Fa referència a totes les tecnologies d'accés que utilitzen <a href="/wiki/Fibra_%C3%B2ptica" title="Fibra òptica">fibra òptica</a>. El tipus de servei FTTx es determine indicant fins a on arribe la fibra óptica que surt de la <a href="/w/index.php?title=Central_de_telecomunicacions&action=edit&redlink=1" class="new" title="Central de telecomunicacions (encara no existeix)">central de telecomunicacions</a>. L'últim tram encara sovint sol ser un parell de cables de coure. La 'x' és una variable que pot ser: </p><ul><li>'h' (<i>home</i> - llar)</li> <li>'c' (<i>curb</i> - cantonada)</li> <li>'b' (<i>building</i> - edifici)</li> <li>'f' (<i>feeder</i> - alimentador)</li> <li>'p' (<i>premises</i> - edifici)</li></ul> <p>La fibra òptica arriba fins a una gran varietat de llocs i que, en l'actualitat, es troben en un dels seus millors moments degut a la seva demanda en augment gràcies al fet que ofereix serveis de telefonia, televisió i Internet <i>(<a href="/wiki/Triple-play" title="Triple-play">Triple-play</a>)</i> amb tots els avantatges de la fibra òptica. </p><p>Les xarxes FTTx poden utilitzar dos tipus d'arquitectures. El <a href="/wiki/Punt_a_punt" class="mw-redirect" title="Punt a punt">punt a punt</a> que connecta cada usuari amb el node central o una <a href="/wiki/PON" title="PON">Xarxa òptica passiva (PON)</a> amb un divisor òptic que fa d'intermediari entre els usuaris i el node central per minimitzar la tirada de fibra. Les xarxes segueixen sent costosos, tot i que els components òptics cada cop s'abarateixen més. Encara no se sap si l'increment d'amplada de banda estimularà noves aplicacions o si seran les noves aplicacions que impulsaran l'amplada de banda. </p> <dl><dt>FTTH - Fiber to the home - Fibra fins a la llar</dt></dl> <p>Es defineix com un circuit de línia de <a href="/wiki/Banda_ampla" title="Banda ampla">banda ampla</a> a casa de l'abonat. És la més avançada de totes les xarxes i, típicament utilitza fibra monomode per connectar directament l'usuari amb el node central. A més, suporta transmissió bidireccional de veu d'alta velocitat. Es pot dir que és l'arquitectura més adient, d'entre totes, per la transmissió de dades d'alta velocitat (<a href="/wiki/Banda_ampla" title="Banda ampla">banda ampla</a>) a les llars per la seva disposició física; en concret, perquè la tirada de fibra òptica és completa i no s'utilitza en cap punt cable de coure. </p> <dl><dt>FTTB - Fiber to the building - Fibra fins a l'edifici</dt></dl> <p>En aquesta arquitectura es col·loca una unitat ONU (Optical Network Unit), que és la que comunica l'usuari amb la xarxa i realitza les funcions de filtratge i enviament de dades provinents de l'usuari, a cada habitatge d'un bloc de pisos. Aquest tipus d'arquitectura combina <a href="/wiki/Fibra_%C3%B2ptica" title="Fibra òptica">fibra òptica</a> i cable de coure. </p> <dl><dt>FTTC - Fiber to the Curb - Fibra fins a la cantonada</dt></dl> <p>En aquest cas la unitat ONU està situada en un lloc específic, de tal manera que pugui donar cobertura a un conjunt d'usuaris determinat situats en edificis diferents; mitjançant cable de coure, però. </p> <dl><dt>FTTF - Fiber to the feeder - Fibra fins a l'alimentador</dt></dl> <p>En aquest cas s'utilitza <a href="/wiki/Fibra_%C3%B2ptica" title="Fibra òptica">fibra òptica</a> en tot el tram que va des del node central fins al terminal i la resta simplement amb cable de coure. Dins de les FTTF es troba inscrita l'arquitectura HFC que també combina cable coaxial i <a href="/wiki/Fibra_%C3%B2ptica" title="Fibra òptica">fibra òptica</a>. Les HFC funcionen de tal manera que el senyal de radiodifusió s'envia a un mòdul (anomenat <i>headend</i>) que s'encarrega de convertir-lo a senyal òptic. Aquesta finalment arriba a uns hubs que realitzen la conversió inversa i el senyal es transmet des dels hubs als usuaris. </p> <dl><dt>FTTP - Fiber to the premises - Fibra fins l'edifici</dt></dl> <p>És una denominació que tant pot indicar una FTTH com una FTTB, s'aplique a edificis que tenen pisos i locals comercials amb xarxa telemàtica pròpia. </p> <dl><dt>FFTF - Fiber to the farm - Fibra cap a les granges<b> </b></dt></dl> <p>En aquest cas són els mateixos interessats des de l'entorn rural que s'espavilen per construir trams de xarxa amb fibra òptica per arribar fins a llocs on existeixen trams de fibra òptica, el perquè d'aquest model de desplegament està inspirat en la xarxa oberta guifi.net que promou que l'interessat pugui millorar el seu accés a les telecomunicacions tot i ser a zones que no són rendibles per les operadores tradicionals.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Referències"><span id="Refer.C3.A8ncies"></span>Referències</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=FTTx&action=edit&section=1" title="Modifica la secció: Referències"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="reflist {{#if: | references-column-count references-column-count-{{{col}}}" style="list-style-type: decimal;"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><span class="citation" style="font-style:normal">«<a rel="nofollow" class="external text" href="http://guifi.net/node/23504">La primera experiència d'estendre FFTF, i algunes fotografies</a>», 08-08-2009.</span></span> </li> </ol></div></div> <style data-mw-deduplicate="TemplateStyles:r33663753">.mw-parser-output .side-box{margin:4px 0;box-sizing:border-box;border:1px solid #aaa;font-size:88%;line-height:1.25em;background-color:#f9f9f9;display:flow-root}.mw-parser-output .side-box-abovebelow,.mw-parser-output .side-box-text{padding:0.25em 0.9em}.mw-parser-output .side-box-image{padding:2px 0 2px 0.9em;text-align:center}.mw-parser-output .side-box-imageright{padding:2px 0.9em 2px 0;text-align:center}@media(min-width:500px){.mw-parser-output .side-box-flex{display:flex;align-items:center}.mw-parser-output .side-box-text{flex:1;min-width:0}}@media(min-width:720px){.mw-parser-output .side-box{width:238px}.mw-parser-output .side-box-right{clear:right;float:right;margin-left:1em}.mw-parser-output .side-box-left{margin-right:1em}.mw-parser-output .side-box-center{clear:both;margin:auto}}</style><div class="side-box metadata side-box-right plainlinks"> <div class="side-box-flex"> <div class="side-box-image"><span typeof="mw:File"><span><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/Commons-logo.svg/30px-Commons-logo.svg.png" decoding="async" width="30" height="40" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/Commons-logo.svg/45px-Commons-logo.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/4a/Commons-logo.svg/59px-Commons-logo.svg.png 2x" data-file-width="1024" data-file-height="1376" /></span></span></div> <div class="side-box-text plainlist">A <span class="plainlinks"><a class="external text" href="https://commons.wikimedia.org/wiki/P%C3%A0gina_principal?uselang=ca">Wikimedia Commons</a></span> hi ha contingut multimèdia relatiu a: <i><b><a href="https://commons.wikimedia.org/wiki/Category:Fiber_to_the_x" class="extiw" title="commons:Category:Fiber to the x">FTTx</a></b></i></div></div> </div>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none;
