Tight-buffered distribution cable consists of several tight-buffered fibers consolidated in a single cable. It is usually used in backbone subsystems, linking equipment rooms, telecommunications rooms and outlets. According to different application environments and requirements, there are various types of tight-buffered distribution cables available in the market. This post intends to give a selection guide for tight-buffered distribution cables.
Tight-buffered distribution cable is ideally suited for indoor-cable runs. But it is also available to use for indoor/outdoor applications by adding some specific cable characteristics (will introduce in details in section 3). When choosing the tight-buffered distribution cable for indoor application, we should consider the flame ratings that are governed by the NEC (National Electric Code). Flame ratings generally include plenum, riser, general, etc., as shown in the following picture:
Among these different rating cables, plenum can also be used in riser and general space. Riser cable is also used in general space. But the higher the rating, the more expensive it costs. Thus, users can choose the relevant rating or higher rating cable according to their application space and budget.
Fiber type and fiber count are two main factors that should be considered when choose tight-buffered distribution cables. Fiber type generally includes OS2 9/125 SMF, OM1 62.5/125 MMF, OM2 50/125 MMF, 10G OM3 50/125 MMF, 10G OM4 50/125 MMF which meet the applications of single-mode, multi-mode and 10G multimode fiber cabling. Once the fiber type is determined, to choose a proper fiber count is also important. Fiber counts are generally available in 1 fiber to 24 fibers, sometimes can be larger than 24 fibers. 2, 6, 12, 24 fibers are the most commonly used fiber counts in today’s network backbone cabling. The fiber count should be sized to deliver present and future applications.
Sometimes, in order to meet the requirements of harsh indoor/outdoor environment or installation & management, tight-buffered distribution cable is designed with some specific characteristics, as mentioned above. For instance, armored layer is added to the tight-buffered distribution cable to prevent cable from moisture and rodent chewing. Popular armored types include interlocking armored and corrugated steel tape. Unitized tight-buffered distribution cable is preferred to use as it can make the bundled fibers easier to install and manage. Thus, users can choose the characteristics—armored or non-armored; unitized or non-unitized depending on their requirements.
