The cost of installation for most fiber optic cable exceeds the cost of the cable itself, so ensuring the cable is good before installation is important. The first test the installer must do with a spool of cable is visually inspect it. The spool of cable should show no visible damage, indicating it has been properly handled during shipment. READ MORE

Most contractors assume it is necessary to field-terminate fiber optic cabling systems as part of every installation, but they are all looking for alternatives. The first alternative most people consider is to use prepolished/splice connectors, which use a mechanical splice to terminate the fiber. READ MORE

Having covered how to design and install fiber optic networks in recent columns, we are ready to start a new series, “Testing the Fiber Optic Cable Plant.” READ MORE

We’re nearing the end of our fiber optic cable plant installation; cable has been placed and spliced, so we’re ready to terminate the fibers for connections into patch panels or equipment. The location and types of connectors (generally SC, ST or LC) should have been decided during the design phase of the project. READ MORE

Premises cabling to support phones and PC networks hasn’t really changed much since it was first standardized by TIA-568 around 1990; It has just become faster, and Ethernet local-area networks (LANs) are now a thousand times faster. Plain old telephone service (POTS) has migrated to voice over Internet protocol (VoIP) on Ethernet LANs. READ MORE

Much of the fiber used in premises applications for computer networks and closed-circuit security cameras is multimode fiber. Multimode fiber has special application and installation quirks you need to know to install and use it separately. How familiar are you with multimode? Answers and explanations are in red. READ MORE

Installed cables often need to be joined together to complete a cable plant route; the route may be too long to pull or to place a continuous length of cable, since cable can only be manufactured in lengths of around 5 kilometers (km). One cable may be split to feed two or more cables, or even multiple cables will need to be interconnected at a single point. READ MORE
