The light traveling the optical fiber is the main carrier of information or data that needs to be transmitted along the fiber optical cable. In order to receive the useful data without the errors the system has to receive the light at an optimal optical attenuation level. Either too little or too much power will cause high bit error rates. The Bit Error Rate (also BER) is the number of bit errors per unit time. The bit error ratio is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit error ratio is a unitless performance measure, often expressed as a percentage.

Today, Fiber Optic Networks rely on optical transceivers to send the optical light down the optical cable. These optical transceivers come in many form-factors and types. They are modules that transmit and receive optical data using incorporated lasers.

In recent years it has become apparent that fiber patch cords are slowly but surely replacing copper wires. This is mainly because of their bandwidth and distance capabilities. They can reach up to 160 kilometers in distance and they can support the network backbone. The fiber patch cord is similar to the copper cables. The main difference is that instead of transmitting electrical impulse, the fiber patch cord transmits optical light and with the help of optical equipment this light is then converted in electrical input.

Ethernet technology is the one that transformed our world and our lives. As of today, Ethernet is the most dominant networking protocol. Of all existing networking and communication protocols, Ethernet has the highest number of installed active ports, by far. It all started with 10 Mbps, and by the mid of the '90s, we had 100Base Fast Ethernet available.

Have you heard the latest news today? It says that a product in the European Union (EU) was assembled with components, thought to be from within the EU, but it may actually be a counterfeit!

As the demand for simpler and more secure network architectures grows, Datacenters must find a solution to accommodate the large number of devices and at the same time deploy a cost-effective solution. The key extension component of a data center that saves money on the long run and that would provide a stable and easier to maintain and upgrade data center networks are Direct Attach Cables. Because networks and the demand for high bandwidth components are growing, Direct Attach Cables emerged as the optimal solution to support this.

The fact that 40 GB Ethernet is slowly being replaced by the 100 GB is undeniable. From day to day more and more leading IT and telecommunications vendors are trying to seize the opportunity to launch their own 100 GB Ethernet solutions. 100 GB Ethernet is the latest technology which provides a stable ground for future high bandwidth requiring applications.

Since Active Optical Cables (AOC) and Direct Attach Cables (DAC) are a alteration of optical transceiver, they are used to connect switches with one another when creating a stack or switches to routers or servers. A Direct Attach Cable (DAC) can be produced as passive or active variant. As the passive DAC has no active components, it offers a direct electrical connection between corresponding cable ends. This method can also be completed by an active DAC, which is considered active because there are extra electronics embedded inside the connectors. Therefore it helps to advance signal quality, offering a longer cable distance. The DAC is a fixed assembly that can be bought in several lengths for short distances of up to 15 Meter.

The manufacturer of network products CBO, announces its new partnership with the distributor reichelt elektronik. As an addition to the extensive portfolio of reichelt elektronik, BlueOptics and BlueLAN products have now been introduced, which are now available through the distribution channels of the new partner.

Dense Wavelength Division Multiplexing or DWDM is one of the two methods used for wavelength division multiplexing in fiber optic communications, the other being coarse wavelength division multiplexing or CWDM. Wavelength division multiplexing is a technique which multiplexes several optical signals onto a fiber optic cable by using different wavelengths of the light.
