The EoC access technology is never out!

What is the EoC access technology?

  “Ethernet over Coax (EoC) is a family of technologies that supports the transmission of Ethernet frames over coaxial cable.”

  “Ethernet over copper (also known as EoC) is a form of Ethernet in the first mile connection that uses twisted pair copper telephone wire. It uses the same 8P8C modular connector used by conventional Ethernet over twisted pair. The physical layers used for Ethernet over copper are 2BASE-TL and 10PASS-TS.“

Yes, EoC technology came from the traditional cable network.

  EoC technology is a technology for implementing Ethernet data transmission over coaxial cable. Since the current cable television signal is transmitted within the frequency band of 111 to 860 MHz, EoC technology uses other frequency bands for transmission to enable it to be on a coaxial cable. At the same time, cable TV signals and data signals are transmitted. In the transmission process, the cable TV signal and data signal are first sent to the user through the combiner and the cable television network. At the subscriber end, the television signal and the data signal are separated by a splitter and the corresponding subscriber terminal equipment is accessed.

How many types of the EoC technology?

  EoC access technologies include baseband EoC technology, MoCA, HomePlug (AV) over Coax, WiFi over Cable, and HomePNA over Cable. Among them, baseband EoC technology is a technology that directly transmits Ethernet signals over a coaxial cable, and MoCA technology is originally used. Designed for home connectivity based on coaxial cable, HomePNA is a power line based data transmission technology. With or without modification, these technologies can directly implement data transmission over coaxial cable and provide broadband access.
According to whether the Ethernet signal is modulated, EoC technology can be divided into baseband EoC technology and modulated EoC technology, and these two technologies can also be called passive EoC and active EoC technology. Modulation EoC (active EoC) technologies include MoCA, HomePlug (AV) over Coax, WiFi over Cable, and HomePNA over Cable.
  According to the different working frequency band of EoC technology, it can be divided into low-frequency EoC and high-frequency EoC technology. Low-frequency EoC technologies include baseband EoC technology, HomePlug (AV) over Coax, and HomePNA over Cable; high-frequency EoC technologies include MoCA and WiFi over Cable technologies.

Where will EoC solution be used in today’s telecom projects?

  The EoC technology is generally combined with the PON technology. The PON technology is responsible for the access network part. The EoC technology completes the last 100m access for the user. When using PON+EoC networking, the network structure is as shown in the figure:

  In PON+EoC networking, PON network construction can be FTTB or FTTC. In the case of FTTB mode, the network structure of “fiber-to-the-building, direct users of optical network, PON transmission, coaxial cable access, EoC access” is adopted. The HFC network transmission system does not change. The bi-directional network optical link adopts the PON transmission technology, and the network below the building/floor adopts the EoC transmission technology that transmits the Ethernet signal based on the coaxial cable. If it is FTTC mode, the network structure of “fiber to cell, first-order power amplifier, PON transmission, coaxial cable entry, EoC access” is adopted. Different from the FTTB mode, since the optical node location of the HFC network is also relatively high, it may require a first-stage amplification.
