Optical Power Loss Through Jumper Cables
When an 8265 is installed in a patch panel rack, IBM jumper cables are often used to
connect a media port to the patch panel. The use of jumper cables in this type of
configuration is recommended in your ATM network because each port regenerates
the optical signal at full strength as it was originally transmitted from the source end
system in the connection.
The total power loss at each IBM jumper cable is shown in Table 24.
