MJT
Surge Protectors
The MTJ Series of surge protectors, ideal for RJ11 and
RJ45-style twisted pair interfaces, will ensure the
reliable operation of Local and Wide Area Networks,
offering protection for LAN interface technologies such
as Ethernet 10BASE T, 100BASE T, CDDI, 100VG-AnyLan and
ATM155. For WAN and Telco applications protection is
offered for environments including ISDN, T1, FT1, DDS,
analog dial up modems, faxes and more.
Features
»
State-of-the-art, avalanche diode and thyristor
technology
»
Compact, in-line installation
»
High speed, high energy handling capability
»
Low shunt capacitance to reduce signal loss
The MTJ Series devices guard sensitive data networks
against lightning induced surges, AC power interference,
electrostatic discharge, and ground loop energies.
Typical applications include NICs, switches, hubs,
repeaters, bridges, routers, point of sale terminals,
modems, fax machines, telephones and most other types of
communications equipment utilizing RJ45 or RJ11 modular
telephone jacks.
High speed avalanche diode technology is used in
conjunction with low capacitance circuitry enabling the
protectors to function at a much greater bandwidth
without causing signal degradation.
Standard units are available with up to 8 wires
protected on the RJ45 devices, and up to 6 wires
protected on the RJ11 device. All this, in combination
with their small size, makes the MTJ exceedingly
versatile.
