100 Base-T Ethernet Media Converter


The DZC-NMC-3200 Converter complies with IEEE802.3, IEEE802.3u, IEEE802.3x Standards.

It is designed to convert a signal between 100 Base-Tx and 100 Base-Fx fast Ethernet. The data signal converted by such high performance media converter can be transmitted up to a maximum of 120Km by fiber-optic cable.

The Converter is equipped with two fiber optic

connectors (One for transmitting-Tx and another for receiving-Rx), two RJ-45 Jacks and one external power supply jack. Six LED indicators are

built-in for easy diagnostics, Ethernet Link, Ethernet Activity, Fiber Link, Fiber Activity, Full duplex and data rates. It can be configured automatically for Full Duplex or Half Duplex operation.

It is a compact, cost-effective, highly reliable

and stable device
