For example, you can install all the electronics for a network in one communications closet for a building and run straight to the desktop with fiber. Even though fiber optic cabling is superior to gigabit Ethernet cabling in a number of ways, a home network may not benefit significantly from this technology when one takes the costs associated with an optical fiber network into account. Optical fiber with fiber modem is used to extend a LAN beyond its limit. So when it comes to costs, looking at the cabling component costs may not be a good way to analyze total network costs. Most networks are designed around structured cabling installed per EIA/TIA 568 standards. Since ports in modular hubs must be added in modules of 8 or 16, it's not uncommon with a hub in a telecom closet to have many of the ports in a module empty . Industrial plants use lots of fiber or distance and noise immunity. When using pulling equipment to install cable, measures should be taken to ensure that the MRCL is not exceeded. Fiber optic cables have grown by leaps and bounds since the 60s. While fiber is still primarily limited to LAN backbones in the premises cabling … A fiber optic cable refers to any cord that uses light to carry signals from one source to another. Conversion from copper networks is easy with media converters, gadgets that convert most types of systems to fiber optics. A properly designed premises cabling network can also be less expensive when done in fiber instead of copper. Both telcos and CATV operators use fiber for economic reasons, but their cost justification requires adopting new network architectures to take advantage of fiber's strengths.
