All terminology is consistent with GR-253-CORE, Issue 3. All values are worst-case end of life. These PTMs are OC-48 compliant, and OC-3 and OC-12 compatible..
The System Gain is Minimum Transmitter Power minus Minimum Received Power.
Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm optics is normally 1.0 dB.
Refer to GR-253-CORE for more information about these parameters.
For all packs and PTMs where the Minimum Loss Budget (MLB) is 0, no attenuator is required for loopbacks. For all packs and PTMs where the MLB is greater than 0, an attenuator is required. The value of the LBO must be equal to or greater than the MLB.
The stated maximum loss budgets are assumed to be worst-case values including losses due to splices, connectors, optical attenuators or other passive optical devices, and any additional cable margin.
