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.
4.26.3 OC48 LR/STM16 LH AS 1550 Compatibility
Use the XC10G card, the TCC+ card, the new 15454-SA-ANSI shelf assembly, and Software R3.1 or
higher to enable the OC48 LR/STM16 LH AS 1550 card. The OC48 LR/STM16 LH AS 1550 card uses
the BTC backplane interface to provide recognition in both the high-speed and multispeed slots.
