One of the reasons fiber optics have become popular for surveillance cameras is its speed. The familiarity of Northeast Remote Surveillance and Alarm, LLC contractors with fiber optics and its installation processes makes them a preferred installation contractor. Cameras use the same types of fiber, multi-mode or single-mode and the same connectors that are used in other fiber optic systems. If spare fibers are available, video may be sent over the same cables that carry LAN, telecom or CATV signals. Thus, in a corporate network or utility power generation facility, for example, currently installed cabling may be available for security system usage.
While fiber optic high speed security cable is hard to tap and impossible to jam, it is possible to disrupt links by simply cutting the cable. Therefore, most security systems run fiber optic cables in conduit, usually metal, for protection. An optical fiber is a flexible and transparent fiber made by glass or plastic with a diameter comparable to that of a human hair. Optical fibers are used to transmit light between the two ends of the fiber and are used in fiber-optic communications over long distances and at high bandwidth. Moreover, compared to electric circuits, fiber-optic systems are immune to electromagnetic interference and have high processing speeds.
If pulling tension is high due to friction in the conduit, use a suitable lubricant, which means compatible with the jacket of the fiber cable and the conduit. Different lubricants are needed for outdoor and indoor usage, since indoor lubricants are designed not to drip out of conduit. Special dedicated lubricants for fiber cable are available, and lubricant manufacturers should be consulted for advice on choosing and using these lubricants.
Not following these installation guidelines can cause serious problems. For example, an installer on an airport project pulled a cable through a long distance and a large number of 90-degree turns without lubricant. When the fibers were tested with a LED test source and power meter, all had higher than expected loss at 850 nm, but some had an even higher loss at 1,300 nm. All Northeast Remote Surveillance and Alarm, LLC installers are trained to properly run fiber optic cables. Remember that fiber shows higher stress losses at longer wavelengths, so the higher loss at 1,300 nm showed the cable had been over-stressed during installation, probably affecting its long-term reliability. Replacement was the only reasonable fix.
You may be able to run power for the equipment in the same conduit as the fiber according to most codes. Check the local inspectors for clarification on this issue. Custom composite cables with power conductors and fibers are an option worth considering if a large number of systems is being installed.
