Ethernet Over Coax, EOC:

 

 

 

 

 

 

   

 

Introduction

 

The EOC-010X are point-to-multipoint EoC (Ethernet over Coax) solution that efficiently extends 10/100 Ethernet circuits to over 800 meters (2,624feet) at 160Mbps using existing coaxial cable. The EOC-010X will allow Ethernet connectivity in existing facilities or homes without pulling extra cable. This is perfect solution for Ethernet on the factory floor where systems have been upgraded from slower serial communication to Ethernet networking. The EOC-010X is used in Coaxial cable systems to extend Ethernet connectivity over existing CCTV/CATV grade Coaxial cable. The EOC-010xM is a master/bridge unit which will connect to multiple EOC-010xS subscriber units.    

  

Product Features
  • High-speed up to 160Mbps communications link over existing coaxial cable, symmetrical on EoCNA 160Mbps @up to 800 meters (2624 feet), reach down to 32Mbps @about 1.2Km (4000 feet) 
  • Operates transparently to high layer protocols such as TCP/IP
  • Auto-MDIX and auto-negotiation 10Base-T or 100Base-TX and Full or Half-Duplex on the Ethernet port
  • Plug and Play design for simple installation, single switch configuration
  • Status LEDs for simple monitoring of the device and connection status
  • Supports cascaded mode, can up to 32 units
 
Product Series

1. EOC-0101x seres : provide the simple bridge function as Coax to Ethernet. 

2. EOC-0102x series : One more Ethernet port than EOC-0101. Also provide powerful network management function, like 802.1Q, 802.1p and Port/Queue based Rate limiting.
