Portugal Telecom demos 100 Gbps over its optical fiber network

Portugal Telecom has demonstrated a 100-Gbps connection between Lisbon and Oporto using equipment from Alcatel-Lucent (Euronext Paris and NYSE: ALU). So this is about the entire world’s communications. very important. So lets start with what is the optical fiber.

From wikii, An optical fiber is a thin, flexible, transparent fiber that acts as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics.

The demonstration showcased end-to-end optical/IP 100-Gbps connectivity across an existing active DWDM link covering more than 400 km. The link used Alcatel-Lucent’s 1626 Light Manager enhanced with 100G coherent technology and the Alcatel-Lucent 7750 Service Router equipped with 100 Gigabit Ethernet cards for IP/MPLS routing and services..

“In keeping with industry trends, we’re expecting that video will account for well over half of our consumer traffic. This kind of demand requires higher-speed, higher-capacity technology,” said Alfredo Baptista, Portugal Telecom CTO. “This fully integrated IP/optical 100G connection, together with the previously announced evolution of our fiber access network with GPON and 10GPON technologies [see "Portugal Telecom, Alcatel-Lucent to trial symmetrical 10G GPON"], is one further step towards a Next Generation Network with full end-to-end IP connectivity with high quality standards and very high speeds, being these unique characteristics not replicable on other type of technologies.

Portugal Telecom recently reaffirmed its commitment to invest in its optical fiber splicer network to the customer home with the objective of covering another 600,000 houses in addition to the over 1 million homes already serviced by the network. The network expansion will use about 300,000 km of fiber and shall involve approximately 1500 people between PT collaborators and external suppliers. Once complete, PT’s fiber network will reach over 50% of homes in Portugal.

“The upgrading of service provider networks to 100G will be a major focus and business area for several years to come and these speeds will become the new currency of IP and optical networks,” said Adolfo Hernandez, president of Alcatel-Lucent’s activities in EMEA. “This demonstration brings to light the years of investment PT has made on future proof optical and IP infrastructure which is compatible with today’s 100G technology.”

The Optical Fiber Communication Conference and Exposition (OFC) and The National Fiber Optic Engineers Conference (NFOEC) in 2009 promises to be the most exciting in recent memory featuring technology from around the world and every sector of optical communications. The conference and exposition are the foundation of the optical communications industry and bring together the people, products and information that drive technology.

1. Full Service Broadband The rapid development of broadband is dramatically changing the way people’s daily lives and the telecommunications industry, operational and business models. In daily life, based on broadband technology, entertainment video and audio content, online games, virtual communities to share multimedia information services such as information dissemination is being more widely used, to provide people with more wealth and convenient way of life; and for telecommunications industry, the traditional single of voice-based business model, or to provide for Web browsing, e-mail, and other simple Internet access to bandwidth-based delivery model, is rapidly converged multimedia applications to provide full service business model development. The future will be a broadband everywhere in the world: the user needs to be able at any screen (including computers, televisions, mobile phones and other devices) at any time to enjoy a variety of integration of broadband multimedia services. Full Service Broadband not only meet the end consumer quest for convenience, but also helps operators improve customer loyalty, attract new customers, create new revenue streams. With the era of full-service integration, application will be an unprecedented wealth. Including high-definition IPTV and other multimedia services, including a variety of value-added, will become an important source of revenue carriers, also bound to full-service broadband operators to build new demands on the network. Ericsson optimistic about the great prospects of full service broadband, through a series of acquisitions to strengthen the fixed-line broadband and multimedia applications on the layout, customized for operators of full-service fixed-mobile convergence solutions for broadband networks. Since 2005, Ericsson has acquired Entrisphere, Marconi, Redback, TandbergTelevision have lead in their respective fields such as technology and products company, building from the access, metro, aggregation, core-to-end application of the fixed broadband network solution program. 2.GPON optical access As a full-service broadband network, an important part of broadband access network is undergoing profound changes. On the one hand, xDSL technology gradually from ADSL \ ADSL2 \ ADSL2 +, etc. to be able to provide higher bandwidth VDSL2 upgrade, which also requires VDSL2DSLAM more close to the user side. VDSL2 was game point with the increase in magnitude, also proposed the clustering of high DSLAM requirements; the other hand, twisted-pair technology provides the bandwidth, access range, and many natural defects, optical fiber is rapidly replacing copper wire an ideal medium access. Major domestic fixed-line broadband access network operators to keep up with trends, are presented “DSLAM Down” and “Light of Copper” strategy, in order to meet the full-service broadband network development requirements specified in the right direction. GPON (GigabitPassiveOpticalNetwork, Gigabit Passive Optical Network) fiber access technology is to provide operators with carrier-class full-service broadband access network solutions for the right moment. GPON technology is based on standard ITU-TG.984.x the latest generation of broadband passive optical network access technology, high bandwidth, high efficiency, multi-service unified support, good interoperability and manageability of the many advantages , is being more and more mainstream operators as building the ideal full-service broadband network technology. GPON first organized by the FSAN made in September 2002, ITU-T on this basis was completed in March 2003 and G.984.2 ITU-TG.984.1 formulation, in February 2004 and in June completed G.984.3 and G.984.4 standardized, and ultimately formed a family of GPON standards. GPON supports single-fiber downlink rate of 2500Mbps and 1250Mbps uplink. Utilization rate of about 92% to single fiber can provide effective bandwidth is much higher than xDSL and other optical fiber access technology, can better support such as high definition IPTV, video-on-demand high-bandwidth applications.

Plastic Optical fibers and Its large potential in Optical Communication

Article by Carnellia Roupe

Since the inception of lightwave optical relationship with fiber, the concentrate is becoming for the technology for long-distance telecommunication applications. And that is why individual mode goblet optical fibers is becoming probably the most favored channels for this kind of applications.

Because in the ever-increasing need for just about any whole whole lot more bandwidth, the information relationship marketplace has risen toward forefront in fibers optic communication. subsequent many rounds of competing with other technologies, Ethernet is definitely the winner for LAN networks.

Silica-based multimode fibers is adopted to provide an affordable optical website link using a mixture of transceivers dependent on Vertical Cavity Surface-Emitting Laser (VCSELs).

However it is not probably the most effective option to distribute this kind of the silica-based optical fibers even in premises and residence systems or interconnections.

Why? plastic material optical fibers (POF), with its its huge core, is becoming anticipated for getting the business office and residence neighborhood media. plastic material optical fiber’s huge middle permits using affordable injection-molded plastic material connectors which could appreciably decrease the complete website link cost.

But POF has its individual problems. probably the most essential obstacle is plastic material fiber’s significant signal burning (attenuation). PMMA is becoming utilized since the lumination guiding middle for commercially supplied step-index POF and PMMA’s attenuation is about 100 dB/km. This significant attenuation appreciably limits POF’s apps in information relationship apps of the whole whole lot much more than 100m.

Here could be the exceptional information though. Developers have found that PF amorphous polymer dependent gradient-index plastic material optical fibers eradicate the attenuation concern with PMMA dependent plastic material fiber. They have made PF-polymer dependent Gradient-Index (GI) POF with attenuation level of only 10 dB/km. dependent on theoretical calculation, PF-polymer dependent GI POF can achieve comparable level of attenuation as silica-based goblet fibers of 0.3dB/km.

With a optimized refractive-index profile while in the PF-polymer dependent GI POF, a whole whole lot much more than 10Gb/s information transmission pace could be achieved much more than 1km. This could be the metrics of PF-polymer’s reduced intrinsic burning and reduced substance dispersion.

Combined with this theoretically feasible significant bandwidth and reduced complete website link cost, PF-Polymer dependent gradient-index plastic material optical fibers consists of a massive potential in fibers optic information relationship applications.forefront

Optical Fiber and Copper Cable and The Differences

Nowadays, fiber optic cable has been more and more popular instead of the copper one. Fiber optic is the latest technology in cabling or wiring system that allows you to get more advantages. However, those two different types actually have several different varieties of uses either in office or residential areas. If you want to know more about the differences of those two cables, you had better read this article well.

Let us have more understanding on the basic information of copper cable first. This is the older type of cable that has been used for over a hundred years in some different systems. You will find this cable traditionally used as telephone wire, speaker system wire, as well as computer wire.

What about fiber optic one? This latest technology contains some strands of plastic or glass to transmit information. Besides, it also transmits the data in form of light instead of electricity. A little bit different from copper one, fiber optic could not transmit electricity. However, this kind of cable offers higher theoretical performance.

While the other type consists of plastic or glass strands, copper cables contain a single thread of copper. The size will be quite different based on the purpose of the cable. It could be in thin or small size, but you can also find some types that come in large size as thick as your arm. Those are sometimes protected with a covering of another type of metal. The covering is usually called braiding.

Besides, those two types of cable also have different resistance against interface. Copper cable usually is quite weak to some kinds of signal interface, such as those from cell phones or microwaves. Therefore, you should not operate or use any device that might trigger interface. However, you will not find this certain problem when you are using fiber optic cable.

There are several different benefits offered by those two different cables. You might find some risks of interface from copper cable, but it will be a great option if you are looking for cheaper product for some home requirements. Meanwhile, you will get great convenience from optical fiber since it could transmit multi-channel audio through a single line. This ability also makes this certain cable very popular for home theater system wiring. However, you need to pay more money to afford it.

Now, you have had enough information about the difference of optical fiber and copper cable. You can cow choose the most appropriate one to support your system.
