    General The microprocessor-controlled fusion splicer is employed to produce mechanically strong, durable and low-loss connections between optical fibers. Fiber diameter It is possible to connect single-mode fibers, dispersion-shifted single-mode fibers and multimode fibers up to a maximum coating diameter of 900 µm. The splicer is designed for the standard fiber outside diameter 125 µm (without coating).

    Attenuation Splice with Standard Single-Mode Fibers If you want to make attenuation splices with standard single-mode fibers, you merely need to read the section "Making an Attenuation Splice" from the next page onwards. There, you will also find references to further information if you do not obtain the re- quired results.

  • Page 74: Operation Of The Attenuation Splice Program

    Operation of the Attenuation Splice Program The fibers are positioned in the same way as with all LID programs. Immediately before it commences fusion, the fusion splicer automatically sets a radial offset of the fiber axes. The fusion process consists of an initial fusion phase followed by one or more fusion pulses and runs fully automatically until the required attenuation is reached (see drawing).

  • Page 75: Fusion Sequence

    Fusion The first fusion phase takes the same form as in the other programs. Up to 20 fusion sequence pulses are then generated at intervals of approx. 1 s until the required attenuation is reached. Level display After the first fusion phase and after each fusion pulse, the current LID level and the target value are displayed as relative level values.

  • Page 88 General rules The following rules apply to practically all single-mode fibers. Deviations from these rules are required only for very few special fibers in the event, for instance, of blistering. If seeding occurs in splices, follow the notes on fusing multimode fibers further on in this section.
  • Page 89 "Fixed parameters Optimize if possible the parameters using the LID system as described above. You can (video)" then use the optimized parameters in the video program. If the LID cannot be used, employ the method described below. This method requires an external attenuation test set because in the video programs the attenuation display provides correct results only if the parameters have already been correctly set.

  • Page 90: Service Support

    Service support The splicer provides what is referred to as "Service support". With the service support it is possible to detect various problems including loss of alignment and contamination of the optical components. To use the service support, this function must be activated. It then remains active until either the splicer is switched off or, as described below, the "splicer software"...
  • Page 91 Activating the LID profile display Select "LID profile display" with button Activate "LID profile display" with button Examples for assessing the splice parameters Note For optimization trials on application-specific parameter sets use only the parameter sets 2 to 5. Do not change the first parameter set if you can avoid it! If you cannot ob- tain optimum parameters, you can then at least continue with the first parameter set (default / standard set).
  • Page 92 This level curve is typically the result of non-optimally set splice parameters. The level falls sharply just before the start of the main fusion. The reason for this is inadequate heating of the fiber during prefusion, i.e. the prefusion time is too short, the prefusion current too low or the fiber feed is too great.
  • Page 93 Menu "Test In the menu "Test functions" the following submenus can be selected: functions" • Dirt check • Illumination check • Column/line digitization • Piezo test The submenu "Column/line digitization" should only be used by the service center. This section is not relevant for the craftsperson in the field. The other two sections can be used to perform selective troubleshooting on the splicer.

    Fault messages The following pages contain explanations to the fault messages displayed on the on the monitor monitor, together with notes on remedying the faults. The fault messages are arranged according to the operations in which they occur. Note that a number of fault messages can have different causes and symptoms and may therefore be listed more than once on the following pages.
