.
The Signal Fire AI-9 is a model in a line of fibre-optic splicers that has been used successfully for several years in fibre-optic installations of various categories. By refining the software and optimising the splicing process even better, the time of the entire process has been reduced to just 5 seconds. The low price is combined here with advanced technology for positioning and splicing optical fibres. The comfort of working on this device will be appreciated by beginners as well as advanced, experienced installers. The quality and reliability of the splicer has been confirmed in a number of tests performed in different environmental conditions and on different types of fibre.
Dipol is the official distributor of Signal Fire splicers in Poland. For Signal Fire AI-9 splicers from official distribution, Dipol provides 4-year warranty.Located in Krakow, the authorised service centre has qualified personnel and a stock of spare parts for all models. The failure rate of the brand's equipment, when used as intended, is minimal. |  |  | |
The kit includes:
- Signal Fire AI-9 fusion splicer
- toolbox
- set of spare electrodes
- fiber cleaver
- universal stripper
- stripper for flat cables
- bottle with dispenser
- cleaning brush
- carrying belts (for the splicer and the box)
- AC charger with USB adapter
Signal Fire AI-9 employs core alignment technology (there is option of cladding alignment) that ensures minimum attenuation of the splices. Fiber ends are positioned by 6 stepper motors from Siemens, which is an absolute exception in this price category. The splicer can be used both for deployment of hundred-kilometer-long fiber optic trunks and in FTTH systems requiring short point-to-point connections, in LAN installations and fiber-based video surveillance systems. The AI-9 model is controlled by a quad-core processor providing fast response times (the splicer is ready to work after 3 seconds) and ensuring short splicing and sleeve heating operations. The splicer is one of the fastest devices of its kind currently available on the market and the fastest in its price class.
5.1-inch screen with resolution of 800x480 pixels and adjustable brightness makes the operation simple and intuitive, even in difficult lighting conditions. The optical system offers magnification factor of 300, making it very easy to observe the splicing operations and visual analysis of the results (in two planes). The minimum splicing time is 5 seconds, and sleeve heating time (40 mm sleeves) is only 15 seconds. The included USB adapter allows to charge the smartphone or connect USB lamp powered from the USB port when working in the dark (no lamp included).
The universal fiber holders ensure comfort and speed of operations - they can hold 250 μm or 900 μm SM, MM fibers in tight buffer or loose tubes, pigtails, rubber-insulated fibers, multi fiber and DROP cables. The splicing machine offers various programs and Auto mode that works well in most situations.
The housing body is made of metal , underneath covered with rubber protection. The splicing chamber and heater cover are made of high quality plastics. The kit includes a practical box containing all the necessary tools, power supply and accessories (placed in two-level drawer mounted on durable metal guides). What is important, the installer does not have to take the splicer out of the box for splicing operations - the box provides a solid and stable support. The box is made of durable plastic and has a detachable element that can be used as a stool or small table.
The device is equipped with 7800 mAh rechargeable battery which has enough energy to perform 240 splices with sleeve heating cycles. The battery charging time is only 3.5 h. "Press & remove" design of the battery compartment allows for very fast battery change (there is a possibility to buy a spare battery). Additionally, the AI-8 splicer is equipped with a USB connector for charging a smartphone in the field from this high-capacity battery.
The splicer software allows the owner to enable a so-called "intelligent lock". In this mode, the owner has the possibility to limit the use of the splicer - for example when renting it. The following restrictions can be made:
- the splicer is locked by default; it is necessary to unlock using a pre-defined phone
- the splicer is unlocked to perform a certain number of splices - after that it will remain blocked
- the splicer is unlocked for a specified time (user defines a range of dates); after that, the splicer will remain blocked
Key features:
- embedded optical power meter and visual fault locator VFL
- possibility to set up a software lock of the splicer
- 6 motors for fibre positioning
- positioning to the core or to the fibre jacket
- auto mode capability
- image magnification x300
- 4-core processor for high speed operation
- minimum splicing time of 5 seconds
- quick oven - it takes 15 s to heat a 40 mm splice sheath
- configuration via phone app (Android/iOS)
- large (5.1'') display with adjustable brightness
- possibility to create welding reports with the dedicated application (export to xls),
- metal housing with rubber coating underneath
- high-capacity (7800 mAh, approx. 240 splicing cycles), replaceable battery
- battery charging time of approx. 3.5 h
- universal fibre holders
- high-quality, practical case
- rich set of accessories

The AI-9 model is equipped with an optical power meter and a visual fault locator modules.
 |  |  | Configuration can be done using the phone and the Signalfire2 app available on both Android (Google Play) and iOS (App Store). Through the use of the app, the installer has access and the ability to export the weld history to an *xls file. The splicer stores data of 1,000 spplices, data on subsequent splices can be stored in the cloud provided the user registers an account with the Signalfire2 application. Creating an account on the app allows the activation of further electrode sets (this should be done every 3,000 splices) and gives access to smart management functions for groups of splcers. These functions include, for example, the ability to rent a device for a certain number of days - after which time the splcer will need to be unlocked - or for a certain number of spicing cycles. Other features allow the user to be forced to scan a QR code (they must also have an account with the SignalFire2 app) visible on the start screen when switching on the splicer. This allows the administrator to keep track of when, where and by whom the device is being used. The application also gives the possibility to operate the splicing machine in fully manual mode - i.e. manual positioning of the fibres in two planes. | |
Notice: the warranty period for the rechargeable battery and cleaver is 12 months.
