MOXA White Paper Expand Your Serial COMs with Optical Fiber

Page 6 of 6

• Up to 40 km transmission distance for single mode fiber

• Optical isolation available for the serial port

• RS-232-only models are available

• Each NPort IA5150 comes with redundant power inputs

• Transmission line and power failure alarms supported

• DIN-rail mounting is standard

How to Choose the Right Solution

If the optical fiber links of your application are less than 2 km,

and you can use multi mode fiber, then it is better to choose the

TCF-142 media converters since the multi mode TCF-142

models are much cheaper. On the other hand, if you are using

single mode fiber, then the NPort IA solution could be a bette

choice since each optical fiber link can stretch up to 40 km

(twice the maximum allowed optical fiber length for TCF-142).

Your choice will also be determined by technical

considerations. For example, you may want to use the

TCF-142’s easy to configure fiber ring capability. On the other

hand, the NPort IA5150’s ability to send alarms when a failure

occurs, as well as the serial port isolation feature, could be

determining factors.
