Fiber Optics Passive Component

June 11, 2011

A passive component is designed to route light energy from an input port to one or several output ports while losing as little energy as possible. The component must be stable and insensitive to environmental stress as well as insensitive to the state of polarization.

Vertical type of optical fiber fusion splicer

June 11, 2011

Vertical type of optical fiber fusion splicer closures looks like a dome, thus they are also called dome types. They meet the same specification as the horizontal types. They are designed for buried applications.

The optical GEPON technology

June 11, 2011

Using passive optical network (PON) access agreement with the platform for the transmission of ATM APON BPON/Ethernet technology and the platform for transmission to GEPON EPON/general frame structure and the platform for transmission GPON three types. GEPON EPON/is the Ethernet Ethernet (and the potential link layer protocol) and passive optical network access, the best PON (physical) combined together can very well adapt IP data access method of business.

OTDR stands for optical time domain reflectometer

June 10, 2011

OTDR stands for optical time domain reflectometer, and can be an optoelectronic instrument that is employed to characterize specific optical fibers. This tool injects optical pulses in series into fibers for screening along with extracting lighting form that fiber that is reflected back again from points in that specific fiber where the refraction changes. The strength of return pulses are then measured in time and then plotted below a function of the fiber length.

Troubleshooting Your Optical Fiber Networks

June 10, 2011

Introduction to OTDR - OTDR does not measure loss, but instead implies it by searching at the backscatter signature on the fiber. It does not measure cable television plant loss that could be correlated to energy budgets.

The software programs of Pulse Suppressors

June 10, 2011

Pulse suppressors, also referred to as OTDR start boxes, delay lines or "Dummy Fibers" are accustomed to occupy OTDR "dead zones" which enables accurate loss measurements on near end connections on the fibers below test. Suppressors may also be used in an academic setting to simulate systems and throughout installation and troubleshooting.
