  • Design and performance of ultra-high-density optical Fiber Cable with rollable optical Fiber ribbons
    Optical Fiber Technology, 2010
    Co-Authors: Kazuo Hogari, Yusuke Yamada, Kunihiro Toge
    Abstract:

    Abstract This paper proposes a novel ultra-high-density optical Fiber Cable that employs rollable optical Fiber ribbons. The Cable has great advantages in terms of Cable weight and diameter, and Fiber splicing workability. Moreover, it will be easy to install in a small space in underground ducts and on residential and business premises. The structural design of the rollable optical Fiber ribbon is evaluated theoretically and experimentally, and an optimum adhesion pitch P in the longitudinal direction is obtained. In addition, we examined the performance of ultra-high-density Cables with a small diameter that employ rollable optical Fiber ribbons and bending-loss insensitive optical Fibers. The transmission, mechanical and mid-span access performance of these Cables was confirmed to be excellent.

  • Ultra-high-density optical Fiber Cable with rollable optical Fiber ribbons
    OECC ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology, 2008
    Co-Authors: Kunihiro Toge, Yusuke Yamada, Kazuo Hogari
    Abstract:

    We propose a novel ultra-high-density optical Fiber Cable employing rollable optical Fiber ribbons that can be mass spliced. These ribbons are specially designed for high-density assembly in the small core of the Cable.

  • Optical-transmission characteristics of optical-Fiber Cables and installed optical-Fiber Cable networks for WDM systems
    Journal of Lightwave Technology, 2003
    Co-Authors: Kazuo Hogari, Shigekatsu Tetsutani, Jian Zhou, Fumihiko Yamamoto, Kiminori Sato
    Abstract:

    Many Cables containing 1.3-μm zero-dispersion single-mode (SM) optical Fibers are installed in trunk and access networks. Recently, there have been a number of studies on wavelength-division-multiplexing (WDM) systems designed to increase transmission capacity and flexibility. If we can construct WDM systems using SM optical-Fiber Cable networks designed to transmit using wavelengths in the 1.3-μm window (O-band), this will prove very effective in reducing construction costs. It is therefore important to examine the wavelength dependence of the transmission characteristics of SM optical-Fiber Cables and networks that have already been installed and in which several optical Fibers are joined. In this paper, we describe the measured optical characteristics of SM optical-Fiber Cables and installed optical-Fiber Cable networks at various wavelengths. The optical characteristics were stable in the 1.46 to 1.625-μm wavelength range and we confirmed that the installed SM optical-Fiber Cable networks could be used for WDM system applications.

  • Design and Performance of 2000-Fiber Cable
    Journal of Optical Communications, 1993
    Co-Authors: Kazuo Hogari, Kenji Nakayama, Fumihiro Ashiya
    Abstract:

    This paper proposes high-density and high-Fiber-count optical Fiber Cable, containing Fiber ribbons inserted into slots and with a total number of Fibers exceeding the current maximum of 1000. Cable structure and Cable diameter, which are important factors for economical and efficient construction, are investigated theoretically and experimentally and the optimum structure for achieving small Cable diameter is obtained. Based on the results, a 2000-Fiber Cable was manufactured and its performance was evaluated. The transmission, mechanical and midspan access characteristics of the Cable was confirmed to be excellent

  • Analysis on transmission characteristics of special optical Fiber Cable for power communication on upgrading of optical communication system
    Dianwang Jishu Power System Technology, 2010
    Co-Authors: P Gao, Yongxing Wang, H Ding
    Abstract:

    Upgrading of transmission rate of optical communication system makes demand of transmission performance of optical Fiber Cable. According to the demand of upgrading of transmission rate of special optical Fiber Cable for power communication, the influences of transmission characteristics such as attenuation, chromatic dispersion and polarization mode dispersion on upgrading of communication system are analyzed and the testing methods of the three transmission characteristics of optical Fiber Cable are presented respectively. A testing system is set up and actual measurement of the transmission characteristics of being operated optical Fiber Cable line is performed. The proposed analysis and testing method is available for reference in the evaluation of transmission characteristics of optical Fiber Cable line while the communication system is being upgraded.
