fusion splicer program is based on good local service support and careful model selection

When choosing the most optimal fusion splitter model, it is first necessary to define for what purpose the device will be used. Rough flooring can be made by defining three basic applications:

  1. FTTx Splicers - Creating and maintaining access networks - FTTx or local area networks (LANs, data centers, video surveillance, ...)
  2. Backbone splitters - Design and maintenance of trunk telecommunication routes
  3. Universal - Creating access and backbone networks.

The choice of model is also significantly influenced by the number of devices needed - be it one unit, or for example 5 or more units .... If more units are needed, it is easier to make the optimal combination even with a more modest budget.

Lastly, and perhaps most of all, local service support is essential when choosing a splitter model.

Selection of fusion splicer models distributed by SIFON d.o.o.

With the distribution and servicing of fusion splicers, Sinfon started in 2016, from the beginning with a strong focus on customer support. The choice of the model was limited to only two universal purpose devices - affordable enough to be used for FTTx or GPON networks (L4 projects), but also precise enough to build trunk lines. These are the famous and popular DVP-740 clad to clad models and the Tumtec FST-83A core to core alignment model. Both models are 4-cylinder units.

Since 2019, two models are being introduced to the program for the most demanding applications, backbone construction. These are models that use 6 motors for precise positioning of optical fibers. Also, a new model for FTTx (FST-18S) is introduced that has outstanding features.

Splicer models that have only 2 motors and are only usable on local (LAN) and access (FTTx) networks are not currently in our product range, but we have experience in servicing them. The introduction of these devices for sale is possible in 2020.
