ULTIMODE BS-24SM belongs to an innovative system of fiber optic cabling with easy fiber access, especially useful in high-rise and multi-dwelling buildings. The fibers can be branched directly to individual subscribers without the need for splicing within the riser of the building. They are easily extracted from breaking windows in the gel-free tube.

The construction of ULTIMODE BS cables allows the installer to cut out windows in the sheath (tube) and pull out single fibers without a risk of damage, thanks to a proper inner diameter of the tube. Additional protection is provided by two aramid rods in the sheath, which, in addition to strengthening and stabilizing the tube, act as protective barriers to the stripper blade.

ULTIMODE BS-24SM cable contains 24 single-mode fibers. The color identification of the buffer layers complies with the GB13993.3-2001 standard. The jacket (sheath) is made of low smoke zero halogen flame retardant poly-olefin (LSZH).

Single-mode vlákna použité v tomto kábli sú ITU-T G.657.A2, v 900 um tesnom opláštení. Vlákno G.657.A2 je v súčasnej dobe jedným z najmodernejších a najpopulárnejších single-mode vlákien, čo je v skutočnosti vylepšená verzia G.652.D vlákna. Vlákno môže byť formované do tesnej cievky v dôsledku zníženia útlmu v takýchto podmienkach, zatiaľ čo ostatné parametre sú ešte o niečo lepšie (útlm menší ako 0,35 dB / km pri 1310 nm a menej ako 0,20 dB / km pri 1550 nm). Zvláštnosťou tohto typu vlákna je znížený útlm cievok - pri 1550 nm je útlm 10 otáčok s polomerom 15 mm, je <0,03 dB, a na 1 otáčku s polomerom 7,5 mm, je <0,5 dB.

Of course, the minimum bending radius of the fiber and of the cable is not the same. The former depends on the standard and physical characteristics of the fiber, whereas the latter should be assumed as 20x the external diameter of the cable.

ULTIMODE BS easy access cables are designed for fiber optic systems in high-rise buildings and multi-dwelling units (MDUs). MDUs are commercial or residential buildings with multiple offices or apartments, including "open space" solutions. The cables can also be successfully applied in old buildings with tight shafts, not allowing to use several cables. In this case, the use of the ULTIMODE Building System with easy access cables allows broadband service providers to build the distribution system much faster and easier.

We offer a range of ULTIMODE fiber optic distribution cables - with 12, 24, 36 and 48 single-mode fibers (G.652.D and G.657.A2)

ULTIMODE Building System is a solution to create FTTH networks in buildings (Fiber To The Home). The system provides a complete range of products for deployment of fiber optic links in each apartment/office, including "open space" offices.
