The OC192 LR/STM64 LH 1550 card has the following specifications:
•
Note
You must use a fiber attenuator when connecting a fiber loopback to an OC192 LR/STM64 LH 1550
card. Use a 19 to 24 dB attenuator for 15454-OC192LR1550 or a 14 to 28 dB attenuator for
15454-OC192-LR2 (20 dB is recommended). Never connect a direct fiber loopback.
