HOME / Is the round cylinder a power cable or a fiber optic cable - DKN Access Networks & Consulting
Have you noticed that some power supply cables, especially new ones like your laptop power cable has a small cylindrical thing near the pin? They are always cylindrical but comes in different sizes. A lot of

The cylinder is called a ferrite bead, ferrite core, or, more generally, a choke. Cables can act like unintentional antennas, broadcasting electrical interference (“noise”) or picking it up.
Effectively, it is a thick-walled cylinder of iron ferrite that has been sliced down its axis to form two halves. The halves are in a plastic case that snaps around a cable, re-forming the cylinder.

What is the Tiny Cylinder? The tiny cylinder in power cords and cables is known as a ferrite choke, ferrite core, EMI filter, ferrite ring, ferrite block, or simply a ferrite
Can anyone tell me what the black pill/cylinder looking device is? Electric company is bringing 1Gbps fiber optic internet to my area, and I''m hoping to have it completely installed in the next month or two.
You can call that plastic cylinder a ferrite bead, a ferrite choke, EMI filter, ferrite core, or ferrite block. Whatever the name, it serves the same purpose.
Housing multiple pins or contacts for transferring electrical power, signals, or data, circular connectors are cylindrical electrical devices of varying sizes that are designed to withstand a range of
Circular connectors are cylindrical electrical devices of varying size with circular mating surfaces. They contain multiple pins, or contacts that connect with applicable parts to transfer electrical power,
Have you ever wondered why there was a bulky cylinder attached to the end of your laptop or mobile device charging cord? These cylinders are also common on keyboard cables as well.
Circular connectors are cylindrical interconnect devices designed to transmit electrical power, analog or digital signals, and data across multiple contact points. These connectors feature
Inside the cylinder on the cable is a ferrite core. The ferrite core acts as a filter that neutralizes the electromagnetic waves before they can be radiated over the cable. You can think of...
There''s always that pesky cylinder thing on every cable I have. What is it? And more importantly, why don''t Apple''s products have them?
To charge or power your everyday devices, you likely use a variety of cables. One thing you may have noticed about some of these cables, especially the ones you use to charge laptops,
It''s a "snowshoe" for fiber cables hanging on the stringer. Likely near a pole you''ll find a round plastic cylinder with fiber cables running on the stringer, down or up
My title describes the thing Boxes are about a foot tall and maybe 6 inches wide. Installed on utility poles. Many poles (100ft apart?) have the box. Every once in a while there is the added cylinder. All
The device comes with a power supply cable that has a cylinder connected at the end. We all are very well aware of the cables that are
You might have seen certain power or audio cables with a black cylinder near the end of the cord. What are these little things and what do they do?
Ferrite Beads are utilized in a number of ways, most notably at the end of some cables in order to filter EMI/RFI. They''re also used in data
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light.

Essentially, it "chokes" the RFI transmission at that point on the cable -- this is why you find the beads at the ends of the cables. Instead of traveling down the cable and transmitting, the RFI signals turn into
Because of this, power supplies are required to pass stringent tests on how much and what frequency noise they create. The common mode chokes you''re are designed to suppress electrical noise in the
The tiny cylinders in power cords and cables are referred to as ferrite cores (or) ferrite beads. These cylindrical components are constructed of ferrite, a magnetic ceramic. Ferrite cores
The ferrite acts as a wad of inductance, which works with the cable''s natural capacitance to form a low-pass filter. This is common on data cables and switching power supply cables to

I have noticed a large number of power cords that have a PSU built into them also have a second brick on them. What is the purpose of this "second power brick"? Example, Xbox 360 Power Adapter: I
