The function and advantage of the OTDR OLT optical module

The fiber to the home (FTTH) is an important technology of the wired access broadband in 21 century. And PON represents one of the most widely deployment network architecture.  At present, the global telecom operators are trying their best to reduce the operating network cost. At the same time, they [ Continue reading…]

something about optic fiber Splicing

A splice is a device to connect one fiber optic cable to another permanently. It is the attribute of permanence that distinguishes a splice from connectors. Nonetheless, some vendors offer splices that can be disconnected that are not permanent so that they can be disconnected for repairs or rearrangements. The terminology can [ Continue reading…]

BASIC CABLE DESIGN

1 – Two basic cable designs are:   Loose-tube cable, used in the majority of outside-plant installations in North America, and tight-buffered cable, primarily used inside buildings.   The modular design of loose-tube cables typically holds up to 12 fibers per buffer tube with a maximum per cable fiber count of more [ Continue reading…]

The Ports On CWDM and DWDM MUX/DEMUX

It is quite common to use CWDM or DWDM to increase the existing fiber optic network without adding any fibers. Using WDM MUX/DEMUX is necessary to build a CWDM or DWDM network. Now there are different ports installed on the CWDM and DWDM MUX/DEMUXs to add more beneficial to the fiber optic [ Continue reading…]

Guideline for Copper Cabling Installation

Copper cabling has been in use since electricity was invented and its quality has continued to improve. Network managers pick copper cabling for various reasons. For instance, copper cables, especially UTP cables, are as inexpensive as optical fibers and easy to install. Moreover, the installation methods are well understood, and the components [ Continue reading…]

Typical Outdoor Fiber Optic Cables

Fiber optic cable provides protection for the fibers from the environment encountered in an installation. Outdoor Fiber Cable is designed strong to protect the fibers to operate safely in complicated outdoor environment, it can be buried directly, pulled in conduit, strung aerially or even placed underwater. While indoor cables don’t have [ Continue reading…]
