    1. Introduction
    (1) This specification describes the optical performance and mechanical characteristics of the “Duplex Armored Optical Fiber Patchcord”The “Duplex Armored Optical Fiber Patchcord” contains two fibers. in the metal tube and it’s mechanical characteristics are much better than the traditional optical fiber patchcord.
     
    (2)Compare with the traditional optical fiber patchcord, the mechanical characteristics of Kaiphone’s “Duplex Armored Optical Fiber Patchcord ”are much stronger, electric cable –like handling and easy to installation.   
     
    (3)This latest “Duplex Armored Optical Fiber Patchcord” is different from the traditional patchcord for the characteristics that it has been developed with a micro diameter stainless flexible metal tube with flame-resistance PVC coating to protect this fragile optical fiber. In order to ensure the firmly conjunction, we also offer relative strong  connectors. This unique design reduces the difficulties of installation and extends the fiber’s life.  
     
    (4)Like the traditional patchcord, Kaiphone’s “Duplex Armored Optical Fiber Patchcord.” can be used as the connection between the ODF (Optical Distribution Frame) and equipments, connection between floor and floor or emergency testing connection.

    2-1 Description  The duplex armored optical fiber patchcord was mainly constructed of armored optical fiber cables and connectors. Its advantages are anti-tensile, anti-pressure and easy to install. The duplex armored optical fiber patchcord can be used in the connection between the optical equipments in the indoor central office. Its detailed specification was described in the following sections:
     2-2 Structure
     As shown in fig.1 and fig.2, the duplex armored optical fiber patchcord was constructed of the following parts: 2 optical fibers, stainless metal tube with jacket, branching connectors, branching stainless metal tube with jacket and optical connectors. The followings are its detailed specification descriptions.

    Each two 250um bare fibers in the stainless metal tube coated with tight or semi-tight PVC jacket and it’s outer diameter is 600um.We distinguish these two fibers with different colors, usually blue and white colored jacket.   
     2-2 Main stainless metal tubes with jacket
     The two 600um optical fibers were protected by the stainless flexible metal tube. The material of this tube is 304 stainless metal. Its  corresponding diameters and mechanical characteristics are as table 2.

    In order to increase the tensile strength of this main stainless metal tube, we surround the main stainless metal with Kevlar and metal braiding as shown in fig.1.We coat this braiding metal tube with PVC or PE jacket according to the customer’s requirements. In the normal situation, we use the PVC material as the metal tube jacket and the jacket color is blue for single mode fiber and grey for multi-mode fiber.     
     
    2-2-3          Branching connector
     
    As shown in fig.2, the functions of branching connectors are to connect and fix the main stainless metal tube and the branching metal tubes. These branching connectors are made of plastic materials and the size of branching connectors are 14 mm in width,25 mm in length and 9 mm in height.
     
    2-2-4          Branching stainless metal tube with jacket
     
    As shown in fig.1, the branching metal tube was constructed of metal tube, Kevlar,metal braiding and the outer jacket. Just like the main metal tube, the branching metal tube protects the fragile optical fibers and its diameters are as table 3.

    Overall diameter with jacket 3.3+/-0.1mm 3.0+0/-0.2mm 2.5+/-0.1mm
     
    In the normal situation, we use Type III metal tubes as the branching tubes.
    2-2-3          Optical connectors We use the traditional optical connectors as our armored optical connectors and the optical connectors characteristics are shown in table 4.

    3. Lable and Package
    3-1 We distinguish each fiber with the colors of the branching metal
    tube jacket. Each different color of jacket corresponds to every different optical fiber. For duplex armored optical fiber patchcord, one branching tube is blue, the other one is white. It is easy for customers to tell from each fiber. .    
    3-2 Each armored optical fiber cable should have marking on the outer jacket of the main metal tube or adhere to an additional tape.
    The marking on the outer jacket or tape shall appear the following details:
      (a)Manufacturer’s name
    (b)Type and counts of optic fiber e.g .SM-2C
    (c)Date of manufacture
     The marked intervals are not less than 1 m throughout the cable length
