For both of them, Twoosk telecom marketplace can be you perfect ally. The differences between theory and practical implementations can be significant, so stay aware of these scenarios. To us, it was always a no-brainer that a DOCSIS network-based deployment would have favorable economics compared to a fiber-based model. Today we are looking to extend the RF range of coax cable up to 1.8 GHz (investigation for up to 3 GHz is underway for even more capacity!). Through a SW upgrade, some CMTSs can offer partial DOCSIS 3.1 support, still better than DOCSIS 3.0. CAPEX per bit of bandwidth (i.e. He also hosts a popular industry YouTube and Podcast – “Get Your Tech On“.

[1] DOCSIS 4.0 supports a downstream throughput with 4096-QAM and 25 kHz subcarrier spacing of up to 1.89 Gbps per 192 MHz OFDM channel. If you look at fiber objectively from any other perspective it outperforms DOCSIS. Should operators skip DOCSIS 3.1 and pursue FTTH? On the other hand, FTTH – Fiber To The Home, also called Fiber To The Premises (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartments and businesses to provide high-speed internet access. For example, the data speeds needed to download an HD movie are much greater than the speeds needed to load a link in a web browser.
