TC8116 Multi-Interface Fiber Multiplexer - Fiber Optic Modems, Multiplexers, Multidrop (SCADA) Modem, RS-232, RS-422, RS-485,V.35, T1/E1, T3/E3, Intercom/V

The TC8116 Fiber Optic Multiplexer provides a flexible, inexpensive method for connecting async/sync terminals, printers, and status collecting devices. It is often used in harsh environments where EMI/RFI interference, ground loops and lightning conditions may exist. The TC8116 can also be used to extend telephone lines to remote locations with the Model TC1900 RS-232 or Fiber Telephone Extenders.

The TC8116 is an 8 or 16-channel fiber optic multiplexer with interchangeable interfaces and built-in power redundancy. Optical redundancy is optional. It supports data rates up to 56Kbps*. The TC8116 is available in four configurations:

Standard interfaces include RS-232, RS-422, RS-485 (2 or 4 wire), TTL & Dry Contact Closure. Synchronous versions must be RS-232. Electrical interfaces are modular and interchangeable in 4-channel increments at any time--before or after installation. Because different interfaces can be mixed in 4-Channel increments, a wide variety of interface combinations are available. Here are some sample configurations:

TC8116		INTERFACE TYPE
TC8116		Async RS-232 Channels	Async RS-422 / RS-485 Channels	Dry Contact Detector	Dry Contact Closure	Intercom (Voice & Buzz)
C O N F I G U R A T I O N	A	4	4	4	4	0
	B	4	8	0	0	1
	C	8	4	0	0	1
	D	8	8	0	0	0
	E	16	0	0	0	0
	F	0	12	0	0	1
	G	12	0	0	0	1

Diagnostics are extensive and include DIP switches for Local & Remote Loopback, a Test Signal Generator, an Electrical Signal Polarity Inverter, and other application configuration switches. Each unit also provides multiple LEDs for Alarm, Power, Vcc, Optic Signal Status, and Tx & Rx LEDs for each channel. The built-in test signal generator verifies both device and fiber optic link operation. This feature benefits users by helping technicians verify that both local & remote devices and the fiber optic link are operating normally. No other test equipment is required for link and device verification.

The TC8116 is compatible with all types and sizes of multimode (850/1300nm) or single mode (1300/1550nm) fiber optic cable. Fiber optic connectors are ST or FC. Electrical connectors are RJ-11. Power is 12VDC (standard) or 24VDC, -48VDC, or 115/230VAC with an external power cube. An extreme temperature version (-20° to 70°C), Model TC8116T, is also available.
