An SHDSL Modem is a transmission device that enables high-speed and stable data transmission over long distances using telephone lines.
In the case of methods such as UTP and optical wiring, huge costs are required when it comes to laying optical fiber cables that extend over several kilometers. SHDSL Modem, on the other hand, is relatively simple and requires only a short construction period, resulting in a low-cost, long-distance transmission network.
Because SHDSL modems can be installed at very low cost, they are very suitable for use in large areas such as factories, airports, and railroads.
SHDSL Modem is used for existing telephone lines. Since they allow LANs to be extended to locations several kilometers away, they are well suited for installation in facilities that boast extensive grounds. Examples include factory premises, parking lots, campuses, shopping malls, ski resorts, airports, and train stations.
Even if LAN wiring and optical fiber installation would be expensive, network and LAN extension can be done at low cost by using already installed telephone lines. In this way, it is an excellent cost-effective means of using existing facilities as they are.
The SHDSL system is an xDSL communication standard formulated based on the HDSL system. SHDSL uses two pairs of lines, using the same frequency bandwidth in the uplink and downlink directions.
Because of the use of telephone lines, SHDSL requires a modem to access the Internet, and SHDSL Modems are used for this purpose.
While Ethernet is limited to a maximum distance of 100m, SHDSL and VDSL can extend LANs to several kilometers. In addition, high-speed communication is also possible. Furthermore, the symmetrical nature of SHDSL and VDSL modems enables bi-directional communication at the same speed. VDSL modems can achieve bi-directional maximum speed of 100 Mbps.
SHDSL Modem has the following features:
Installation costs are far lower than other methods such as optical fiber. This is because existing premises telephone lines are used, so there is no need for any new wiring work. Compared to other methods that require wiring work and other construction costs, installation costs are lower.
Another advantage of SHDSL Modem is that installation itself is by far the easiest. Simply install SHDSL Modem on both ends of an existing telephone line. Metal lines (copper or electric wires) can also be used.
However, SHDSL requires that the metal line be an open line. Even in areas where the path from the base station to the user is partially wired with fiber optic cable, SHDSL communication is possible as long as the original copper line is still available.
SHDSL Modems can be connected point-to-point, that is, one modem to another modem, over a distance of approximately 7km with a 0.4m diameter core wire.
Other types of connections include point-to-multipoint, where multiple SHDSL Modems are connected to a single SHDSL Modem, and ring connections, where Modems are connected to each other in a ring.
SHDSL Modems can use additional bonding technology to increase speed. Bonding is a technology that bundles multiple lines together. By bundling lines together, speeds can be improved.
Bonding can also improve service continuity by providing redundancy in the event of physical failure of a network interface or failure of the network switch to which it is connected.
