TC3240 manual



The TC3240 is frequently used by Data Service Providers to control the bandwidth they offer to customers. It is also used for its ability to transmit over long distances (100km or farther) without connecting to additional hardware, e.g. a Switch or a Router. The Hardened Temperature option enables it to be used in extreme environments.

Featuring High Security, Long Distance capability and Rate Control, the new model TC3240 10/100M 4-port Switching/Bridging Fiber Optic Ethernet Media Converter converts or connects 10/100Base-TX (UTP) networks to 100Base-FX (Fiber Optic) networks.

The TC3240 includes a built-in switch that enables distances up to 100km without additional hardware (e.g. Switch or Router).  It can be managed through any Web Browser, SNMP, Telnet or Serial Console.  Configuration settings can be stored and ecovered to simplify network administration, and, firmware can be remotely uploaded.  VLAN and Network Time Protocol (NTP) are supported.

The TC3240 also addresses several important Security issues.  It allows up to four different IP address aliases, manageable privilege levels for users, and is password protected.  VLAN is also implemented to secure access to the TC3240. 

Rate Control, especially important to data service providers, gives users the ability to control or limit bandwidth. Data rates for Rate Control can be set in 32kbps increments, up to 100 Mbps.  A “one fiber, bi-directional” version is available for maximizing fiber optic cable usage. 

The TC3240 provides 10/100Mbps Auto-Negotiation and automatically adapts to full or half-duplex mode. Transparent to the network, it operates effectively even during high-demand traffic loads.  The “Huge Frame” feature enables handling of packets up to 1916 bytes.

An Industrial Hardened version is available for harsh environments (e.g. Process Control applications in Manufacturing, Utility, SCADA, Transportation, & Traffic Control). This version complies with most pertinent environmental and temperature specifications (-40°C to 80°C).  Standard temperature range is -10°C to 50°C. The optional high temperature version provides a range of -20°C to 70°C.

The TC3240 supports single mode distances up to 100 km (1550nm laser) and works with all types and sizes of fiber optic cable. Fiber optic connectors are ST, FC or SC. The UTP connector is RJ-45 Female.

Dry contact alarms are provided for connection to remote network management systems. A local loopback feature, eight LED indicators and an Uplink/Downlink slide switch are provided on the front panel to assist with installation and troubleshooting.

Standard power is 12VDC and includes built-in redundancy. Optional power sources include 24VDC, -48VDC, 125VDC or 115/230VAC with an with an external power cube. The TC3220S is the standalone/wall-mount unit. The TC3220R rack-mount version fits into the TCRM192 or TCRM196 19" rack-mount card cages.
