by Fiber-MART.COM Higher Bandwidth – longer range, better network speed Fibre optic cables  are made of glass threads which transmit data at the speed of light in glass (around 180,000 to 200,000 km/s…!). Because the speed of light is the fastest speed known, data is transmitted faster than via copper wires or cables.   Category 6A Cable (the standardized twisted pair cable for Ethernet) is classified by the Telecommunications Industry Association (TIA) to handle a bandwidth up to 600 MHz over 100 meters. Multimode Fibre, on the other hand, would have a bandwidth of over 1000 MHz.   The speed of transmission is limited by the endpoints, and not by the cable itself. Once you’ve installed fibre, you can increase your network speed simply by swapping out the endpoints.     Immunity to Electromagnetic interference Fibre optic cables are non-metallic. They transmit signals using pulses of light in glass threads as we explained above. As a result,...

by Fiber-MART.COM Optical Fibre Is Immune To EMI Fibre optic cables  are non-metallic... they transmit signals using pulses of light in glass threads! As a result, they are immune to Electro-Magnetic Interference and Radio Frequency Interference. In other terms, the integrity of signals is not affected by electrical noise in the environment.   In copper cables, the integrity of signals can be affected by electrical noise. This can also reduce speed of transmission as larger numbers of lost and/or corrupted data packets can lead to excessive levels of retransmission.   Attenuation loss can be as low as 0.2 dB/km in optical fibre cables, allowing transmission over long distances without the need for repeaters (than you will have with copper systems to ensure satisfactory performance over long distances with higher data rate).   Fibre connections isolate data from dangerous increases in ground potential, ground loops, and electrical EMI/RFI (radio-frequ...

by Fiber-MART.COM In the recent years, fiber optics is steadily replacing copper wires. It is a better and apt means of transmitting communication signals. Today, fiber optics cable span across long distances between local phone systems. In addition, it also serves as the backbone for many networking systems including:   Cable TV services University campus Office buildings Industrial plants Electric utility companies Internet connectivity Stereo systems Telephone systems   Fiber Optics Cable  use pulses of light to transfer data using the event of total internal reflection. The cable has a coating of plastic. This protects the cable from exposure to heat, cold, and other weather atrocities. It also protects the cable from electromagnetic interference and ultraviolet rays of sun. These cables are the most reliable and fastest data transfer cables on the planet.   A fiber optics cable system is very similar to the metal wire system. The fib...

by Fiber-MART.COM With speed in data center changing from 10- to 40-Gbps and eventually to 100-Gbps, mobile and virtualized workloads, cloud applications, big data and heterogeneous devices are all demanding previously unimagined capacity and performance from servers and data center fabric. High-capacity optical technology and cabling infrastructure are required to support those servers and applications for 40-Gbps upgrading. Today’s article will mainly introduce pluggable optical Enhanced Quad Small Form-Factor Pluggable (QSFP+) modules, especially Bidirectional and parallel QSFP+ transceivers.   Brief Introduction to Optical Transceiver The transceiver is an electronic device comprising both a transmitter and a receiver in the same circuity. This optical transceiver receives an electrical signal, converts it into a light signal, and launches the signal into a fiber. It also receives the light signal, from another transceiver, and converts it into an electrical signal. It...

by Fiber-MART.COM To back the changing and fast-growing bandwidth demands of data center, in 2010, the IEEE ratified 40 Gigabit and 100 Gigabit standards, known as IEEE 802.3ba. 40G and 100G Ethernet can be deployed using the same cabling systems today. Both single-mode (SMF) and multi-mode (OM3,OM4) were approved to be utilized in the standard. Multi-mode deploys parallel optics with MPO/MTP interconnects while single-mode fiber will employ serial transmission and use LC or SC connectors. Which cabling options designers should choose for their infrastructure. This article today will provide some practical suggestions to help you make a wise selection. Table 1 shows the comparison between SMF and MMF for 40/100 GbE Implementations.   40GbE Over Multi-mode Fiber 40GbE and 100GbE over multi-mode optics use parallel optics at 10Gbps lasers, simultaneously transmitting across multiple fiber strands to achieve high data rates. Because of the multi-lane nature of these optics, 4...

by Fiber-MART.COM When deploying a fiber network, people nowadays not only appreciate the high-speed broadband services, but the maintenance of how long it will last. After all, optical fiber is a particular type of hair-thin glass with a typical tensile strength that is less than half that of copper. Even though the fiber looks fragile and brittle, but if correctly processed, tested and used, it has proven to be immensely durable. With this in mind, there are essentially factors that will affect the longevity of your fiber network.   Installation Strains   Stress, on the other hand, is a major enemy of fiber longevity, so the protection task is passed to the cable installer, who will ensure that the use of suitable strength elements limits the stress applied to the cable to much less than the 1 per cent proof test level. The installer then needs to ensure that the deployment process does not overstrain the cable. Figure 2 below illustrates a typical crew deployment...

by Fiber-MART.COM 2018 is coming in less than a month, looking back, in the communication field, the old remaining dilemma between fiber and copper is still left behind. People are struggling about whether they should hold on to the tried-and-tested copper cables that are sufficient so far, or make the leap into the future, and go fiber optic. From a technical perspective, the case for switching to fiber is growing ever stronger. Using a fiber system will lead to more bandwidth, reliability, less down time and end up saving you money. Today’s article will make you understand the trend for switching to fiber.   More Bandwidth, Faster and Longer   People are aware that fiber optics is winning out over copper because of its higher performance, namely more bandwidth, faster speed and longer link distance.   Bandwidth decides how much data you can receive and send. Copper cable that can be used for 10 Gigabit cabling, and 100 Gigabit cables is at the point of to...
