Take all the well-known features of our FSU 925 splicer, make them better, improve performance and package everything in a design that’s even more user-friendly and simpler to operate. The result? The new FSU 975.
You get enhanced versatility and functionality plus all the benefits of Ericsson unique loss estimation method. The splicer even comes complete with software for erbium, and for attenuating and tapering fibers.
That’s not all. The FSU 975 also has a fast splicing sequence and can store data for up to 150 splices.
The FSU 975, designed for all single-mode and multimode fibers, dispersion-shifted and erbium doped fibers.
The FSU 975 features Ericsson’s unique splice loss estimation method based on the mode coupling (microbending) theory and warm image processing and also takes splicing one step further by incorporating the unique Hot Core Alignment process.
In order to splice an erbium doped fiber to a standard single mode fiber or dispersion-shifted fiber with negligible losses, Ericsson has developed special software, the Mode Field Matching process, to be used within the FSU 975. This software eliminates the problems of splicing fibers with different mode field diameters.
With Ericsson’s unique Real Time Control (RTC) procedure, a full control of the fiber offset during fusion is obtained within the Attenuator making process. The splice attenuation can be controlled up to 29dB, with a typical accuracy better then 10% and a back reflection lower then – 70dB.
With the Pulling or Tapering process, own sequence for splicing fibers can be created. Tapering software is used mainly to produce fiber end faces that serve as microlenses. Fusion splicer 975 Kit
SPECIFICATION for FSU 975
Applicable optical fibers
Single-mode and multimode silica or low melting compound glass fibers irrespective of the refractive index profiles (matched cladding or depressed cladding for 1310nm, dispersion shifted for 1550nm or dispersion flattened for both 1310 and 1550nm) and irrespective of the coatings; tight secondary or loose tube, uncoloured or coloured fiber.
Fiber cladding diameter
Software is designed to perform splicing of the fibers with the cladding diameters between 30 and 270 µm with auto aligning and between 30 and 400 µm with manual aligning.
Fiber coating diameter
Up to 2 mm of coating diameters.
Loose tube secondary coating: Double mechanical nonbare fiber clamp (exchangeable) for primary coating and loose tube. Nom 0.250/2 mm. Tight secondary coating: Mechanical (exchangeable) for unprotected fiber and tight secondary coating. Nom 0.125/1 mm. For other dimensions, please consult Ericsson.
Automatic core or cladding for single-mode and multimode fiber in the Critical Splice Area (CSA), aided by the computer controlled image processor.
Messages displayed direct in the monitor
The FSU 975 gives the operator instructions and guidelines on how to operate the splicer throughout the whole splicing sequence. These instructions are displayed in English. Additional languages on request.
The FSU 975 automatically checks the quality of fiber ends regarding cleaving angle and remaining dirt, before splicing. The limit for the cleaving angle can be programmed in steps of 0.1°, from 0.1° to 5.0°.
Splice quality evaluating function
The automatic evaluation is made by an image computer scanning of the images obtained during the fusion process (warm-splice) in the Critical Splice Area (CSA). The attenuation of the splice is analysed by a patented
method, the microbending technique. This unique technique has considerably improved the accuracy of the loss estimation. FSU 975 also estimates a splice loss when splicing is done manually. The result is presented in the built-in 3” high-resolution LCD monitor as a value in dB.
The fusion time in Automode splicing including everything from preparation control to splice loss estimation is less than 45 seconds.
The range of the operation environment temperature is 0° to +45°C. The temperature inside is controlled by a built-in fan. Humidity must not exceed 95%. The range of the storage environment temperature is -20° to +60°C. Humidity must not exceed 95%.

Arc fusion splice method
Automatic prefusion and fusion by the built-in computer. Fifty different splicing programs (10 factory defined splicing programs are read-only) can be selected in Automode or Manual mode splicing, each either with 16 programmable parameters when splicing in normal splicing process or 19 programmable parameters when splicing in other splicing processes, which are easy to change.
Discharge between electrodes:
Arc: High frequency arc
Arc time: 0.1 to 30.00s in steps of 0.1s
Arc current: 6 to 30mA in steps of 0.1mA
Every user-defined program has its own key-number and access type: OPEN (every user can read and write), READ ONLY, CONFINDENTIAL (only the owner of the program can read and write).
The Arc-on Alignment (AOA) function makes a splice loss much more stable for the fibers with a smaller core size and the carbon coated fibers. With the AOA current, the fiber ends are align inside an arc with very low current, immediately before the fine alignment to avoid possible fiber bending (jumping) during alignment.
Automatic selection of currents
Automatic selection of prefusion and fusion currents shall use the Hot Core Alignment process. When the optimal parameters are met for fusion, the currents are memorised and stored in the splicer. This considers all external parameters that would affect the splice quality such as altitude, humidity, air-pressure, electrode ware, etc.
With the altitude compensation function, all parameters for fusion currents for the corresponding altitudes above sea level will be automatically calculated with approximation and the difference in altitudes above sea level will be compensated.
Typical splice loss
Typical splice loss is 0.02 dB for identical single-mode 9/125 µm fibers.
