T3/E3 Fiber Optic Modem

Lascomm580 T3/E3 Fiber Optic Modem provides a point to point high speed data link between two DS-3 conforming devices. The distance between adapters can be extended up to 30 km with a laser transmitter option. The T3/E3 LT3580 adapter is especially valuable for extending DS-3 circuits to another building on the premises.

Besides distance, a fiber optic link offers more advantages than coax for DS-3 data. A fiber cable has the characteristics of high bandwidth, low loss, less signal distortion, and high noise immunity. It can provide users with a clean, secure link and helps eliminate problems associated with coax cable such as noise, crosstalk, and power surges. The LT3580 also is a repeater for DS-3 data. Signals received from both fiber and coax port inputs are re-timed and reconstructed to reduce jitter and distortion.

Features:

• Compliant with ANSI T1.102-1987, TR-TSY-000499, and CCITT G.703
• Coax input port receive equalizer
• Selectable transmit line buildout (LBO) to accommodate shorter line lengths
• Low jitter with receive signals retiming at both fiber and coax port
• Offers laser transmitter an option for fiber optic interface
• Built-in self and link tests for diagnostic LED indicators on the front panel

Applications:

• Replaces coaxial cables with fiber optic link
• Extends T3-3 distance up to 30 km
• High interference environments
