TCF-142 Serial to Fiber Converter

Lead time 4-22 days
SKU
TCF-142
Extend the reach of your RS-232/422/485 serial devices to up to 5 km.
Details
The TCF-142 Series converter is equipped with a multiple interface circuit that can handle
RS-232, or RS-422/485 serial interfaces and multi-mode or single-mode fiber.

Moxa TCF-142-M converter is used to extend serial transmission distance up to 5 km (TCF-142-M
multi-mode fiber).

Main Features

* Ring or point-to-point transmission
* Convert RS-232/422/485 signal to ST Multi-mode fiber
* Extend RS-232/422/485 transmission distance - 5 km with multi mode TCF-142-M
* Compact size
* Decrease signal interference
* Protects against electronic degradation/chemical corrosion
* Support for baudrates up to 921.6 Kbps
* Extended operating temperature from -40 to 75°C

Why Convert Serial to Fiber?

Fiber communications not only extends the communication distance, but is also beneficial in
many other ways, such as:

* Immunity from electrical interference: Optical fiber is not affected by electromagnetic
interference or radio frequency interference, provides a clean communication path, and is immune
from cross-talk.

* Insulation: Optical fiber is an insulator; the glass fiber eliminates the need for using an
electric current as the data transmission medium.

* Security: Optical fiber cannot be tapped by conventional electronic means,
and is very difficult to tap into optically. Furthermore, radio and satellite communication signals can
be easily captured for decoding.

* Reliability and Maintenance: Optical fiber is immune from adverse temperature and
moisture conditions, does not corrode or lose its signal, and is not affected by short circuits, power
surges, or static electricity.
