Fiber Optic Multiplexer 
Analog line extension

horizontal rule

4 to 24 channels of Analog or Intercom Signals over single mode or multimode fiber optic cable. It supports voice bandwidths from 300 Hz to 3.4 KHz. The analog interface is for FSK (frequency shift key) applications. It has a 600 ohm isolation audio transformer and supports voltages from 0 to 3 Vpp. The intercom interface is for 4-wire voice communication. It connects to a handset with mouth-and-ear piece.

Applications

The TC8000 is frequently used to link voice communications devices in telecommunications and SCADA environments.  It is also used in harsh environments where ground loops, EMI/RFI interference and lightning conditions may occur.

Description

The TC8000 multiplexes up to 24 channels of Analog or Intercom Signals over single mode or multimode fiber optic cable. It supports voice bandwidths from 300 Hz to 3.4 KHz. The analog interface is for FSK (frequency shift key) applications. It has a 600 ohm isolation audio transformer and supports voltages from 0 to 3 Vpp. The intercom interface is for 4-wire voice communication. It connects to a handset with mouth-and-ear piece.

The TC8000 digitizes the audio signals and converts them to PCM (pulse code modulation). Since the analog and voice signals are digitized, the voice quality does not degrade over extended distances. Distances to 30 km are typical via 1300nm single mode fiber, to 4 km over 850nm multimode fiber.

The TC8000 Fiber Optic Multiplexer is available standalone or rack mount. Standalone versions support up to 24 channels, rack mount support up to 12 channels. RJ-11 ports are provided on the rear side to connect with handsets or customer's audio devices.

Built-in power redundancy is standard on the TC8000. Optical redundancy is available as an option. Fiber Optical connectors are ST; FC is optional. Electrical connectors are RJ-11. Power is 9 to 12VDC or 115/230VAC with an external power cube.
