Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not 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.

Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments.
Statement 1051
Use a single-mode or multimode fiber-optic interface cable to connect your Cisco uBR7100 series router
to another router or switch. In general, multimode cables are gray or orange, and single-mode cables are
yellow. For SONET or synchronous digital hierarchy (SDH) single-mode and multimode fiber-optic
connections, use one duplex SC-type connector (Figure C-5) or two simplex SC-type connectors. (See
Figure C-6.)
