Application of optical communication is still broad prospects

Once the Nortel global leader in fiber optic communications during the Internet bubble in 2000, the money in the acquisition of a large number of optical communications research and the production of small and medium enterprises, the industry has been criticized in the subsequent bankruptcy of Nortel. In fact, Nortel grasp of technology trends, the direction is right, unfortunately, Nortel too hasty, global demand for optical communication was not to such an extent.

But now the situation is very different compared with around 2000. The rapid development of mobile Internet and the widespread popularity of smart mobile terminal equipment, being a huge challenge to the global telecommunications network capacity, transmission speed. The era of “data flood peak to optical communication technology has always been known by the transmission bit of new development opportunities and a huge space. Optical communication technology not only did not fall behind, the contrary, the optical communication industry chain, from fiber optic cable system equipment, terminal equipment to optical devices, a critical period in the comprehensive technology upgrade.

The field of optical communication is a noteworthy event, the National Development and Reform Commission recently organizing the preparation of strategic emerging industries key products and services Guidance Catalogue, which in conjunction with the relevant departments, the optical communication technology and product responsibility and selected emerging industries of strategic focus products.

In fiber optics, including FTTx G.657 optical fiber, broadband long-distance high speed large capacity optical fiber transmission with G.656 optical fiber, photonic crystal fiber, rare earth doped fiber (including ytterbium doped fiber, erbium doped fiber and thulium doped fiber, etc.) the laser energy transmission fiber, and has some special properties of new optical fiber, plastic optical fiber, polymer optical fiber is fully finalists. The upgrade of the fiber optic technology, will bring the data transmission capacity, distance, quality leap.

In the field of fiber access equipment, passive optical network (PON), wavelength division multiplexer (WDM),OLT and ONU on the list. Optical transmission equipment, especially the line rate of 40 Gbit/s, 100Gbit/s large capacity (1.6Tb/s and abobe) DWDM equipment, reconfigurable optical bifurcation Multiplexer (ROADM) wavelength division multiplexing system ran cross-connect (OXC) equipment, large-capacity high-speed OTN optical transport network equipment as well as packetized enhanced OTN equipment, PTN packet transport network equipment also impressively. These products are “broadband China” works to promote a powerful weapon; both long-distance backbone network, metropolitan area network or access network even close to the user’s “last mile” of these products will come in handy.

The major products are classified as strategic emerging industries in the field of optical devices, high-speed optical components (active and passive). This is the core and foundation of the field of optical communication technology, device development, the improvement of integration, function enhancement can bring significantly reduce the cost of system equipment and provide a performance boost.

At the same time, the annual OFC / NFOEC (fiber-optic communications exhibition) will be held in late March in California. This event will showcase the latest technology and research progress of the global optical component modules, systems, networks and fiber optic products, represents a new trend of development of optical communication technology.

100G for ultra-high-speed network technology is the current OFC hot one. 2012 100G technology on a global scale backbone network level scale application of 100G optical network applications will rapidly expand with the 100G device further mature. In the same time, the industry has also increased efforts to develop the 100G optical modules, silicon photonics technology pluggable multi-source agreement 100G CFP MSA CPAK optical module has been available. Outside the backbone network, 100G MAN application is the current one of OFC discussion topic.

The rise of cloud computing brings data center construction boom, 100G technology in the data center is a popular data center for high-speed pluggable optical devices is also a hot topic. Experts believe that photonic technology has a key role to play in the large enterprise data centers, but this is only a start, the size of the new cloud computing data center such as a warehouse, with more than 100,000 servers carrying the computing and storage resources, the required network bandwidth than PB level. These data centers only optical communications technology in order to achieve VCSEL (vertical cavity surface emitting lasers) and multi-mode fiber has played an important role, and will continue to introduce new fiber optic communication technology.

The Application of Fiber Optic Connector

fiber optic connectorFiber Optic Connector has been widely used in fiber optic transmission lines, fiber optic patch panels and fiber-optic test instruments and meters. The Fiber Connector is one of the most essential components for fiber optic communication. It mate or connect with optical devices, modules, and fibers. Fiber connector is also the key part used in fiber Patch cord and fiber Pigtail.

In fiber optics design, when the system is capable of normal operation, if you are trying to build the local network or LAN in your home then you most probably know you will need a fiber patch cable and may be a hub or we achieved a very good results. Choosing a good fiber optic modem depends on a few factors, including availability. We need to consider not only some unexpected problems appear in the system design, but also expect the system to achieve the effect of normal operation. During the process of system design, we have to consider the worst case appear and related plans, is looking forward to improved operating results. In system design, security, stability and system access request the end of the fiber is smooth, neat. The connection between the clients must be accurate, micron accuracy or millionths of a meter. The diameter of the commonly used multi-mode fiber is from 50 to 62.5 microns, while the diameter of the single-mode fiber is only 8-9 microns. This size of the diameter of a human hair can (17-180 microns) are compared in diameter, and we can make sure that every trace of error can bring catastrophic losses.

With the expansion of technology development and application of fiber optic patch cables are also achieving rapid development. The types of fiber optic connectors on the market are probably 12 or more, each of which was launched to the specific needs, of course, came to meet, there are some technical limitations. The trend in the market is developing at a moderate price, compact plug-mode and all can support the requirements of the new transmission distribution system. As users expect that the ongoing development of the telecommunications industry also supports the large-scale application of the optical fiber, in large part due to the rapid growth of demand in the way of communication and entertainment services on the fiber link.

The fiber optic connection is very stringent accuracy of the equipment, the species of fiber patch cords are many kinds. So the connector must be very clean. Fiber optic connectors and accessories are usually mounted on a series of house, a fingerprint or external dust seriously affect the performance of the connector, and even the loss of communication. Therefore, the connector can be stored in clean protective sleeve without connection. Then we should also put fiber optic connector.

Fiber optic connectors according to the different transmission media can be divided into common silicon-based optical fiber single-mode and multimode connectors, as well as other issues such as plastic and as the transmission medium of optical fiber connector; connector structure can be divided into: FC SC, ST, LC, D4, DIN, MU, the MT and so on in various forms. The optical interface is the physical interface used to connect fiber optic cable. FiberStore as the main professional fiber optic products manufacturer in china offer a various kinds of fiber optic connectors, FC Connectors, LC Connectors, SC Connectors, ST Connectors. You can buy fiber optic connection products on our store with your confidence. All of fiber optics supplies with high quality but low price.

What is a fiber optic coupler?

Fiber optic coupler is used to split the fiber optic light into several parts at a certain ratio. fiber optic coupler are important passive components used in FTTX networks. A fiber-optic splitter is a device that takes a single fiber optics signal and divides it into multiple signals. Fiber optic is a type of technology that uses an optical signal instead of an electrical one to send data from one place to another. The cable is made either of glass or plastic coated in plastic, instead of the copper wire that was commonly used in the past. But two kinds of fiber splitters are popular used, one is the traditional fused type fiber optic coupler (FBT coupler), which features competitive prices; the other is PLC fiber optic coupler, which is compact size and suit for density applications. Both of them have its advantages to suit for different requirement. The use of fiber optic technology has become increasingly popular for several reasons. Fiber optic cables are much less sensitive to electrical interference, marking them more reliable than older types of cabling. They are also able to carry very large amounts of data in comparison with that older systems can handle. This makes them very efficient, despite the facts that there are some drawbacks to the system. The cables  require a thicker covering to protect the optical cables and they also need to have repeaters installed to boost the signal strength in order for the system to work, two hindrances to the use of this technology.

Despite the limitations, fiber optics technology is in use for both home and commercial applications. The most common type of fiber optic coupler splits the output evenly, with half the signal going to one leg of the output and half going to the other. It’s possible to get splitters that use a different split ratio, putting a larger amount of the signal to one side of the splitter than the other. The Splitters are identified with a number that represents the signal division, such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other.

Some types of the fiber optic coupler are actually able to work in either direction. This means that if the device is installed in one way, it acts as a splitter and divides the incoming signal into two parts, sending out two separate outputs. If it is installed in reverse, it acts as a coupler, taking two incoming signals and combing them into a single output. Not every fiber optic coupler can be used this way, but those that can are labeled as reversible or as coupler/splitters.

FTTx: fiber to the home/Premises/Curb

FTTx: fiber to the home/Premises/Curb

CATV companies are considering fiber to replace coax, since the cost is reasonable and performance unlimited. Municipalities or private individuals are looking at installing their own FTTH systems when phone or CATV companies won’t do it soon enough. Housing developers are learning about FTTH because their customers are demanding the highest bandwidth broadband connections.   DK Photonics

All these plans depend on finding or training adequate numbers of technicians. The FOA, working with operating companies, municipalities, installers and our approved schools has developed requirements for FTTx training and certification, with the goal of providing enough qualified FTTx installation technicians to make these plans possible.

FOA CFOS/H Certified FTTH Technician certification programs are now being introduced in many FOA-approved schools. Students seeking certification must complete the FOA CFOT program first to obtain their first level certification, then attend a short course on FTTx that will prepare them for the CFOS/H exam. Those interested in learning about FTTx but are not seeking certification will find the courses good information on the current technology.
