ATC-277MM Multi-mode Fiber to serial Converter
The ATC-277MM is a Fiber Modem, that allow the connection of RS232/422/485 devices over a multi-mode fiber cable.
The device allows connection up to 2Km of fiber cable and supports point to point or ring (point to multipoint) networking.
The converter can also be used as "Repeater" to create a multi-drop master/slave configuration, allowing one serial device to talk to multiple slave devices around a fiber ring.

ATC-277SM Single-mode Fiber to serial Converter
The ATC-277SM is a Single Mode Optical Fiber Modem, that allow the connection of RS232/422/485 devices over a single-mode fiber cable.
The device allows connection over up to 20Km of fiber cable and supports point to point or ring (point to multipoint) networking.
The converter can also be used as "Repeater" to create a multi-drop master/slave configuration, allowing one serial device to talk to multiple slave devices around a fiber ring.

TRP-C39 Multimode Fiber to serial converter
This device allows to connect devices provided of RS232/422/485 interface, using multimode fiber optic and insuring, in this way, the transferred data integrity in noise environments. It is suitable to solve ground loops problems.

TRP-C39S Single-mode Fiber to serial converter
This device allows to connect apparatus equipped with a RS232/422/485 interface, using a single mode fiber optic cable. It is particularly suited were there is the need to transmit data over long distance (up to 40Km).
