Flexible solutions are required such as the DBx range of nodes and network amplifiers with pluggable or switchable diplexers and amplifier modules. Alternatively, the direction neutral amplifier (DNA), diplex filter free 1.8 GHz amplifier is perfect in this scenario.<\/p>\n\n\n\n<h2 class=\"gb-headline gb-headline-4b572e45 gb-headline-text gb-headline-h2-in-content\">Potential issues?<\/h2>\n\n\n\n<p class=\"gb-headline gb-headline-c9b08205 gb-headline-text\">DOCSIS 4.0 ESD is a robust protocol, but high quality components are crucial. Adjacent Device Interference could be a problem where ESD co-exists with a legacy platform. Some legacy outdoor taps and line passives incorporate bypass switches in the backbox, which can cause problems when new 1800 MHz faceplates are mounted, as some of the switches experience severe resonance in the 1300-1600 MHz range.<\/p>\n\n<\/div>\n\n<div class=\"gb-container gb-container-172b366a gb-container-con-buttons-bottom\">\n\n<h2 class=\"gb-headline gb-headline-7ce6fa4b gb-headline-text gb-headline-head-bottom-buttons\">Useful Links<\/h2>\n\n\n<div class=\"gb-button-wrapper gb-button-wrapper-5300c273 gb-button-wrapper-after-con-buttons\">\n\n<a class=\"gb-button gb-button-5e4e6530 gb-button-text gb-button-bottom-button\" href=\"https:\/\/emea.technetix.com\/hfc-networks\/multitaps-and-line-passives\/xgt-taps\/\">XGT taps<\/a>\n\n\n\n<a class=\"gb-button gb-button-3eadfa91 gb-button-text gb-button-bottom-button\" href=\"https:\/\/emea.technetix.com\/hfc-networks\/access-amplifiers\/direction-neutral-amplifier\/\">DNA-1800<\/a>\n\n\n\n<a class=\"gb-button gb-button-4ceed201 gb-button-text gb-button-bottom-button\" href=\"https:\/\/emea.technetix.com\/hfc-networks\/access-amplifiers\/dbx-smart-rf-amplifiers\/\">DBx smart RF amplifiers<\/a>\n\n\n\n<a class=\"gb-button gb-button-903f7f13 gb-button-text gb-button-bottom-button\" href=\"https:\/\/emea.technetix.com\/products\/broadband-technology\/signal-conditioning\/\">1.8 GHz signal conditioning<\/a>\n\n\n\n<a class=\"gb-button gb-button-74bfad52 gb-button-text gb-button-bottom-button\" href=\"https:\/\/emea.technetix.com\/contact-us\">Contact us<\/a>\n\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Extended Spectrum DOCSIS Upgrade your network to Extended Spectrum (ESD) DOCSIS 4.0 ESD utilises more spectrum in the network: ESD supports a more robust modulation scheme known as Orthogonal Frequency Division Multiplexing (OFDM), advanced forward error correction and advanced queue management.
