    Ciena, Cisco market share rises on service providers' metro WDM demand
    fiercetelecom | Posted: 22 Aug 2017, 09:58Ciena and Cisco are reaping the benefits as service providers shift spending from long haul to metro WDM (wave-division multiplexing) network builds.As a result of double-digit year-over-year North America growth in metro WDM, Cignal Al said in its second-quarter 2017 Optical Hardware Report that that Cisco and Ciena grew market share. The research firm said that Ciena’s North American optical equipment revenue increased by 21% year-over-year. Interestingly, the growth in metro WDM spending is creating greater demand for higher speed coherent ports, which are evolving from 200G to speeds as high as 400G later this year. Outside of North America, growth in China is notable as optical revenue rose 13% year-over-year for the first half ...

    Key Features


    Centrio 1-3KVAUsing Motorola Microprocessor control to rise the reliability of machine, but reduce size and lower the defective rate.
    Centrio 1-3KVAUsing module design to improve the reliability of the UPS, also simplify the  service maintenance. 
    Centrio 1-3KVAUnique bypass switch off function. After switching off the machine to BYPASS mode, users can further switch off the BYPASS. At the same time, the batteries will keep charging from mains. The function will guarantee batteries are always enough power on standby, and the connecting network will not be affected by mains voltage fluctuation and power problems.
    Centrio 1-3KVAThe improvement of LED indicators on front panel. 
    Centrio 1-3KVAUsing automatic Power Factor Correction (PFC) design, coupled with the latest IGBT power component, to create highly effective high-frequency online UPS, which can be more than 90% full load to minimize inside power consumption
    Centrio 1-3KVARS-232 communication port is adopted. Connecting to our power management software, on-screen monitoring of status of power supply and UPS is available.
    Centrio 1-3KVAUse Sealed Lead-Acid maintenance-free batterymaximizes battery life and optional battery bank extends backup time.
    Centrio 1-3KVAAutomatic diagnostic. When the UPS is powered on, it immediately performs an inspection of the components such as the inverter the battery as well as the load
    Centrio 1-3KVAEquipped with a intelligent SNMP slot to allow remote communication among various operation systems and remote monitoring of the UPS.
    Centrio 1-3KVAA charging card, which accepts up to 9A charging current, is available to be added. So that more sets of batteries can be placed to extend backup time.
    Centrio 1-3KVAReal-time alarm silencing function eliminates the unnecessary and annoying noises.
    Centrio 1-3KVAOutput short circuit protection.
    Centrio 1-3KVAInput over voltage and input frequency variation protection.
    Centrio 1-3KVAAuto restart and cold start function.
