Local Area Network

When we go to work, we go to an office with the standard desk, chair, and computer setup. We print, fax, email, and make calls. It’s second nature, we don’t think about it, we just do it. We don’t really notice how it is that all of this is happening, that we’re on the same local area network, or LAN.

LANs are made up of 6 main components, the network workstations, interface cards and drivers, shared hardware resources, network operating systems, network-aware programs, and a communications medium.

Network workstations can range from anything to cheap low-end laptops and Chromebooks, to high-powered engineering workstations, to cell phones and tablets. As long as it’s able to handle the routine duties of accounting, word processing, point-of-sale, and so on, it can be counted as a workstation.

Network interface cards, or NIC, are what connects workstations into a network and allow them to communicate with each other and everything else on the LAN. Most computers have two built-in, one for Wi-Fi and one for ethernet. Drivers interpret the commands from your operating system into instructions that the NIC can read and understand.

Shared hardware resources are resources that can be shared on the LAN so that not every user on the network has to have their own. The biggest example of a shared network resource is the printer. The hubs, switches, and routers that connect the devices in the network are also included in this category.

Networking operating systems are software that keeps track of devices on the LAN, programs currently running, the information being circulated, and what resources are needed.

Network-aware programs are the working software most visible to users such as Word, Excel, Slack, Evernote, and security software. These can be accessed on the LAN or on the cloud.

Communication mediums are what connects all the devices on a LAN, whether the physical cabling or the virtual Wi-Fi connection. While cables transmit through electrical impulses, wireless LANs transmit through radio waves at either 2.4 GHz or 5 GHz frequencies.

It sounds like a lot sometimes, when we realize how much goes into the little things that we just use and take for granted. Fortunately, there’s Just Connectors, an ASAP Semiconductor proprietary website and the premier supplier of cable connectors and network components.

How does Fiber Optics Works
Fiber optics are long, glass strands that transmit light signals over long distances. The Fiber threads are as thin as a human hair and to make optical cables. The thin glass threads are bundled together so that they all work together to transfer light signals at a faster rate that has never been seen before. The Fiber Optics Cable has three parts. The first is the Core, the core is the bundled-up glass threads that carry the signal. The second, the Cladding, is a material that reflects the light signal back to the core to maintain maximum signal strength. The third and final component of a Fiber Optic Cable is the “Buffer Coating”. The Buffer Coating is a coating made of plastic that protects the rest of the components from damage or moisture.

The Fiber Optics works by utilizing 3 steps. A transmitter, optical regenerator and the optical receiver. The transmitter is very important because it makes it possible for the light signal to travel through the Fiber Cable. The transmitter focuses light into the glass threads in the cable to start the light transmitting process. The data is sent to the transmitter to focus the data trying to be transferred in the form of light and the transmitter focuses that light containing the data into the glass threads where it begins its transfer. Next the optical regenerator receives the data signal and boosts it so that the light signal makes it to its destination at full strength. Lastly, the optical receiver, which decodes the message and sends the light signal to whatever electronic device you are using so that the device can understand the data.

rg6-cables-benefits-and-key-features
RG6 cables, or radio guide cables, are a type of coaxial cable that are typically used for home and commercial purposes. These cables transmit audio and visual signals to devices like your television set via satellite dishes, cable television and aerial antennas.

These RG6 cables were first created for usage by the military as radio transmission equipment; however, according to a tech website called Tech-FAQ, it is reported they no longer serve such a function.  Once TV broadcasts and cable companies changed from analog to digital, there was a great need for a cable that would support satellite and internet signals, which ran at higher frequencies.

One of the reasons why RG6 cables are so popular, is because they oftentimes can completely replace RG-59 cables, which are essentially just older versions of coaxial video/audio cables.  These newer RG6 cables are more reliable due to their durability against interference and environmental wear and tear.  This feature allows the cables to be run underground and up building sides, making for an easier installation that doesn’t compromise quality.

Key features that make up the RG6 cable include:
  • Polyethylene cover – acts as a jacket, making the cable resistant to the elements
  • Shield layer– protects against any radio frequency interference
  • Locking nuts– go on the end of each cable to secure onto a jack, preventing accidental disconnection.
Some things to keep in mind when installing a RG6 cable:
  • The shorter the cable, the better.  A longer cable puts you at more of a risk of signal loss; even though the RG6 cable is more reliable and durable, it cannot completely protect against signal loss.
  • You may need to use a Crimp Terminal, or Crimper, to secure the connection.  Crimping the cable acts almost as a vacuum seal, which allows for an even better connection.?
Just Connectors offers complete supply chain management services to all customers– with a continuously increasing inventory, you can be sure Just Connectors will have everything you need and more.  Just Connectors will ensure all needs are addressed in a timely manner.  Just Connectors is known for having hard to find and/or out of stock parts and can always help you find cost-effective solutions.  For a quote, reach out to the main office by phone: 714-705-4780 or by email: sales@justconnectors.com

bnc-connectors
The Bayonet Neill Concelman connector, commonly referred to as a BNC connector, is a cable used in applications where coaxial or screened cable is required.  It is attached to the coaxial cable and are commonly used for connecting radio frequency signals or video signals on consumer electronics, aviation electronics, test equipment and military equipment.

The BNC connector is similar in function to a RCA connector, however the BNC typically has a more secure connection.  The BNC is more secure because it has snap-lock technology, which allows you to firmly lock it into place; this eliminates the possibility of disconnection if the cable is accidentally pulled on and assures a clearer signal to your television.
 
The BNC connector was first developed when the need arose for a high quality, sturdy connector that had multi-use capabilities.  Although BNCs are most commonly used in households as television cable connections, they can also be used for a wide range of other equipment including audio generators, avionics and power meters.
There are a few different BNC connector types:
  • Compression gland – requires no specialized tools to assemble
  • Crimp – requires greater accuracy when choosing the correct connector, because not all crimp types are practical for all cable sizes
  • Twist-on connector – only requires a cable stripper to assemble.
Here are some additional facts about BNC connectors:
  • Require a separate power source – power cords were originally included but they were too bulky and made the BNC not as universal
  • Can transmit videos but don’t support any audio – sometimes results in the need for an additional audio connector
  • Applied to frequencies below 3GHz and voltages below 500v
  • Come in 50 and75 ohm versions

hirose df58 series connector

Hirose has announced the release of the DF58 series for miniature applications. This wire-to board connectivity will deliver a space saving solution in a range that will consist of crimp sockets and headers lined up in a single row. The space on the board is shortened to 1.00 mm for the height and 4.97 mm for the depth.

This helps keep the DF58 compact and efficient. The small size of the connector does not compromise the power rating. It can still reach a high current rating of 3A, which will support power supply applications. This will occur while using the 2-contract version of 28AWG cable. The DF58 series has a high current secure connection with double locking mechanism, possible with ViSe, the vertical-insertion swing-extraction.

A secure lock is created when the socket is mated to the header in a vertical direction, and then guided to an angle to create the positive lock. This allows a force to prevent the cables from disconnecting and remain undisturbed. This works better than other comparable tools, which generate incomplete locking or floating when there is not enough friction and force that lock the cables properly.

The DF58 series comes with a highly efficient 2-point clipping contact, which is used for stabilizing and reducing any rise in temperature. Key features include contact positions, 2, 3, 4, 6, a contact pitch of 1.2 mm, a current rating of 3.0A (2 contact version 28AWG cable, voltage rating of AC/DC 100V, mating cycle of 10, and Cable size of AWG 28-30.

This solution will serve many different types of applications, including wearable devices, drones, medical equipment, digital cameras, and other types of portable applications.

Molex claims they are the smallest fully isolated terminal power connectors on the market—up to 69% smaller than competitive products. Fully protect your terminal headers and gain terminal position assurance with the new Molex connectors.

Those in power application often come to the dilemma of deciding between exposed power terminals that risk damage to connectors or large, isolated headers that take up valuable space. Molex compact Nano-fit power connectors offer space saving and isolation in a single product design. It’s always important to consider the trade-off between isolated headers and shrouded pin field contacts when designing circuit boards.  Shrouded pin fields can save space but have the tendency of shorting and will need replacement over time. Isolated headers give the user security with increased protection as well as 4 points of contact. This redundancy gives secondary current paths that guarantee long term reliability and performance. The Molex Nano fit power connector compact headers will save space while also shielding any exposed terminals, giving engineers confidence in the design of their compact printed circuit boards.

The low mate force headers reduce user fatigue and an audible click give ensures terminal contact. Multiple color options give easy visual ques to users and a variety of mechanical keying options can prevent assemblers from cross mating headers. Take advantage of visual ques to save yourself time and money. There is no need to deal with the headache of counting terminal pins to make sure you are using the correct shroud. The optional terminal position assurance (TPA) feature ensures terminals are fully seated in their housing to effectively eliminate terminal blackout. These power connectors are available in through hole and surface mounted termination styles. Terminals are RoHS compliant and halogen free.
