Common Specifications
NOTE: Specifications noted below apply to all models unless otherwise specified in applica-
ble model section.
Optical Connector Type ST
Optical Fiber
Compatibility
50/125 µm or 62.5/125 µm, graded in-
dex multimode glass fiber rated for a min-
imum 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 lim-
ited 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 oper-
ate.
Data and Power
Connections
Removable screw terminal blocks
Construction Surface-mountable metal enclosure de-
signed to maximize
EMI/RFI shielding
Environmental
Operating Temperature –40°C to 74°C (–40°F to 165°F)
Storage Temperature –40°C to 85°C (–40°F to 185°F)
Humidity 0% to 95% relative, non-condensing
Accessories
