    8.1 Overview of Electrical-layer Service Board Naming


    Conventions
    This topic introduces the naming conventions for electrical-layer service boards.

    For the OSN 1800, the electrical-layer service boards are named in accordance
    with the following naming structure:

    Figure 8-1 Naming Structure

    Generally, a board name consists of 14 letters and digits in total:


    ● 1 to 4 bits indicate the hardware version, such as TNF1, TNF5, and TNZ5.
    ● 5 to 11 bits indicate the board name. Different types of boards have different
    board names, which contain less than or equal to seven bits. For naming

    conventions for different electrical-layer service boards, see the detailed


    description of each type of board.
    ● 12 to 14 bits indicate the extension name of the board.

    8.2 Dimensions of Boards


    This topic describes the dimensions of the boards.

    CAUTION

    Always wear an ESD wrist strap when holding a board, and ensure that the ESD
    wrist strap is well grounded, to prevent static discharge from damaging the board.

    excluding dimensions of protruding components such as ejector levers, terminals, and optical
    modules.

    8.3 Symbols on Boards


    This topic describes the warning symbol and label affixed to all boards.

    DANGER

    It is strictly forbidden to stare into optical ports during fiber installation and
    maintenance, because the laser beam inside the fibers would hurt your eyes.

    Table 8-1 Labels on boards


    Label Type Description

    Laser safety class label This shows that the laser


    safety class of the board
    is HAZARD LEVEL 1M,
    indicating that the
    output optical power of
    the board optical port
    ranges from 10.00 dBm
    to 21.3 dBm (10.00 mW
    to 136 mW). It warns
    users not to look directly
    at fiber connectors
    without using protective
    measures. Always use an
    optical instrument that
    can attenuate optical
    power when working
    with boards.

    The laser safety class


    label CLASS 1 indicates
    that the maximum
    optical power of the
    optical port is less than
    10 dBm (10 mW).

    8.4 Board Barcodes


    The barcode of a board is provided on the front panel of the board and shows the
    basic information about the board, including the BOM number and delivery time.

    One-Dimensional Barcode Label


    Figure 8-2 shows a one-dimensional barcode, and Table 8-2 provides the
    description of the barcode.
