The list of antonyms for ‘amplify’ includes words like ‘decrease’, ‘weaken’, ‘diminish’, ‘reduce’, etc. So, if you were looking for something to do the opposite of fibre optic amplify a signal, you might be tempted to look for something along the lines of a ‘diminisher’ or ‘anti-amplifier’— and if you asked for help looking for those things, you’d probably get some weird looks thrown your way. Fortunately, that’s not the case because what you’re looking for is actually called an ‘Attenuator’.

Attenuators are the effective opposite of amplifiers; they reduce the power connector of a signal without appreciably distorting the waveform and provides loss instead of gain. For optical signals, there’s the fiber optic attenuator, useful for when an optical signal is too strong to work with things like multi-wavelength systems or optical receivers with certain input specifications. Fiber optic attenuators are also common in fire optic communications applications where they test power level margins by temporarily adding a calibrated amount of signal loss, or by being installed permanently to properly match transmitter and receiver levels.

Attenuators interconnect typically all have male and female ends, but double-female end attenuators are also available. There are two basic types of fiber optic attenuators: fixed and variable. Within the category of fixed attenuators, there are built-out or in-line patch cord styles. And within the category of built-out cord styles, there are air gap attenuators and doped fiber attenuators.

Air gap attenuators create a loss of optical strength with the help of two fibers that are separated by air to yield the loss. They can be fixed or variable, which makes them a slightly more versatile option. However, they’re incredibly susceptible to dust contamination, changes to temperature, and moisture; they also tend to create second order distortions that reduce performance.

On the other hand, doped fiber attenuators create a loss of optical strength with the help of a small fiber piece along with metal ion doping to provide precise attenuation and interfacing in between male and female connections. Doped fiber attenuators are better than air gap attenuators in that they are not susceptible to dirt, changes in temperature, or moisture, and they are able to provide solid and stable performance over wide wavelength variations and band passes, but they are slightly more expensive as a result. Either way, you have options to consider and choose from, other than ‘anti-amplifier’.

When it comes to electrical equipment and circuits, one of the most important components is the circuit breaker. A circuit breaker is a switching device that disrupts an abnormal or faults current. It is a mechanical device that interrupts the flow of high magnitude current while also acting as a switch. A norsense electronic circuit breaker is primarily designed to close or open an electrical circuit connector, which in turn, protects the electrical system from damage.

                A circuit breaker consists of both fixed and moving contacts. When the circuit is closed, the contacts touch each other and carry the current under normal conditions. In this state, the electrodes, which are the current carrying contacts, interact under the pressure of the spring. In normal conditions, the circuit breaker’s arms can be either closed or opened for switching regulator and maintenance of the system. To open the circuit breaker, just apply pressure to the trigger. This allows it to easily deal with things such as overloads and short circuits.

When the circuit detects a fault, previously stored mechanical energy, or even the higher current itself, is used to separate the contacts. When the fault is cleared, the contacts can be closed again to restore power to the circuit.

                There are many different types of circuit breakers. This includes, but is not limited to, the following: oil circuit breaker, minimum oil circuit breaker, air blast circuit breaker, Sulphur hexafluoride circuit breaker, vacuum circuit breaker, and air break circuit breaker. Most often, circuit breakers are arranged based on rated current voltages. Circuit breakers below 1000 volts are identified as the low voltage circuit breakers, and circuit breakers above 1000 volts are identified as high voltage circuit breakers.

                Just Connectors, owned and operated by ASAP Semiconductor, was designed to streamline the parts purchasing process. Under the Micro-Electronics Division of ASAP Semiconductor, buyers can search for over 2 billion different part numbers.

RS-485 cables are the standard in the connector cable industry, they are used for serial communications. These communications are possible because of two lines that are dedicated to a differential pair and one as a reference. It’s important to note when building with the standard, build the network with 32 slave devices connected to one master; this ratio ensures balance in the communication network. Also known as TIA/E1A-485(-A), this standard is suitable in noisy industrial environments where the application doesn’t require high transfer rates driving multiple devices.
RS-485 cables configurations can support multiple protocols. Sometimes they might not be working at the same time, but they are consistently using the same protocol for the device's network. When considering the selection of an RS-485 transceiver, make sure you know how many devices you need so that you can determine if you will need one master or need additional masters.
This will help with any network lag that may exist. A second major consideration is whether you need full or half “duplex”. The difference between the two is that the full duplex can both send and receive information, while the half-duplex is only able to send or receive— it does not have the ability to do both. Additionally, the distance of the master greatly affects the speeds of the network.
RS-485 cables can handle up to 100 Mbps. This allows the RS-485 to be most suitable in actuators, card readers, building automation controls, video surveillance, security control panels, and even for Digital Power Control (DPC). RS-485 cables are highly reliable due to integrated pre-emphasis circuitry, which extends through the entire length of the cable, helping with long distance integrity.
For all your RS-485 cables, signal connectors, and ESD and transient voltage, needs make sure to visit us at Just Connectors, owned and operated by ASAP Semiconductor. We will be able to provide you with the connectors you need as soon as possible and at the most competitive price on the market.

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.

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, 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

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 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.
