This what I found on CCO
http://www.cisco.com/warp/public/cc/pd/rt/3600/prodlit/atmnm_ds.htm
OC-3c/STM-1 Optical Interface Power Interface
OC-3c/STM-1 Multimode
-14 dBm TX Power (maximum)
-19 dBm TX Power (minimum)
-14 dBm RX Power (maximum)
-30 dBm RX Power (minimum)
11 dB Budget
OC-3c/STM-1 Single-Mode Intermediate Reach
-8 dBm TX Power (maximum)
-15 dBm TX Power (minimum)
-8 dBm RX Power (maximum)
-28 dBm RX Power (minimum)
13 dB Budget
OC-3c/STM-1 Single-Mode Long Reach
0 dBm TX Power (maximum)
-5 dBm TX Power (minimum)
-10 dBm RX Power (maximum)
-34 dBm RX Power (minimum)
29 dB Budget
Connecting two long-reach single mode ports back-to-back in a very short
span will require the use of optical attenuators (minimum 10 db loss
required).
Seems to me that I should be ok connecting the OC-3c/STM-1 Single-Mode
Intermediate Reach back to back. Do I feel confident "NO"
