Hybrid fiber, coaxial, and copper designs supply an `out-of-the-container` approach

by using Donald T. GALL and MITCH SHAPIRO

alternatives abound for operators who choose from latest off-the-shelf electronics as necessary to customise a network design.

What in case you have a "greenfield" probability to offer switched telephony or "undeniable ancient tv carrier" to create incremental revenues without sacrificing your core company? Your current cable plant is in notably first rate situation and supplying first-class video to your subscribers, but you simply don`t consider a hybrid fiber/coaxial (HFC) phone system will offer the reliability you require. additionally, different things being equal, in case you present telephony you might want to keep on with proven expertise with as little possibility as feasible.

today`s state-of-the-paintings telecommunications methods (each cell business and cable tv) have been vastly enhanced with the introduction of transport fiber optics. despite the fact, there are nonetheless big roadblocks to constructing a single cost-effective communications network that does every little thing neatly. Twisted-pair networks battle with bandwidth and switching needs, whereas coaxial networks battle with reliability and powering issues. each networks in my view have supplied purposeful solutions in their respective core corporations, but there are technical and monetary hurdles to conquer to create a truly integrated solution that delivers voice, statistics, and video. while it`s beautiful to be on the innovative of expertise, it`s constantly top-quality to be just in the back of the blade!

below the correct circumstances, a community that makes use of both twisted-pair and coaxial applied sciences as an built-in device combines the better of both worlds and might be simply the ticket. This alternative architecture gives twisted-pair distribution with a distinct perspective via holding the number of copper pairs small to reduce weight on the overlashed coaxial plant and cut back building and splicing labor. whereas this method is extra in your price range than common full copper telephony strategies, its business mannequin simplest works if a big percentage of the switched telephony enterprise can also be captured. The coaxial component will also be a customary HFC layout--an evolutionary, not innovative, approach to convergence, diversifications of which had been effectively deployed in the united kingdom, and ingredients of Europe.

A hybrid fiber/ coaxial/copper (HFCC) architecture makes use of current off-the-shelf items to construct a totally reliable and low cost community that overcomes the inherent problems of established single network approaches. it is in a position to delivering all existing applications akin to analog and digital video, high-pace analog and digital subscriber loop (DSL) records services as well as future purposes like demand facet management (DSM) and video on demand (VOD).

A key to deploying an HFCC-like structure is to avoid designing a community from the "monopoly" standpoint. with out the improvement of a hundred% penetration or a guaranteed cost of return on capital, a success community operators should find the way to install technology incrementally to healthy their business plans. It is that this potential to installation electronics most effective as mandatory that makes the HFCC model a manageable approach.

The transport element of the combined HFCC plant is fiber optics, which provides the crucial bandwidth and low losses to enable the deployment of functions throughout massive areas. The exact network design will rely on the particular person corporations` marketing strategy and the measurement of the serving areas. at the node serving area, fiber is terminated into both a coaxial bus and a twisted-pair network.

What makes this method enjoyable is the methodology during which the coaxial and twisted-pair plant life are mixed into a seamless beginning platform for narrowband and broadband features.

The HFCC community topology includes a normal HFC network that serves node sizes ranging from four hundred to 750 buildings with a twisted-pair copper overlay community serving the same number of homes or extra. The copper might also prolong past cable-television node boundaries to make efficient use of the telephony electronics. The change between this topology and a traditional telephony overlay community as constructed within the uk is the variety of copper pairs deployed. within the HFCC design, the copper cable measurement is limited to 50 or seventy five pairs emanating from any node in any route. The small size of the copper bundles permits overlashing without worry of overloading the present strand.

within the HFCC network, telephony nodes are deployed using a typical Synchronous Optical network interface on the OC-1 (fifty one-Mbit/sec) price both in a folded or universal ring architecture. Single-fiber, 51-Mbit/sec interfaces can also be used if redundancy isn't preferred. every host digital terminal (HDT) would at the start be configured to give up to 28 DS-1 features capable of 672 nonconcentrated simple ancient cellphone service lines. As new nodes come on line, additional HDTs can be brought in blocks of 28 non-centred DS-1s. As an choice, allowing attention of lower than 2:1 can double the variety of DS-1s accessible through utility.

community design is achieved by way of breaking down the carrier enviornment into 24 domestic pockets which are expertise locations for smaller far flung digital terminals a great deal like the ordinary fiber-in-the-loop designs of the cell business. at the beginning, as much as 48 subscribers may be served directly from the node using the long-established 50-pair cables and a minimally configured remote terminal. As penetration increases enormously in any component of the serving area, remote terminals should be positioned at those predetermined places. This technique makes it possible for the re-use of all but two pairs of the 50-pair cable feeding that pocket with a T1 circuit. If the serving enviornment has gigantic numbers of assorted dwelling instruments, remote terminals will also be placed at the time of building to deliver shared tenant features for the whole complex or constructing.

The HFCC design, depending on density, is typically capable of supply 10% to 15% penetration of each and every leg leaving the node earlier than far flung terminals are required. The far off terminals can also be powered in the neighborhood from the cable plant`s 60V AC, or with 120V AC; in either case, every unit has eight hours of battery backup, which satisfies the need to keep the equal energy necessities as a native-change provider (LEC).

essentially the most attractive aspect of this strategy is that the operator controls each the coaxial plant and copper plant, which provides the flexibility to use the mixed community to its fullest skills. for instance, considering that the operator controls the copper, he can take excessive-speed information off the community before it is routed through a swap, thereby presenting a connectionless route for statistics that isn't field to the complications of swap loading. cell return cable modems will also be offered at a tons decrease price as a result of site visitors that prior to now passed during the LEC`s community can now be terminated at once on the operator`s headend.

for the reason that the copper plant is all new with short loops between the node and customer (constantly lower than 5000 toes), it's able to provide basically any telephony or facts carrier that LEC rivals have to offer together with asymmetric DSL and excessive-velocity DSL. Off-the-shelf plug-in cards enable an operator to give "customized, at ease information services" when purchasers need them, as a substitute of the three or 4 weeks or besides the fact that children long it takes to locate and fix the incumbent cellphone enterprise`s present forty-year-ancient plant.

From a business point of view, the HFCC network may also be a magnificent device. since it is structured as an "overlay" network, it will also be divided into two bodily separated vegetation for joint-mission applications. for example, an operator may also wish to form a joint venture with a company to deliver plain ancient phone provider or facts features to agencies and residential subscribers. With this network, the operator has the capacity to constitution the joint venture to encompass most effective the copper plant, which might now not have an effect on its core enterprise cable-tv plant. This option offers flexibility in establishing purposes that enrich the bottom line. alternative telephony suppliers be aware and like ordinary mobilephone copper applied sciences on account of their confirmed reliability. q

This basic HFCC design shows digital places for extra cellphone penetration.
