Selecting guide of fusion splicer

TYPE-72C T-55 T-400S TYPE-201e-VS TYPE-71M12 TYPE-201e-M4

The number one thing to know about fusion splicers: how to choose one depending on the job at hand.
A number of perspectives on how to choose a fusion splicer are given below. Please refer to this when choosing one of our fusion splicers for purchase.

  1. (1) Choosing by cable type

     The cables laid down in network construction are one of two types, single fibre and ribbon fibre, and these correspond to two types of product: single fibre fusion splicers and ribbon fibre fusion splicers respectively.
    Ribbon fibre fusion splicers are used with ribbon fibre, enabling them to splice multiple fibres at once, and giving them the advantages of efficient use of the wiring space and a shorter time needed to carry out the work. On the other hand, due to the mechanism design, single fibre fusion splicers allow high-precision alignment, providing the advantage of low-loss splicing.
     Our company offers a wide line up of fusion splicers, starting with the TYPE-71M12 for ribbon fibre fusion splicers and the TYPE-72C for single fibre fusion splicers. Below, I will explain some ways to think about choosing a machine, focusing on single fibre fusion splicers.

  2. (2) Choosing by fibre type

     For modern fibre-optic networks, depending on their purpose, each fibre manufacturer independently designs, manufactures and sells worldwide not just standard SMF/MM fibre, but also various other types, including BIF (Bend-Insensitive Optical fibre, which is less sensitive to stress, particularly bending) and NZDSF (Non-zero dispersion-shifted fibre, which is designed to overcome the problems of dispersion-shifted fibre). In order to splice these optical fibres with high precision and low loss, more powerful fibre identification features are necessary. Our single fibre fusion splicers form a product lineup perfectly suited for these jobs, from the entry model T-55 to the TYPE-72C, which is capable of high-performance optical fibre identification.

  3. (3) Choosing by network type

     For fibre splicing in backbone networks, connect points that may be separated by many kilometers, occasionally dozens or hundreds of splicing points are necessary. In order to make these splices with the absolute minimum of loss, a high-end machine such as the TYPE-72C is most effective. Our fusion splicer lineup also features the specialized FTTH splicer T-400S. And for cases such as the last one mile connection of an FTTH network, where some level of loss is acceptable, the T-55 is popular for use in access networks. We offer many other products to suit the capabilities and costs required by each kind of network construction.

  4. (4) Choosing by construction environment

     Together with the increase in transmission capacity of metro networks or connections between data centres, optical fibre cable is becoming multi-core, and the number of cores that need to be spliced for each job has risen from the hundreds to the thousands. In order to carry out these jobs efficiently and quickly, the most important point is to be able to perform fusion splicing and sleeve protection in a short amount of time.
     The TYPE-72C can perform splicing in 6 seconds, a world record, and sleeve protection in 14 seconds, giving it the perfect level of performance for this kind of use. Conversely, for FTTH use, there may be only a few splices per job, but they may be located in difficult environments for splicing work, such as on poles, under eaves, or in narrow MDF rooms.
     In these sorts of environments, specialized FTTH splicers like the lightweight and easily operable TYPE-201e or T-400S are most suitable.
     Other things to consider when choosing a product by work environment are features that provide durability in outdoor construction work, such as dust-proofing, rain-proofing, resistance to impact and vibration and sustained performance at high altitude.
