APPLICATIONS

The LT3220 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.

DESCRIPTION

Featuring Bandwidth Control, the Model LT3220 10/100M 2-port Switching/Bridging Fiber Optic Ethernet Media Converter converts or connects 10/100Base-TX (UTP) networks to 100Base-FX (Fiber Optic) networks.

Bandwidth Control gives users, especially data service providers, the ability to control or limit bandwidth. Data rates for Rate Control can be set at 32kbps increments, up to 100M. It can be managed through any Web Browser, Telnet or Serial Console. Password protection is provided.

The LT3220 includes a built-in switch that enables distances up to 100km without additional hardware (e.g. Switch or Router). It 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.

Standard temperature range is -10°C to 50°C. The optional high temperature version provides a range of -20°C to 70°C. A hardened temperature version is also available and provides a range of -40°C to 80°C which exceeds NEMA and CALTRANs specifications.

The LT3220 supports single mode distances up to 100 km (1550nm laser) and works with all types and sizes of fiber optic cable. A two-way "one fiber" single mode version is available. 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 LT3220S is the standalone/wallmount unit. The LT3220R rackmount version fits into 19" rackmount card cages.
