![]() ![]() This might still be true at the component level, but not when you consider total installed costs. Youd have to bend it back onto itself before youd have problems. Myth #2≿iberoptic Networks Are More Expensive Than Copper ![]() Ive tied fiber into loose knots without it breaking or causing problems.įiber cable is pretty strong, agrees Kevin Burak, a networking consultant at Invensys Process Systems. With fiber, you dont have the impedance losses and pair-to-pair crosstalk problems you can have with copper when non-bonded, twisted-wire pairs separate due to improper handling. Ive seen someone pulling reinforced fiber cable through a conduit with a backhoe without any problems, says Sven Burkard, marketing manager at Hirschmann Americas. The fact that there have been no failures in the fiberoptic systems is proof of the reliability.įiber has gotten incredibly rugged, according to one of its suppliers. These can be difficult to diagnose and resolve. Due to large EMI loads in the facilities, communications errors occurred from time to time when copper media was used. The fiber cable delivered everything that was expected. ![]() The top reasons for choosing fiberoptic cable for use in the three Evansville Water and Sewer Utility (EWSU) treatments plants were bandwidth, EFI/EMI immunity and reliability, says Michael Halbig, president of InGen Technologies, a system engineering and process control company in Evansville, Ind., that installed extensive fiberoptic networks in the three treatment plants at the EWSU. While improperly installed fiberoptic cable and connectors still can be more fragile than copper, this is not the case when the appropriate cable, connectors and terminations for the application are selected and the proper installation guidelines are followed. Cable design and construction has progressed since the early days of the technology. When first used in commercial applications in the late 1970s, fiber cabling was not known for its ruggedness. Lets explore the validity of some of these myths and look at examples how optic networking technology is used to help solve problems in todays real-world industrial environments, while providing a foundation for future applications. Engineers and technicians in industrial facilities and system integrators are becoming more familiar with fiberoptic networking media as a complement to or replacement for copper cabling and connectors.Ī number of myths still surround the technology. ![]()
