Notes:

  1. All terminology is consistent with GR-253-CORE, Issue 3 and ITU G.693. All values are worst-case end of life. Optical specifications meet or exceed equivalent GR-253-CORE requirements.

  2. The System Gain is Minimum Transmitter Power minus Minimum Received Power.

  3. Optical path penalty includes effects of dispersion, reflection, and jitter that occur on the optical path. The optical path penalty for 1310 nm is a maximum of 1.0 dB. The optical path penalty for 1550 nm is a maximum of 2.0 dB.

  4. Refer to GR-253-CORE for more information about these parameters.

  5. 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.

  6. The stated maximum loss budget equals the minimum system gain, minus the optical path penalty. Maximum loss budget is available for both station and transmission cable and splices.

  7. Although not specified, the OC-192 XFPs may tolerate some amount of negative dispersion, approximately −100 ps/nm.
