The TM8 fiber optic multiplexer is designed to transmit up to 8 T1 (DSX-1) or 8 E1 (G.703) circuits via optical fiber. With an embedded micro-controller, each channel of the TM8 can easily be configured and monitored through the Network Management Software (NMS). Configuration control includes LBO Settings, Line Code Selection, and AIS Enabling.

The TM8 ’s front panel provides LED status indicators, including local and remote alarms, audio disable push button controls, and NMS ports. The rear panel provides AC and DC power inputs, E1/T1 channel connections, and relay contacts.

The management port provides complete system function access with a graphical user interface menu for channel configuration, test, alarm reporting, and status display. System performance monitoring including code violation per each individual data channel, and the system optical composite signal. In addition, the TM8 ‘s internal memory provides and updates historical data performance for every 15 minutes, 24 hours and 7 days intervals.

Specific application optics provide the flexibility to meet any system requirements. These optics support multimode and singlemode fiber, and all major connector types. Transmission distances up to 10 Km via multimode and up to 50 Km via singlemode are possible. The TM8 may be configured with single or dual optics. The dual optic version provides automatic switch over in the event that a fault on the primary optical path is detected.

The TM8 is ideal for implementing simple trunking systems for premise, metropolitan, and industrial environments. Applications for the TM8 include PCS trunking, SCADA, ITS, railway networks, electrical utility networks, and cellular networks.
