Black Box Explains... Fan-out kits.

Furcating is the process of adding protective tubing to each fiber within a loose-tube cable. It can be a headache-inducing task if you don’t have the right tools. If you... more/see it nowbend the cable or buffer tubes past their recommended bend radius, or if you allow them to kink, you’ll end up with substandard cable connections and splices that can break down over time. And, if the cable is outdoors, it can become exposed to the elements. The end result: a damaged cable without optimal transmission performance.

That’s why a fan-out kit is an absolute must during furcation. These kits enable you to branch out the fragile fiber strands from a buffer tube into protective tubing so you can add a connector. And, you can do it without using splicing hardware, trays, and pigtails.

To separate the fibers, use the kit’s fan-out assembly, which is color-coded to match the fiber color scheme. The assembly protects the cable’s bend radius. It also eliminates excessive strain on the fibers by isolating them from tensile forces.

Several types of fan-out kits are available for both indoor and outdoor cross-connects. The outdoor kits include components that compensate for wider temperature fluctuations. Some kits are used to terminate loose-tube cables with 6 or 12 fibers per buffer tube. Others enable you to furcate and terminate more than 200 loose-tube cable fibers, sealing the cable sheath and providing a moisture barrier at the point of termination. These kits require no additional hardware.

Although it’s recommended that you terminate loose-tube cable at a patch panel, that might not always be possible. For this, there are “spider“ type fan-out kits, which affix a stronger tubing to the bare fiber. The tubing is typically multilayered, consisting of a FEP inner tube that holds the individual fiber, an aramid yarn strength member, and an outer protective PVC jacket. Once you strip back the cable jacket, you thread the fibers into the fan-out inserts. collapse

Black Box Explains...Coax connectors.

The BNC (Bayonet-Neill-Concelman) connector is the most commonly used coax connector. This large ”bayonet“ connector features a slotted outer conductor and an inner plastic dielectric, and it offers easy connection... more/see it nowand disconnection. After insertion, the plug is turned, tightening the pins in the socket. It is widely used in video and Radio Frequency (RF) applications up to 2.4 GHz. It is also common in 10BASE2 Ethernet networks, on cable interconnections, network cards, and test equipment.

The TNC connector is a threaded version of the BNC connector. It works in frequencies up to 12 GHz. It‘s commonly used in cellular telephone RF/antenna applications.

The N connector is a larger, threaded connector that was designed in the 1940s for military systems operating at less than 5 GHz. In the 1960s, improvements raised performance to 12 GHz. The connector features an internal gasket and is hand tightened. It is common on 2.4-GHz antennas.

The UHF connector looks like a coarse-threaded, big center-conductor version of the N connector. It was developed in the 1930s. It is suitable for use up to 200–300 MHz and generally offers nonconstant impedance.

The F connector is most often used in cable and satellite TV and antenna applications; and it performs well at high frequencies. The connector has a 3/8–32 coupling thread. Some F connectors are also available in a screw-on style.

The SMA (Subminiature A) connector is one of the most common RF/microwave connectors. This small, threaded connector is used on small cables that won’t be connected and disconnected often. It’s designed for use to 12.4 GHz, but works well at 18, and sometimes even up to 24 GHz. This connector is often used in avionics, radar, and microwave communications.

The SMC (Subminiature C) connector is a small, screw-on version of the SMA. It uses a 10–32 threaded interface and can be used in frequencies up to 10 GHz. This connector is used primarily in microwave environments.

The SMB (Subminiature B) connector is a small version of the SMC connector. It was developed in the 1960s and features a snap-on coupling for fast connections. It features a self-centering outer spring and overlapping dielectric. It is rated from 2–4 GHZ, but can possibly work up to 10 GHz.

The MCX (Micro Coax) connector is a coax RF connector developed in the 1980s. It has a snap-on interface and uses the same inner contact and insulator as the SMB connector but is 30% smaller. It can be used in broadband applications up to 6 GHz. collapse
