The launch of TeliSwitch remote control optical divide ratio of PON-AODF system

On July 24, 2012, Israel optical wiring equipment provider TeliSwitch solutions company introduced patent support PON network dynamic change of optical divide ratio of PON-AODF system. TeliSwitch said, the existing PON operator in PON network planning, limited to the technical conditions, usually choose 32 or 64 fixed optical divide ratio, therefore required in the initial business needs and future business requirements make compromise between. When the PON network penetration is relatively low, the OLT port number is a waste, because even if there is only one customer, OLT will be connected to the splitter. In addition, the high splitting ratio also limits the operators to provide high bandwidth service ability. Their use of newly developed PON-AODF system, can be achieved by remote control PON light splitting ratio and save the operator for more than 50% of the OLT port number. The system maintained in PON system passive properties but also for the system to increase the adaptive ability of optical divide ratio regulation. TeliSwithc said their PON-AODF system for PON carriers to provide on-demand OLT port capacity, thus greatly reduce the system operation cost. AODF:Automated Optical Distribution Frame, automatic optical fiber distribution frame. PON:Passive Optical Network, passive optical fiber network.

Rosenberg introduced the optical fiber LC quick plug connector

Cloud computing virtualization Fabric complex network architecture of the launch, fiber network as the main transmission and network management carrier, for cloud computing data center is more and more high density fiber application environment, Rosenberg company has recently launched a patent technology ( Quick Release ) LC quick plug connector. This rapid plug connectors with IEC61754-20 international standard LC connector. The launch of the LC duplex connector incorporates a patented locking releasing device. Rosenberg German R & D department, Dr. Dr. Gerald Berg explains: " a new generation of Quick Release LC connector can be good at data center high density and the maintenance of balance before, patent lock release technique and optical fiber bending insensitive technology, greatly enhancing the optical fiber system in data center application convenience and reliability. " With the explosive increase of servers in the data center, data center requirements significantly reduce the server and storage equipment and network communications equipment covers an area of, and enhances the calculating density, improve the overall data center utilization and efficiency. Data center optical fiber distribution frame density also has ascend beyond the 1HU 96 core and 288 core high density 4HU. The traditional LC connector in high density optical distribution frame of closely arranged connecting port plug operations more difficult, sometimes need the help of other means of operation, increases the operation difficulty and cost, and easy interference to other optical fiber channel, affect the data transmission, thereby reducing the reliability of data center. In view of this situation, Rosenberg patented LC quick plug connector, accord with human body engineering principle, finger pushing and drawing LC optical fiber connector end of the optical fiber connector plug, you can easily complete the swap operation. Especially out of time, an optical fiber connector plug corresponding to the lock unlocked, a new plug device solves the problems of high density application, at the same time with the bend insensitive optical fiber combination, the availability and reliability of the fuse. As the German brand of Rosenberg company has paid attention to the development of the data center, for 4 consecutive years was rated " best data center cabling supplier" and for 3 consecutive years was named "China's top ten brands of wiring ". Innovation and strict is the company's main values, is dedicated to Chinese users with the most excellent data center cabling solutions as their main goal.
