Overview
The TC EXTENDER transparently extends Ethernet data transmission up to 20 km across single twisted pair ( CAT5/6/7 ), coax or any existing copper wiring previously used in alarm circuits, E1/T1 circuits, RS-232, RS-422, RS-485, CCTV and CATV applications.
Long Distance Ethernet Transmission over Copper
SHDSL is the technology of choice for the transmission of digital data over long distance copper wires of a network. Although performance depends on the characteristics of the cable used, the reach of SHDSL is much further than any other DSL technology currently available. In addition, upload and download bandwidth is symmetrical boasting data rates as high as 15.3 Mbps over 2-wire copper and 30 Mbps over 4-wire copper.
The TC EXTENDER is protocol transparent. With two SHDSL ports you can easily set up point-to-point, linear or ring network structures with ranges of up to 20 km. These simple and effective Ethernet Extenders are perfect for industrial environments, commercial buildings, residential units, hospitality environments, connecting a remote office or private-network backbone to a corporate LAN … anywhere you need Ethernet communication links between separated LANs or LAN devices (i.e. PCs, digital sensors, VoIP phones, WiFi APs, IP cameras and more).
Two software configurable digital outputs are available for external device alarm generation.
For “plug and play” long distance Ethernet data transmission, the TC EXTENDER 2001 ETH-2S is the ideal solution.

Application Diagrams
| Point-to-point connection |
|---|
There can be a maximum distance of 20 km between two devices. The Ethernet extender automatically recognizes if the path is constructed on a 2-wire or 4-wire path. If the devices have detected a 4-wire line, the transmission rate is automatically increased (usually doubled) depending on the line quality. If one of the connections fails, the data is transmitted via the remaining conductors at single transmission speed. In this way, a reliable redundancy operation is supported.

| Line structure |
There can be a maximum distance of 20 km between two devices.
  |
| Star structure |
Since each device features two SHDSL ports, you need only three devices.
 |
| Redundant ring structure |
| The overall availability of the system is significantly increased by a redundant ring. There can be a maximum distance of 20 km between two devices. You can integrate up to 50 devices in a ring. If there is a ring interruption, Ethernet communication is possible again after the following response time: tRecovery = 600 ms + number of devices x 100 ms. The paths of the SHDSL ring should show a very high connection quality during normal operation. If that is not the case, the reaction time can deviate from the value calculated above.  |
| Redundant data communication in rotating applications |
The Ethernet extenders are connected via a 4-wire line. The connection is therefore redundantly established. Using the two digital outputs on the Ethernet extender, you can monitor the slip ring communication.
 |
| Range |
| The maximum possible SHDSL data rate depends on several parameters. Two important parameters are the cable length and cable cross section. This diagram illustrates the dependency of the maximum SHDSL data rate on the line length with 3 cable types. Longer distances can be achieved using high-quality cables with larger diameters. The TC EXTENDER enables data rates over 2-wire copper from 32 kbps to 15.3 Mbps. Data rates of up to 30 Mbps are possible over 4-wire copper.
