455886-B21-A
10GBASE-LR SFP+ SMF
1310NM 10KM REACH LC
Receiver power (damage, Max) 1.5
dBm
Note:
1. Average optical power shall be measured using the methods specified in
TIA/EIA-455-95.
2. Receiver sensitivity is informative. Stressed receiver sensitivity shall be
measured with conformance test signal for BER =1x 10
-12
3. Vertical eye closure penalty and stressed eye jitter are the test conditions for
measuring stressed receiver sensitivity. They are not the required characteristic
of the receiver.
4. Power budget is defined as the different between the Rx sensitivity and the Tx.
Output power of the interface.
5. Path penalty is intended as the power penalty of the interface between back-to-
back and the maximum applied dispersion.
