FF-6800 Series Optical Cable Identifer is an intelligent instrument designed for the construction and maintenance of optical cable lines in optical communication system. In view of the complex wiring environment and the diffculty of locating faults during the construction and long-term use of optical cables, FF-6800 series can provide fast, effective and accurate fault solutions. When the target optical cable is bent or shaken, the optical cable identifer instrument can quickly capture the vibration signal and display it through waveform and sound, so as to locate the target optical cable quickly.
Optical Time Domain Reflectometer is a device used to detect failures in fiber optic links in a communications network. The operation of the device involves the production and transmission of a series of high-speed optical pulses within the fiber. Changes within the fiber create a back scatter according to the Rayleigh distribution. The pulses are then returned to the ODTR where their intensity is measured. The signal strength returned is an indication of the location and severity of the failure. ODTR is used not only for maintenance but also for installation of optical communication lines. In addition, international telephony networks also use ODTR to improve line connections.
The designs of all “high-power” SMA905 (HPSMA905) connectors currently available are essentially the same. A metal ferrule is held tightly around the cladding of a fiber optic with a polished (or possibly cleaved) end surface. Low power SMA905 connectors have stainless steel ferrules, but since high-power SMA905 connectors are prone to overheating, many have replaced the steel with copper (or copper alloy) to exploit the thermal conduction properties of that material. The ferrule design creates several problems when considering launching a high-power beam.
eCPRI is short for enhanced Common Public Radio Interface, it is published after CPRI. eCPRI standard defines specification which connects eREC and eRE via fronthaul transport network. It is an important technology for understanding 5G systems, LTE-Advanced and LTE-Advanced Pro.
