While <a href="/wiki/Access_network" title="Access network">access networks</a> are referred to as <i><a href="/wiki/Last_mile_(telecommunications)" title="Last mile (telecommunications)">last-mile</a></i> technologies, cable Internet systems can typically operate where the distance between the modem and the termination system is up to 160 kilometres (99 mi). If the HFC network is large, the cable modem termination system can be grouped into hubs for efficient management. Several standards have been used for cable internet, but the most common is DOCSIS.<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><p>A cable modem at the customer is connected via coaxial cable to an optical node, and thus into an HFC network. An optical node serves many modems as the modems are connected with coaxial cable to a coaxial cable "trunk" via distribution "taps" on the trunk, which then connects to the node, possibly using amplifiers along the trunk. The optical node converts the Radiofrequency (RF) signal in the coaxial cable trunk into light pulses to be sent through optical fibers in the HFC network. At the other end of the network, an optics platform or headend platform converts the light pulses into RF signals in coaxial cables again using transmitter and receiver modules,<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-CCAP™_Operations_Support_System_Interface_3-0" class="reference"><a href="#cite_note-CCAP™_Operations_Support_System_Interface-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> and the cable modem termination system (CMTS) connects to these coaxial cables.
