Everything is being changed by video. Communications and videography companies all over the world such as pulse8 media are searching for ways to diversify their revenue streams and to increase their ROI. At the same time, they are faced with the expenses to upgrade their existing networks. Getting customers connected isn’t so much the problem, it is providing a high level of service that consumers expect these days in our well-connected society.
Although there is a lot of talk about bandwidth and high-speed, most people are not aware that most households are still using the telephone company’s old copper telephone wire for their internet services.
Implementing vectoring can greatly improve performance, whether as a stand-alone modification or in combination with bonded pairs. Using fibre as the backbone – and using existing copper pairs on last-mile connections – that is a good example of a vectored, hybrid network.
Hybrid Network Realities
Broadband multimedia services are very popular. For telecommunication service providers, this is a double-edged sword. Fierce competition coming from cable operators, rising consumer expectations, and declines in voice traffic revenues have made service bundles, especially those including high-definition TV, essential to survival.
For pair-bonding, the standard approach that is taken is transmitting Ethernet packets using a high-speed link on a line through any physical transport layer. That includes any DSL version, including the latest VDSL technology The transmission mode works by layer or stacking bonding fragments with one byte in overhead to each 64 bytes of data that is transmitted. A frame check sequence is used to detect and reduce any errors.
Although it is suggested by conventional wisdom that high-level performance is only delivered by FTTH (fibre-to-the-home) network architecture, another option is available. VDSL is less expensive than traditional systems, and a next-generation form of DSL technology. Service provides can use Ethernet pair bonding to use hybrid network systems that provide significant advantages compared to using just one wire. Improvements and advances in technology, stability, reach and overall capacity within the copper legal infrastructure are all key to deploying services using a twisted-pair network.
As VDSL technology continues to improve, it further enables advanced multimedia services to use high performance vectored services. With stronger bonded copper pairs and reduced costs, both rural areas and those near the Central Office are both enjoying the same high-speed access bandwidth level of service.
The Legacy Of Valuable Assets
When the end-user has access to a second wire, pair-bonded VDSL is a highly viable solution. Extended rates and reach results in reduced costs because fewer cabinets are needed. The lowered costs and advanced capabilities of hybrid systems make it possible for communications companies to make upgrades to their networks, no matter what economic market disadvantages they may currently have.
Telco copper advanced broadband services offer easy and quick deployed. However, it is limited by distance. Suburban and urban areas are the locations that are most easily identifiable for FTTh network architecture. With businesses and homes getting spread into rural areas and further apart, this technology’s effects are becoming more stretched. Providers are limited by distance, so they must consider crosstalk in the cable, termination points, and the quality of their wire.
In fact, the combination of crosstalk in signals from adjacent wire pairs and signal loss on account of the distance of a twisted pair cable, work to limit high-speed VDSL technology from being deployed. For specific service quality objectives, deployment is limited by service providers. Generally speaking, the combination of crosstalk that is introduced by signals from the adjacent wire pairs and signal loss from twisted pair cable limit the range that high-speed VDSL services can be deployed.
Current innovations in technology are making VDSL the top choice in technology for communications companies that offer multimedia services. Extended reach and increased improvements are overcoming some performance-inhibiting obstacles that traditional copper legal infrastructure face.
