Lascommel 3520 is a T1/E1 Fiber Optic modem that offers advanced features such as jitter removal and a replaceable line interface module. Because it is based on modern FPGA (field programmable gate array) technology, it offers extremely low current consumptions and higher reliability. Transparent to the framing format, the LT3520's T1/E1 interface shapes the transmit pulse to support CCITT G.703, or for connecting to DSX-1 cross connects for line distances from 0 ft.-655 ft. The internal elastic buffer removes jitter from transmit data.

The LT3520 has five LED indicators to ease installation and trouble shooting, one each for power, alarm, T1/El signal loss, BPV violations, and sync active. It provides 8 DIP switches, accessible from the panel, to control settings for line code, line length, local loopback, or remote loopback setting for when the line code does not match the line length setting. The intelligent line code setting switch will eliminate any confusion.

The LT3520 is compatible will popular types and sizes optic cable. Fiber optic connectors are ST; FC and SMA are optional. Special four-position and two position feed-thru detachable terminals are provided for connecting the T1/El twisted pairs. Input power is 12VDCor 115/230VAC with an external power cube.
