Description

The Model 8300 is a 4-channel T1/El Fiber Optic Multiplexer 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 optimum flexibility, extremely low current consumption and high reliability.

Transparent to the framing format, the LT8300's T1/El interface shapes the transmit pulse to support CCITT G.703. Line distances for connecting to DSX-1 cross connects can be from 0 to 655 feet. The internal elastic buffer removes jitter from transmit data.

Each channel offers four LED indicators to ease installation and troubleshooting--one each for Power, Alarm, T1 /E 1 Signal Loss, BPV violations and Sync Active. Individual channels provide 8 DIP switches, accessible from the panel, to control settings for line code, line length, local loopback or remote loopback.

Each channel's flashing alarm LED will indicate any invalid DIP switch setting such as when the line code does not match the line length setting. The intelligent line code setting switch will eliminate any confusion. The LT8300 is compatible with all popular types and sizes of optic cable. Fiber optic connectors are ST; FC or 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 12VDC or 115/230VAC with an external power cube.
