Radiotechnika Marketing cooperates with a number of optical fiber cables manufactures including the most significant partner Optical Cable Corporation (USA). All of our cooperators produce not only special application cables but also typical IT application optical fiber cables. In each of the cable types offered, we are able to provide high-quality optical fibers by world's leading potentates tailored to the needs of our customers and the requirements of modern information systems. Both single-mode fiber (SM) and multimode (MM) of different kind and type: (B1.1, B1.2, B1.3, B2, B4, OM1, OM2, OM3, etc.) may be used in each cable.
In order to better assist you with choosing the cable that best suits your needs, please refer to the basic groups of dry cables:

Patchcord cables:
is the simplest form of fiber-optic cable designed for indoor use. Patchcord cable consists of an optical fiber coated with tight buffer which is wrapped with aramid yarns encased by outer jacket usually made of halogen-free material. Such a cable can be produced either as simplex or duplex. Its outer diameter depends on the type of connectors to be installed on the cable and can range from 2 to 3mm. We also provide cables for SFF patchcord connectors (such as MT-RJ) with 2x1,6mm outer diameter and „8” cross section with the fiber in the buffer of 600μm or with circular cross section and a diameter of 2.9 mm with the fiber in a buffer of 900μm.

Distribution Cables:
these cables are highly versatile. They can serve as a trunk line cables between buildings as well as connect data communication equipment installed on different floors of the same building. They occur both indoor and outdoor (armor may be metal or dielectric). Few to tens of fibers, each in their own tight tube (buffer) are wrapped with aramid fiber ensuring mechanical resistance. The whole is covered with a jackt to which an outer protective armor can be applied optionally. The optional armor can be made of corrugated steel tape or glass fibers. This cable allows direct installation of the fiber optic connectors on the buffer of 900μm. In comparison to gelled cables it significantly increases system reliability, simplifies cable mounting in the connection rack, reduces the time required for installation and installation costs.

Breakout Cable:
These cables resemble in their structure a harness of simplex fiber optic cables enclosed in a common jacket. The fiber optic fibers in such cables are best protected (such cables have the highest mechanical resistance) but it causes an increase in cable diameter and weight. They are available with metal or dielectric armor (similarly to distribution cables). This kind of cable structure allows for elimination of much of the patch cord connection as each fiber protected by its own jacket and aramid yarns can be brought directly to the active device of optical network. The sub-cable allows direct connection with connectors identical to those used in patch cords.

Subgrouping Cable:
these cables are harnesses of distribution cables enclose in common jacket. Ideal for intermediate solutions where connecting devices located in different cabinets / racks is required. Each rack can then have its own distribution cable. This increases the clarity of connections and thus improves network serviceability. This is a convenient choice for installations where parallel fibers SM and MM fibers are used. They are available in indoor and outdoor versions and can have additional metal or dielectric armor.

Figure-8 with supporting wire:
These cables are used for aerial connection between buildings. Their cross-section resembles number "8" where one part is a supporting wire (steel or dielectric), while the other part is a fiber optic cable with a distribution structure. Their special characteristic is a jacket made of material resistant to ultraviolet radiation. Special slings automatically locking (clamping) on a wire due to force of gravity are available for cables of this type.

Self-supporting cable:
Application of these cables is identical to the cables with supporting wire. The structure of these cable is almost identical to the distribution cables. They are distinguished by a large number of aramid yarns that provides great tensile strength. They are fully dielectric and very flexible.

Furcation tubing:
They are used where it is necessary to protect the separate fibers of both loose-tube and tight buffer optic cables furcated at ends. We offer tubings for both fiber with acrylic coating (250μm) with buffer (900μm) and the ribbon fiber.
The tubing is made in the form of tubes with an internal diameter of 450μm (900μm external) or internal 1100μm (external 1500μm) wrapped with aramid yarns and protected by a jacket. Tubing resembles patchcord cable (simplex or duplex) out of which the fiber has been drawn.
For ribbon fibers the tube has a rectangular cross section and can take up to 12 optical fibers.
