  • Common Specifications ;
    : Specifications noted below apply to all models unless otherwise specified in applicable model section.    
    Optical Connector Type: ST (most modules)
    Optical Fiber Compatibility: 50/125 µm or 62.5/125 µm, graded index multimode glass fiber rated for a minimum bandwidth of 600 MHz-Km. For 50/125 fiber, subtract 4 dB from the specified optical budget value.
    Optical Distance Specifications: Specified transmission distances are limited to the optical loss of the fiber and any additional loss introduced by connectors, splices, and patch panels. The modules are designed to operate over the entire optical loss budget range, so they do not require a minimum loss in order to operate.
    Data and Power Connections: Removable screw terminal blocks
    Construction: Surface-mountable metal enclosure designed to maximize EMI/RFI shielding
