Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam or view directly with optical instruments. Viewing the laser output with
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance
of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other
than those specified may result in hazardous radiation exposure.
To connect the customer-supplied optical fiber cable to the SC/UPC optical ports, follow these steps:
Step 1 Connect the input optical fiber cable to the input connector (see Figure 2-2). Avoid making sharp bends
in the cable.
Step 2 Connect the output optical fiber cable to the output connector (see Figure 2-2). Avoid making sharp
bends in the cable.
